On balance, file under "learning experience"

Warning: A long and photo-heavy post follows!
In a rare photo that is not of some part of a partially disassembled boat, your correspondent is seen at the helm with fellow Yachtmaster prepper John C. at the companionway, both looking, I think, suitably nautical. Photo (c) Sailing School Brittany.

It may seem facetious to say that the greatest skill a sailor can exhibit is balance. It seems self-evident, as we are enjoined to "stay on the boat", naturally, as the boat, unless in the process of burning or exploding, is inherently safer than off the boat, in the water or (better) in the liftraft or the helicopter harness.

Most sailors try to avoid such situations, and yet, we are seeing on a regular basis of late the consequences of insufficient preparation for a life at sea in a small boat every year. One might say that the balance of having sufficient funds and leisure to go a-sailing is slightly at odds with the time required to develop the necessary skills. Acquiring the boat's a doddle.

Now, the boat we've got (S/V Alchemy) for high-seas mucking about has been both on land or stationary in the water for a number of years. Opportunities for sailing her have been precisely zero, although I did throw her about in big air sufficiently before The Great Refit. I began, thanks to such deliberate thumpings, to feel fairly confident that she's fit for the purposes of wandering the world's oceans in relative safety and even comfort.

Now, while we have available to us the original 33 footer (S/V Valiente), the amount of sailing we've be doing in her has been neither extensive nor particularly challenging. "A nice day out" is the usual fare, with a couple of occasional 30 knot rides with friend Jeff, who, like me, enjoys when the boat moves. But, en famille, this is because "time for sailing" has fallen below the slots of "work to pay for life and boat refitting and fractionally employed wife and child", "parenting" and "boat refitting". I play in a basement band on some Friday evenings, but that's essentially it. I have been aware for some time that my sailing skills, despite some time spent on deliveries and in races, were becoming somewhat eroded, if not actually stale.

Not a model of balance, really.

So I purposed, apparently audibly, to attend a Royal Yachting Association course. I knew I wanted to learn about all things tidal, about calculating for current, about mooring and anchoring under sail, powering off a spring line against wind, and so on. Some of these things I had done in the classroom, and some in one or both of our boats, but the math aspect of calculating current, tide and their effect on course to steer was, shall we say, near-virgin territory. Our original plan was to have a shakedown cruise to Canada's Maritime provinces and to overwinter in Halifax, where myself and my wife would immerse ourselves in the lore necessary to take the Yachtmaster Coastal course, for which we both qualify in terms of offshore miles, and which largely agrees with our watch-keeping and skippering experience, and for which we possess the Canadian versions of radio operator's and marine first-aid certifications.

Funny looking port-side burgee, if you ask me.


I mentioned "audibly". My friend and, as it has turned out, patron John C. likes to take sailing courses once his boat is hauled out and likes company. So when he suggested that he would splurge some of his surplus air miles to get me to an RYA Training Centre to take a week of Yachtmaster prep, it didn't just seem churlish to refuse, it seemed stupid: If one is anticipating going into tidal waters (such as the St. Lawrence and the coasts of New Brunswick and Nova Scotia, parts of which have among the greatest tides on Earth), one should perhaps bone up on the topic.

The Bay of Quiberon and the Golfe du Morbihan: Tides, they have 'em.

The problem was first "what place", and then "what time". John wanted to go in November after our boats were hauled out, and I knew I had a great deal of client work (which I could ill-afford to decline, particularly if I was going to pop for an RYA course in some distant area) in hand, plus some regular, meaning cyclical, work commitments, plus hauling two boats. Luckily, John has a more open calendar than myself, and a more probing mind when it comes to logistics. Having little response from a number of RYA "shops" here in Canada and in some places either harder to reach (southern Portugal) or less clement (mid-November on the English Channel), we fixed on Sailing School Brittany, run out of Vannes on the south coast into the Golfe du Morbihan and Quiberon Bay.

A fascinating, compact cruising ground and what I would describe as a laboratory for sail training in tidal conditions.

John freely admits his vices mingle with his virtues as expressed by his love of fine food and wine. Add to that his fluency in French, the (relatively and conditionally) benign late-fall weather on the south side of the Brittany peninsula, the tidal and current complexity of said area, and the British-run (and yet equally Francophile) RYA-certified sailing school, and the die was cast for France.

Personally, I was working until about an hour before I hopped into the car for the airport on Nov. 8. I returned on the 17th and have been working pretty solidly since then. The evidence is the silence in this blog: if I'm posting a lot, it's either too hot or too cold to work on the boat, and I haven't got the right amount of freelance gigs. But now we are back to the question of balance: While anticipated as an order of events, this "wedge in a sailing course in the shortest possible window" will re-emerge as Not the Best Plan later in this post.


