This is a little stainless steel piece I had to cut to fit around and hold the hex head of the leeboard bolt. This keeps it from spinning when I tighten down the leeboard. This is the only way I can tighten the leeboard enough so that it is able to hold in place with a reasonable amount of force against it. Note also that rather than use an underseat bracket as in Gary's book, Gary recommended I try simply stiffening the whole side with a piece of timber and mounting through that. Much simpler solution.
Sure it is a simpler solution, but I don't know if it will prevent the side of the hull from bending when the leeboard is forcing it.Your timber will bend too, exception made if you use huge thickness, but in this case you will have a heavier structure.
ReplyDeleteI am just facing this moment right now, this is one of the few steps I still need to do in order to launch my wa'apa.
I think the bracket that put together the side of the hull and the bottom of the sit it's extremely important to avoid weird forces to act on the side panel of the hull.
Did you talk to gary about that?
But anyway, congrats for her! she is looking beautifull!
I too have that little nagging question in my head. I had it about the underseat bracket in Gary's book too. At the end of the day, I just don't know. I've never sailed before and so I'm unfamiliar with just what kinds of forces are going to be present on that leeboard. I can guess. But that's about all I'm doing. However, the timber piece, rather than the bracket was suggested by Gary. He said that he originally wanted the forces transferred to the seat, but later found that just a vertical stiffener was adequate. Just FYI, that piece of timber is both epoxied and screwed into place via 8 evenly spaced screws. Also the timber piece is 70mm x 19mm and goes from gunwale to chine.
Deletedid it your way!
DeleteNice. Post some pix when you get the chance. Note too that also per Gary's suggestion, I mounted a second vertical piece 300mm foreward of the main one under the seat. This second one gives me a second location to mount the leeboard, giving me overall greater flexibility with the CLR. Not a necessity, but easy enough when you're not building a bracket for it.
DeleteHeading back into the bush with no internet in a couple days. Will be unable to view pix posted online till sometime in March after we take Shan Skailyn on it's maiden voyage from Saidor to Madang.
Good to know that you have gary's advise. I will consider that suggestion. Mainly because it will be awkward to work under the sit.
