Pictures taken, need to resize, upload, yada yada. Takes time and effort, and worth a new thread on #497.
In the meantime I can report that I mounted the one-piece mast on the new boat, just lifted it and put it thru the partners, brute force. Was nowhere near as hard as I thought it would be. Of course, I'm pretty big (6'1"), so that helps.
All I had to do was spread my grip as much as possible on the mast, get up on the cuddy, lift the mast, lower the butt to the ground, then lift it straight up and into the partners. Actually, the only real hard part was getting myself up onto the cuddy, being a big guy also means that I'm just about heavy enough to dent the cuddy top when I stand on it. I'm going to try this again but standing on the foredeck, facing aft. And there were two other "hard parts"... When I first lifted the mast, the butt landed on the cuddy by my feet, I had to drag it over to the partners. Right now, the gelcoat is a mess, so who cares, but for future I'd rather not scratch the cuddy top. I'm thinking of laying down a cut-up yoga mat as a "landing pad" for the mast, temporarily of course, keep things from sliding around. The other issue is that I thought the mast butt had nicely landed on the mast jack, but once I looked I saw that it had landed about 8 inches aft. So I had to worm my way under the cuddy (always a pain) and lift the mast butt over to the pin. There's got to be a better way! I'm thinking that a small post from the partners to the keelson would help guide the mast onto the mast-jack. I may even grind off a vertical "slice" of my old compression post (from #37) and use that. We shall see. @GL, does your hinged mast sleeve help "aim" the mast down onto the mast-jack?
In other news, after stepping the mast but before re-attaching the stays, I stepped aft in the cockpit to hop off the boat (remember, she's up on her trailer). Completely forgot that I hadn't put a support block under the trailer, so of course it tipped over backwards as I hopped off... Wham! Transom hit the dirt, then boat/trailer tipped back forward and landed on the trailer tongue... and the mast went boing-boing-boing, and.... nothing. All was well. I don't plan to repeat that performance, but nice to know that the mast is quite secure once it's stepped, even if/when it's not properly stayed. I wouldn't bet on it if the BOOM was on the mast, but naked, just the mast - no problem!
OK, that's my usual over-wordy brain dump, I learned a lot about #497 yesterday. Of course, since I was doing all this in my front yard, my neighbors were sure I had lost my mind and came over to check on me. Fortunately, my wife was at work, so wasn't around to say YUP!