Once located after a chastening cloudburst, this was Hotel Quite Acceptable.

But I won't foreshadow overmuch. The trip was an ordeal, as I find all air travel to be since You Know When, but it wasn't worse than I had expected and everyone was civil for a change. Upon landing in Paris, we opted to change trains to one for the largish town of Vannes in Brittany arriving three hours earlier, meaning we'd be awake and moving for 25 instead of 28 straight hours. Some hustling and rapid French exchanges later, and we were zooming in uncomfortable seating through the French countryside, which seemed remarkably untouched by fall colours, if garlanded in grey, weeping clouds and stoles of sunlight.

One of the publications I regularly work on has a distressingly similar palette to this French "W.C."
A 45-minute nap, a shower and a brisk, interrogative stroll through the helpful and friendly Vannetais citizenry later, and John and I were plonked in front of a very tasty cafe dinner. And wine. Lots of wine on this trip. A restorative if not entirely sufficient sleep followed. Alison, Missus Sailing School Brittany, picked us up the next morning (a Sunday, and despite what you may have heard, they are still very keen on church bells in France) and drove us to La Trinité-sur-Mer, a small town at the north end of Quiberon Bay. Regarding the various little, and often riverine, ports we sailed to: it's perhaps a mark of how popular this area is among French sailors that most of the towns seemed vestigial to the vast marinas beside and in some cases around them.  Even by eyeball, most of the marinas seemed to sport between 1,500 and 2,000 slips, few of which seemed empty, even if many, many boats had clearly not been visited in some time. If there's a euro crisis in Europe, I would suggest it's skipped this bit.

The IDEC trimaran: Around the world, solo, in 57 days. Yikes. It looks faster than a moving boat tied to a dock.
To be fair, this has got to be the heartland of French sailing, and France is arguably the most sailing-crazy nation on Earth. The English would prefer to think they are the cradle of yachting, and they are no slouches, but they name streets after local guys here, guys like Francis Joyon, Eric Taberly, Olivier de Kersauson and even an old guy named Jacques Cartier...I think the Tragically Hip wrote about him.

One of Taberly's novel...and successful...experiments, Pen Duick V, the first boat with water ballast tanks. We docked across from it. This was at Port-Haliguen, on the "presqu'île de Quiberon".
Anyway, apart from the reasons we were there, I would say "cruiser and racers' paradise" to describe the well-sheltered Bay and the even more protected (if wickedly tidal in spots) Golfe is no exaggeration. It's roughly about a hundred square miles in area, and it would be hard to sail for more than two to three hours before hitting a vast, well-equipped marina with very good food and drink only a steep ramp (tidal, remember?) away.

Oh, there's a nice metal beauty!...across from Pen Duick V.

Hmm. Nothing online about this impressive vessel, even given its unusual name of Catgil.
We were dropped by Alison at La Trinité-sur-Mer to meet her husband Dave, a former businessman turned professional sail instructor. Dave skippers Tamara, a lightly used and exceptionally well-kept Bavaria 36 from the middle of the last decade.

Tamara at Vannes across from le Capitainerie, the rather official clubhouse for the popular Vannes marina
And here's a video of that vintage of Bavaria, as driven by a Dutch fellow in the Channel:

Please note that apart from a brief 30-odd knot squall that kicked up very Lake Ontario-like square chop of about a metre inside the Golfe, we had very little in the way of wave action. Currents, however...

Now, as for the rationale of picking an RYA course, it can be summed up in terms of throughness, a fairly rigorous review of instructor and examiner standards (although John has found this last part a little on the variable side in the past), and the general respect given to RYA certification well beyond Europe.

I won't delve into the debate, perhaps new for some of my American readers, on the merits of yachting education and subsequent certification, except to say that I personally believe that given my informal, scattershot and non-familial (my father was in the British Merchant Navy, but personally never messed around in boats beyond enjoying an occasional row) apprenticeship to the sea, boat handling and navigation skill sets must be objectively measured against some sort of knowledge-based and experentially evaluated standard.

John and I concur that Canada does not have such a standard, save for Canadian Power Squadron course and some auxiliary instruction of what seems to me to be a touch feeble. Enough to keep one off the rocks, but insufficient for ocean-crossing. I'm not alone in this: there are RYA schools in Canada, but they were neither clement, as well-provised or as logical to attend as was the one in Brittany.
With the RYA, there are two paths: one leads to better skippering of a private yacht, and the other to more commercial ends, including chartering or smaller commercial vessel operation.


