Daggerboard measurements and repair

Post by Mookie » Tue Apr 21, 2020 12:22 pm

Hello all, I’ve pulled my sticky daggerboard and searched the forum for answers and gotten bits and pieces of answers, but still have some questions. How do you repair daggerboard skins, and are there templates? I can’t find them anywhere.

My daggerboard’s fiberglass skin has separated for the top third of the board and causes it to really stick when full down. Who has made this repair, and how did you do it? Drilling and injecting epoxy would be relatively easy but won’t restore the profile, and clamping might not either. I can cut the skins off, but where to go from there? Reattach the old skins, or glass new?

Any first hand experience with this would be fantastic. Thanks!

See the class rules, appendix B for the template

I vote for re-glassing

Aha! There it is. Thank you AJ.

Re-glassing is certainly the right way to do it, and I don't mind doing it, but I was worried about getting the right finished dimensions again. This daggerboard info should do it.

Is it possible to make a template from these dimensions? If so, how's it done? How would I plot the leading edge radii?

Thank you.

Yes, I'm thinking about compukeel. In the meantime I lifted a template off a fair section of the keel per West Systems. I'll check it against the class measurements and see where we are.

I have a catia file with the template shape.
I used it to check the shape of mine when I bought the boat.
Do you have access to any kind of cad software?
I can export the file and send it to you.

Thanks Sam, I will find out and hopefully take you up on that.

In the meantime, I have photos of the daggerboard coming out of the boat, the template, and DeLand and skin removal. If anyone is interested I'll post them here if you tell me how to do it. Currently they are being rejected.
