Sticking around

That big radome doesn't look so big up there and seems like it won't interfere with the sails when tacking. That rescue hook is not part of our rig, but of our dock.
When I last posted, it was about an unexpected day-long power outage during which our frozen and refrigerated food was saved by a portable generator. Today's post is about the extensive modification of the mast prior to putting it in, or, in the case of our deck-stepped mast in its tabernacle, on Alchemy. Said extensive modification involved the running of four lengths of wire (two 1/2" thick LMR-400-UF cables for AIS and VHF antennas, one 18 mm Furuno radar cable and one 1/4" UHF-style GPS cable). This proved to be...tricksy.
In order to get a greater bearing surface for the AIS antenna mount, I added a bit of scrap teak to an existing teak pad on the spreader. Saved drilling fresh holes in said spreader.
The prior RG-58 VHF cable was inside a cable-tied length of nasty foam pipe insulation, along with several 14 ga. wires for the various mast-mounted (and now LED) lights. So while I could clip the PL-259 connector from one end and pull the cable out of that half-assed loom (presumably to reduce mast noise and halyard abrasion/fouling, but a pain in the ass for us), I could not use it to "fish" new cable. In addition, the new cables, save for the wee GPS run (which is part of the Vesper XB-8000 package) were considerably bulkier than is customary on Lake Ontario, because they transmit more power to the antenna with less signal loss, a worthy ambition for the prospective offshore sailboat. So that meant cutting holes in the mast large enough to get them in.

Five screws, tidy heat shrinking and no sharp radius. Should work well.
So I had to get inventive. In my garage of Too Many Boat Things, I found the 1/4"(6 mm) forestay to Valiente I had removed in 2013 when I rerigged. I cut off the terminals and I had abour 40 feet/12 metres of reasonably stiff wire. I drilled the VHF hole in the top plate of the mast between the sheaves and, with the coax taped to one end of the forestay wire, carefully pushed it down the mast. Carefully, indeed, because it's a busy area in there and I did not wish to foul halyards or that grubby, if still functional, foam loom of 14 ga. wire.
This is the Scanstrut LMM-2 gimballing radome mount. It's pretty slick, but I had to be careful to get it centered and rivited correctly.
After I learned I could spin the stay to get it past obstacles, the work went slowly, if productively. Together with Mrs. Alchemy, we fished the four wires to the appropriate mast-base exits. After that, it was time to do the radar mount.
A total of 12 3/8" pop rivets are holding this on. Feels pretty permanent to me.
This was mostly just careful work and following the IKEA-like instructions from Scanstrut. Then the usual routine of inking the right spots, using a  nail punch and hammer, followed by the use of a small drill bit and then a larger drill bit, and then the riveting. It took about three hours.
The Vesper AIS's GPS receiver is mounted on the same gimbal as the radome, nice and high.
May we never heel or pitch-pole this much! But I'm ready if we do.
Loads of crimping, chafe-guarding and tidying up later, we moved the mast to the Place of Hoisting.
Two of the delays in getting the mast in were the realization that Alchemy was pointing in the wrong direction and that the mast had to be craned on its "back"
Because I have so many stays and shrouds and must mount rather exactly into the tabernacle, the crane activity can take longer than the allotted 30 minutes per boat, and it's to the credit of my friends who helped me that certain slowdowns (like the inability to retrieve the hoisting line) were dealt with in such a patient way. I need to tell the crane operator I'm going to need an hour next time.
Alchemy unbound: waiting for my turn.
Some frustration, followed by a round of beverages purchased to mitigate frustration, later, Alchemy was back at her dock with shrouds and stays provisionally tensioned....which reminds me, I need one of these.
Nice! Got the full-length battens in unassisted this year, which is always a little tricky.
So the jib and staysail are now in place, as well as the rather good-looking mainsail pictured above. I declare the season underway.  The next steps will be drilling fresh holes in the pilothouse in order to route all those cables to their new devices.