The RYA, by contrast, has graduated courses to take in a fairly linear way from lubber to skipper well-prepared to go pretty much anywhere. Perhaps a touch ironically, the RYA courses were originally devised to keep the government out of boating, and yet have become a de facto regulatory reference in places where no such boating standards exist. It can lessen the cost of one's insurance, as well.

Now, does the average boater need RYA courses? No, not necessarily, but then, who is the average boater? A weekend fair-weather sailor could be hit by a squall stronger than any I've ever experienced (the middle 60s on Lake Ontario, the middle 40s in the Atlantic). As an analogy, automobile commuters don't need winter or defensive driving courses, either, but it's hard to argue that having such training can increase one's odds in challenging conditions.

For North Americans, ASA, CYA and various Power Squadron courses can work as sail training. If you throw in plenty of sailing in all conditions (which many sailors frankly dislike, avoid and feel challenged by, understandably), plus a bit of yacht delivery work, plus some first aid training, you would generally match the lower tiers of RYA certifications. But what would be lacking is that measuring stick whereby one's knowledge (and reaction speed and boat handling choices) are compared to a recognized standard. What would be lacking is balance.

That's what I was looking for, and, Neptune help me, that's what I found.

Port Navalo lighthouse at the entrance to the Golfe du Morbihan. This is the spout: the sea pours in and out.


Still jet-lagged and mentally compressed (well, I was mentally compressed), Dave, John and myself left for five days aboard Tamara.  Dave's Bavaria 36, which he bought out of charter, sported three cabins, which I thought was hard to do on a 36 footer, but proved quite serviceable in actual use. The general idea on this sort of course is to sail from port to port in the daytime, and to include some night passages for the purpose of taking bearings, estimating distance off and generally playing "spot the phare" against a sometimes busy background.  French buoyage is generally excellent, if often unlit, and Quiberon's suitability as a cruising and as a sailing instruction zone of high relevance is based on the fact that it's full of rocks, ranges, shoals and markers for all the above. The French nautical charts are easily the match of the British ones, and Dave said he went through three sets of the local area per instructional season...even with soft "2B" pencils, the constant erasure and handling wears even the sturdy paper out.

Oh, buoy: Throw in sound and light signals and day shapes RWG light sectors and you've got a brightly coloured stew.

Back to Sunday: After a brief but thorough safety drill from Dave, who as expected, keeps his boat in full compliance, as far as I could see, with all flares, extinguishers, lifejackets (what we call PFDs) and so on, we shoved off into a sunny going cloudy going breezy day, i.e. Brittany sailing weather. We preceded past the unfamilar-to-me IALA-A buoyage (red right leaving on lateral marks!) south into the Bay making for Port-Haliguen, where my failure to recycle my knowledge of the rarely seen (on Lake Ontario) cardinal buoys would first rear its empty head.

This was better than the one I got from the CPS 14 years ago.

See? No grid beyond the rose, nor error offsets, nor handy scale to use with dividers. Oh, yes, there were dividers.
 On an RYA course, one uses "traditional" (read: non-GPS-based) coastal navigation, assuming one can see the coast. This can involve working out a three-point fix, and keeping dead reckoning from a last known fix, such as the aforementioned buoys and markers.  I won't define these terms except to say it's possible to get a little rusty with concepts like back bearings and actually consulting the boat's deviation chart and calculating the annual compass variation (also called declination) in order to determine a compass course to steer.

If you can't see the lighthouse ten miles ahead of you, try to see the lighthouse ten miles aft.

Now, I know and actually use this stuff in my own chartwork...I don't have a working plotter on Valiente, and that means the GPS is used (when it's used at all) to determine arrival time estimates, distance to the next waypoint, and so on. Most of my nav is still paper-based and my pilotage is done using hand-bearing compasses. In other words, I'm mostly in this headspace already. But it's markedly different in a new environment, with new numbers (the variation in Lake Ontario is considerably larger and, at circa -10 degrees, easier to manipulate without pen and pad), the effect can be a little disorientating. Or so I found.

The bible, or near enough, as it was an object of near-religious veneration and scruntiny.


Thrown into that mix is a tidal range of about 4.5-5 metres. "Chart datum" isn't a worry so much on Lake Ontario, the depth of which is for reasons of shipping kept above it. Here the tides are, while not extreme, a big consideration, and considerable research is required. It's picky, if not overly complex, but the upshot of understanding tides is to grasp that the hours around high and low water are (usually) when the current is most slack and the current imposed on the water is at its least. Conversely, the point between the high and low tides can be (usually) the hours during which the waters are moving fastest, which in turn can help or hinder one's progress.

Note the "usually" there: In places with unusual geographical or seafloor features, or which feature some sort of restriction, there can be a predictable delay in the tidal streams, and a corresponding misalignment of the expected currents.  So you could have the same tide both "with you" and "against you" in a rather short period of time and stretch of water. Welcome to Brittany!

Monkish postures aside, this was a fairly common scene aboard Tamara. And yes, we all require geezer glasses! (c) photo by J.C.

Luckily, there are crib notes and techniques and almanacs to help turn this sort of voyage planning into a Big Math-light Picture.  Briefly, one might determine from an  almanac of tidal ranges a particular day's tides from what's called a primary port. The closest one to us was Brest, so we note the tides at Brest (there were two highs and two lows per 24 hour period), correct for local time if necessary (this is why you want a clock reading GMT/Zulu/UT or whatever you're calling it); extrapolate to the closest secondary port (a plus or minus X number of minutes plus a height offset);  and then consult the tidal stream information in your (in this case) handy Bloc Marine book for your area and the time of day/tide during which you'll be sailing. It will be quite evident if you'll be helped or hindered by billions of litres of water moving around, or whether the wind will oppose the current, making for a potentially nastier trip. Factor in the current offset into your proposed course to steer (the concept of tidal current set and drift). It may appear when that number is finally determined that one's boat is crabbing at an angle to reach a selected waypoint. That's because it is.

Again, this is stuff I knew. I covered tidal concepts in my first CPS course in 1999. But I hadn't really experienced firsthand; when one leaves "with the tide" you don't really think about it at sea until you again approach the land. I find it fascinating, and doable, but I needed to refamiliarize myself with it, because it came back slower than a man paying to learn would prefer. Apologies if I've made errors in description and logic...I'm typing this out from memory, not from the books...





...I didn't have time to do more than leaf through, glancing at chapter headings.

This is a Breton rock. Most of them seem to be called "the sheep and the lambs" or "two ducks" or "the sick calf" or something equally agricultural and Welsh-sounding. Breton is Welsh with French polish, as far as I can tell.
But it wasn't all math and tables and drawing little arrow markings on tide vectors and talking about how to avoid shooting rescue helicopters with SOLAS-grade flares. Some of it was about seeing very pretty seascapes emerging from various forms of French precipitation.

This is the small island of Houat. It is pronounced "What". Bilingual hilarity ensues.
Some of it was anchoring under motor and under sail. That's an anchoring dayshape, a.k.a. "an anchoring ball". The fishing boats, which are usually in sight, have a full set of shapes they display to indicate what they're up to, and, by inference, what they can be expected to do next. Regarding the anchoring ball, iIn 15 years, I've seen one exactly once on Lake Ontario. There's no cops for this sort of thing to my knowledge (although if you screw up and haven't displayed the right shapes or light, etc., there may be lawyers). It's just a case of learning best practices.

More Houat, during a lunch stop. It kicked up past 20 knots during a delightful repast here, making for a good run.
French weather is pretty English (i.e. charitably described as "changeable" and less so at "barely predictable despite the locals having basically invented meteorology") in its moods and rapid cycling. A bit like the tides, really.

One of these is probably Hoëdic, Breton for "isolated danger mark". Note the untouristy weather.
Nonetheless, despite the educational challenges and a spot of condensation in the V-berth that just wouldn't dry, the sailing continued after an interesting, misty approach to Port du Crouesty (where skipper Dave stretched his legs in search of crusty French bread and we drank at a bar called Cape Horn...arr...), the weather improved.

Note the liferaft: This "RYA Training Centre" is equipped forproper ocean travel, even if the Bay is a rather cozy corner of the Atlantic...it could get nasty quickly.
Quite a bit, really. A very high pressure system (1032-1042 mb) had isobars steep enough to bring the occasional hatful of wind, something fairly unusual in my experience over continental North America, where high pressure usually means "calm to angel-fart zephyrs" and "get out the assymmetrical". Anyway, we always had enough wind, even at night, to move the boat.

Pretty benign for November. Temp: about 10C
After ceaseless MOB drills involved a weighted fender named Bob, we timed the tide to enter the Golfe du Morbihan for more ceaseless MOB drills. Both John and myself eventually improved, even if it was akin to driving nails made of butter to achieve a semi-timely "save". "Man overboard, point, heave to, throw something floaty to poor Bob, start motor..." I have dreamt these lines since my return. Thanks, Dave...sort of...

Weirdly, the Golfe resembles parts of Georgian Bay, perhaps 500 years in the future and littered avec chateaux.
We had some fun in the Golfe. The tidal streams inside it are delayed about two hours from the Bay "outside" and you can have the interesting sensation of seeing four knots from the speedo and 10 knots on the GPS when it's in your favour.

A visual cliche, to be sure, but it was followed by a proper thirty-knot line squall. I like helming in proper line squalls.
We returned by sea and a sort of canal-like approach to the medium-sized town of Vannes, which had an impressive number of decent restaurants and plenty of little French kids rowing down the middle of the channel. My Fox 40, a whistle unfamiliar to skipper Dave, came in handy.

The Bristol Cutter Cariad, the sort of working boat that would guide bigger vessels through appalling weather we didn't really see.

No time to step aboard and explore, alas. Like Carnac, so close and yet...
We covered off various boat-handling techniques, such as the useful "spring off the dock" stern line to midships dock bollard method, and I gained a new respect for the concept of looping docklines around door-handle type cleats, as opposed to tying off, but that's a separate post.

The end of the story is only a little sad. Nick the anecdote-stuffed RYA examiner came aboard and we presented elaborate (to me) passage plans to get us not only into three of the local Bay of Quiberon ports we'd already seen, but to cover a 100 NM passage involving (at a posited five knots of boat speed) various tidal and weather conditions, as of the day of the exam. After submitting these plans and after significant ex tempore talk on safety, weather, what three blinks in the fog might mean, and other nautical minutiae, and after approximately nine hours (I'm not joking) of examination, John achieved his Yachtmaster Coastal certification.

Long story short, I got into skinny water (but didn't touch, at least) on the wrong side of a green buoy the size of a Liberty Village condo and failed the exam. Fatigue and the distinct sense of my serious underpreparedness foiled my concentration, but I don't regret the attempt and feel I got plenty of value and instruction of the experience.

Now I have a better sense not only of what's involved, but where my weak spots are (I HAVE to get out on deck more and let the missus drive...which she has resisted, but should not). I found the quality of Dave the 'prepper' and Nick the examiner to be exemplary, and would encourage anyone wishing to try for this sort of certification to consider choosing Sailing School Brittany for top-flight instruction on a well-found vessel.

While I let myself down a bit (and part of that arose from a very compressed work schedule in the run-up), I cannot in any sense fault either the coursework or the instructors' delivery of it. Well, maybe a bit more weather theory might be an idea, but that's a very small cavil. I've received no price break or footrubs for the above sincere endorsement; I really believe it was full value for the price and a real-world chance to review the holes in my seamanship canvas, so to speak.

That's the new Jeanneau Sun Fast 3600  rafted up to Tamara in Vannes. France showed us an unbelievable volume of boats, several of the "super hot" variety. Also of note are the greater number of fenders called for when tidal current is about and who knows how many boats may raft onto one's boat.
I haven't even discussed the superb boat provisioning/catering, which was by Alison, a former pro in the field, and was superb. So despite "unfavourable conditions and unlooked for outcome", I am likely to return, better prepared, and better studied, and I think I'll nail it next go round.

It's all a matter of achieving the right balance.

Gone sailing; back soon.

'Allo, 'allo.
 A man's got to know his limits, if only to give them a push now and then.

Like Wales run by the French
More when I return in a couple of weeks.

UPDATE 13.11.20: Back from an educational time, but swamped with work. Will post some lessons learned in a week or so. Boating ain't cheap.

Slick or sleet: The horrors of Haulout 2013

While this was taken on November 1, a day later than Hallowe'en, it illustrates how even a "moderate" gale of 40 knots or so can create havoc in the channel just outside of my club's basin. Conditions like this are not particularly rare.
Photo copyright Eric Jacob.
What could be more appropriate for an October 31st post than to list the horrors of hauling out? As I write, there's a warning of a 45-knot (gusting 60) gale that's supposed to lash Toronto while I am herding a bunch of Halloweenies on a search for sugar. And I still have a boat in the water.
But first, the equally windy tale of the boat that is not still afloat.

Every baby needs a cradle.
Usually, I am driving a safety boat over the two days of my club's launch and haulout process. This year, some welcome work meant that while I could test a new foul-weather jacket under real-life conditions (it passed with high marks), I would not be able to actually be on station for the Saturday haulout. So my wife and I put the cradle up (above), brought the boat over to the seawall, and I wished her well with a 0700 h call (still mostly dark at 0700) in increasing wind and rain.



Funny, this worked in the spring...
First bit of horror came with the realization that the former sling marks (see red tape on top pipe rail) have altered, no doubt because the new engine and gear aboard has shifted the center of gravity. Mrs. Alchemy was called over to  consult.


No one looks happy, a bit of a theme in a cold gale.

 Eventually, air got under the boat...

This will change yet again when I shift that load of lead "trim" out of the bow.

Note the "cinch belt" keeping the slings from sliding around and terrifying the villagers.
Once down, it was clear that staying mostly still at a dock does the bottom paint no favours.

Ew.
On the upside, with a number of the larger boats (ours is a large boat, but has never been among the club's larger boats) off to winter digs featuring a TraveLift, there's some welcome space between the boats and I don't have to put the ladder off the stern.

Most of this will in fact dry up and flake off. Or I will fix the power washer which has blown a gasket.
A rare, if semi-obstructed, side view of Alchemy. The paint job's holding up thanks to Mrs. A's summer two-part touch-ups.
What big fenders you've got!
 So as the weather got worse...
And out of focus.
...and worse...
Not present...the 20 foot surge over the end of the runway at Future Boat Club Killer Airport.
 ...the decision to defer the small boat retrieval out of the Western Gap until a calmer Sunday was taken, and a sodden but successful Mrs. Alchemy splashed home before hypothermia took hold.


Whoops. Time for a brushdown.
The boat bottom is surprisingly mucky, as is the prop. I will apply some elbow grease to see if this is, as I suspect, superficial fouling. 


Dermabrasion, steel boat style
Meanwhile, the Old Girl is still afloat. I'm scheduled to haul out for Valiente's winter storage at the redoubtable Uli's Pier 35 on Sunday afternoon, but the above-noted gale tonight and tomorrow argued for some seamanlike prudence in the form of lashing and doubled dock lines.
Boom lashed, tiller lashed, bimini lashed and boom pointed at direction of gale.
After a pump-out of the existing rain and some lashing of the bimini frame and tiller, I checked the state of charge of the batteries (100%) if the bilge pump needs to work while the power is down (or the power cord is worked loose). I know from experience that water WILL sluice down the mast, particularly from the expected SW direction of the gusty weather.

Bow lines doubled.
Doubled springs and stern lines and reposition big ol' fenders.
Midship spring and doubled bow lines to port.

We'll see if she's still there on Sunday. I would think so.
So while I didn't have the time for a late-season sail, my boat partner Clive did, and apparently enjoyed himself.  I'll keep my fingers crossed that the boat will be undamaged when I return on Sunday and that the Hallowe'en Gale is more treat than trick.

Not seen: the actual sailboat sailing in the south-eastern part of the harbour. Looked nice.
UPDATE: November 3, 2013: Aside from the climatic dice-rolling that saw the overnight temperature in Valiente's cabin dip to 0.2C, the lake did not seize and Sunday was bright and only faintly breezy. A good day to redline the engine (based on some possibly fictional idea of "blowing out the carbon/oiling the rings, etc.) and get to Valiente's winter quarters for the 40th time.



Behold a rare video, taken by boat partner Clive. It is very boring, except for the fact that it demonstrates how slowly one should move when tugging four and half tons of sloop.

Blurry because it was very much dusk at this point. She's pointed more or less into the wind for a change.
After some intense and Clive-aided cradle assembly, Honda genset-running and sling-positioning, and a measure of the usual standing around and waiting in the surprisingly busy confines of Pier 35, the old girl was hauled without incident, rapidly winterized in engine and bilges, and will be visited in a few weeks for further lashing and prep. Despite a degree of under-utilization this season, which was predictable due to various workloads and external events, she had a good summer, and the new standing rigging is keeping the mast up and the sails pulling.

The real sea monsters


The good ship Alchemy does not feature, as do many recreational sailing vessels of her dimensions, a multiplicity of perforations in her hull. This is due to the perspicacity of the original owner and the designer: I had nothing to do with the cleverness, except that I appreciate fewer holes in boats for reasons less obvious than "less likely to sink".

Hey, two centimetres is still above the waterline, right? Dubious to me, but very common on all sorts of vessels.

As said, she does not have a whack of thru-hulls. Below the waterline, there is one "innie" in the form of a standpipe and two "outies", the head sink drain and the galley drain. This is not the usual state of affairs on boats.
This is from an Ericson 38: Too close together for my taste, although the rationale was probably "this is the only place one can reach".
This is, as depicted below. Everything that needs a drain or an inlet gets its own hole in the boat, some above but quite a few, alarmingly, below. I have changed a couple of seacocks in the water by plugging them from below, replacing the seacock, and knocking out the plug with a length of dowelling. It's never been a dry or soothing task.
A sea chest on a fishing boat: The idea is to have single valved hole in the hull from which several valves for various needs (engine cooling, washdown, keeping fish in a box alive) may be drawn. One hole in means just one hole to plug if things get over-damp. Missing: a softwood or rubbery plug on a string.
But there are options. Behold, above, the sea chest. This is a venerable sort of below the waterline grated box that allows in a controlled fashion outside (hence "sea") water to be made available for engine cooling, the flushing of heads, fire hoses, etc. The above model on a relatively small vessel is, in my experience, not the usual setup.
Proper thruhulls screw to seacock with flanged bases, which in turn are bolted to glassed in pads. (c) crusingonstrider.us

This is. Individual thru hull fittings screwed into seacocks, a nautical term for a bronze, brass or plastic valve, which is closed by (typically) a quarter-turn of its handle.

The usual choices made on modern yachts (and "1988" denotes a modern yacht, just not a particularly current one) is to punch a hole in the hull where needed, to insert an appropriate bronze or pretend-bronze or plastic thru-hull, and to top it with a bronze or plastic seacock, a sort of valve with a handle. This is to address the irony that while a boat is meant to float in the sea, there are many reasons to bring controlled amounts of the sea or the lake into the boat.

Such reasons include the cooling circuit of the diesel, either in the "raw" form, where sea water is sucked through the engine by means of an engine-driven impeller, or in the confusingly named "freshwater cooling", where the seawater is used in something called a heat exchanger (a sort of radiator) to transfer the engine's excess heat from a closed and pressurized circulation of antifreeze to the sucked-from-outside seawater, which is then propelled out of the boat with the pressurized exhaust gases. It's a generally robust system, even if the glycol mix in the sealed engine circuit isn't really "freshwater" at all.  The point of the glycol is twofold: Firstly, antifreeze, "Dex" or glycol is more effective at absorbing and yielding up the waste heat of the engine than is straight water. Secondly, it is less corrosive than fresh water (in terms of engine metals) and quite a bit less corrosive than seawater, which yields its salts and other crud-making substances at the relatively low temperature of 155F or so. If a diesel has to work inside a watery jacket, it manifestly prefers that jacket to be under boiling temperature, but not much...175F to 190F is typical.

S/V Alchemy's easily accessed standpipe withT-fittings for head, engine and A/C, plus a spare for saltwater supply to the galley. Also seen are the fuel tank manifold/valves to the right.

You may consider the following depending on the layout of your boat: a standpipe. Above is the one on Alchemy. It's essentially a vertical seachest, with the important distinction that the top of it is customarily well enough above the waterline of the boat to permit service and cleaning...without hauling the whole hull out of the water, or, conversely, going to a place with impressive tidal ranges.
Super-duper standpipe (c) setsail.com/Steve Dashew. This shows the strainer elements close to the pipe, plus a similar "cap" as to Alchemy's.

A standpipe is a straight metal pipe either welded directly to the hulll or screwed onto a thru-hull base. It can be secured by bracing if needed. As noted, it extends above the waterline and is capped with a gasketed (again, usually metal) cap. It resembles the old style oil fill tubes on the sides of North American houses from when oil was a common furnace fuel.


Down the pipe, below the waterline, are welded-on T-fittings threaded to take sea cocks. Put in as many as are required and can safety fit in regards to access.
The standard approach, but who wants to dive under the boat to remove a couple of screws?

The advantages are many in that you have only one "intake" hole in the boat. Fitted with a hinged screen or filter, you can, should you suck in fish and/or debris, open the top cap, see what's down there, and use a length of dowelling or a small-calibre weapon to clear the entire standpipe.
Getting there, but you still have to dive on the boat. Why not a heavy spring on that little door? It's a plot by skin divers.
An alternative, "belt and suspenders" approach would be to have a single, large seacock near the centerline/midpoint of the boat (to ensure it is always below the waterline, even on points of significant heel). Then, you could tap an appropriate pipe with the required T-fitting and smaller seacocks for raw water intake, A/C, seawater domestic supply, and head, and fit it to the seacock. Then, if a T-fitting fails, you can shut off the main seacock and fix it (or reroute its hose to a spare fitting) while underway.

There is no particular reason that the seawater intake must be forward of the engine, other than that forward is usually deeper in the water and less likely to be above the waterline or in agitated, bubble-filled water if the boat is heeled sufficiently. Getting "gulps" of air in the raw-water intake circuit could indeed lead to problems, so you have to figure out the angles. Generally, making the lowermost T-fitting on a well-placed standpipe the engine cooling feed would do the trick.

As for positioning, you can "hide" in under saloon stairs or inside a piece of galley cabinetry, just as long as you can reach all those seacocks/shut-off valves and can look down the standpipe to both see blockages and deal with them.

The standpipe in my steel motorsailer saved my engine when I noticed the engine temperature rising despite the proper functioning of the engine pump. I shut down the motor, looked down the standpipe and saw that we had sucked in a large, thin plastic bag obligingly occluding the raw water intake.  I was able to push it down and out with a stick designated for this purpose, and we resumed motoring with no further incident. 

Typical, but no good for steel without some way to keep the metals apart.

Some methods of stopping this sort of thing happening are above; most sailboats have a simple brass strainer of the type pictured. Others have rather more massive perforated grates for sea chests.

Arr, that'll keep ye out, Squiddy. (C) www.sbmar.com

Many folk are aware that a bag or a particularly gnarly weed or even small creature will get munched in the engine's water pump, which contains a fast-moving impeller capable of Cuisinart-like execution. To keep macerated "bits" out of the surprisingly delicate engine cooling passages, however, a further measure is needed:

Increasingly common on boats "pre-engine" and "post-impeller", this basket filter can save your engine if you suck in a bag or a significant amount of sealife or vegetation. (C) Colin Speedie
I have one of these on the plastic sloop, and have removed plant and animal life that would have otherwise entered the engine to no good end.

A relatively common sight on boats is the bronze raw water strainer. Here's Groco's factory-fresh version:
The Groco model. Aside from plastic versions made by Vetus et al that resemble coffee basket filters, Perko and Groco seem to have the market cornered.
Mine is made by the Perko company. There's not a lot of difference, except the Perko unit seems to me to be more sturdy and better physically supported. As part of the endless reengination process, I've had to service mine to maximize its critter capture qualities. First came a wash of the heavy acrylic housing.

This was opaque with greenish residue before a hearty soap-n-swill.
Then came the removal of some old, dry seaweed. The system works!
The filter works as advertised. Even in Lake Ontario, sea muck abounds.

I gave a light scour to the brass parts. It doesn't have to look like a Viking's tankard.
Don't expect that hatch floor to get cleaned. It's headed for the bin.
 And then back onto the backing board that bolts to the engine room's forward bulkhead:
I'll leave the Brasso rub for another time.

The fly in the ointment of all this wonderful diesel-aiding cooling process and planning and design is, like the fly itself, an invertebrate. And, without being overly dramatic, it may pose a greater threat to cruising than world economic collapse, rampant yacht piracy or even nautical zombies.

This is what's left when you gobble the top three tiers of the ocean environment.
I'm talking about jellyfish. The New York Times says they are taking over, and while I was aware that they (and a few other oceanic nasties) were taking advantage of human rapacity of their predators to breed like, well, jellyfish, I hadn't realized the extent of the problem.

Most of us, outside of certain Pacific island nations and Australia, where most of the wildlife seems bent on killing the inhabitants, likely do not consider the humble jelly, a varied and diffuse collection of species that have been doing their glutinous thing since the Cambrian era, a significant threat to human safety, or, Neptune forbid, the cruising lifestyle. Most of us would be mistaken.

No matter how downtown you think you are, do not place on genitals.
Here's the issue: the jellies are taking over because we've eaten a large percentage of what eats them.  Needless to say, this has implications for the overall health of the oceans, which some folk already believe is deeply compromised, and implications for little boats that wish to, say, motor through the doldrums.
We're gonna need a bigger filter.
Now, as humans, once we identify a problem, even the problems we can clearly originate in our own actions as a species, we tend to have solutions, some brighter than others. Or at least more stabby.




And who's to say our time-honoured traditions of eating our problems won't help here? But you can't catch everything, and as a person who wishes to dive coral reefs in the Pacific, I have to wonder about what's not eating this little fellow, and did he bring his friends? And, having turned the oceans into nutrient-free lubricant, will they find a way to leave Earth?
One wonders what the standpipes on Enterprise are like? Nice bits of kit, one hopes.

The future of "it's what's for dinner".
So the problem of jellyfish jamming up the cooling circuit occupies my mind. I may have to modify an existing strainer for the standpipe so that if I ever "inhale" some little deadly creature parts, I can use some sort of nautical Q-Tip to ream out the pipe and send it far away from my beloved diesel.

Oh, and we need to eat these buggers, too. And these excitable bastards. Along with rapacious fishing practices and a general curtailment of human population, of course. I like to think I'm fair.

But not when it comes to the cooling circuit? No compromises.
