Agree with Hoyt. For me the disruption to stop sailing to pull the board up to clear weed or trash would outweigh any hydrodynamic benefits. I...
Is that bulkhead supporting your mast? If so you probably need a rigorous design check to ensure the rigging loads don't exceed the material...
Kia Ora I would examine a waka you like the design of to understand its weight, lines and construction. From there you can do some basic reverse...

I'm curious if it would be feasible to flange the existing mold and then lay up a new bow mold section over a partial plug to the desired shape?
Which is most extremely observed with comparison between a monohull and multi.. @DC, I'm enjoying following your build, very inspiring
My understanding below and very happy to be corrected... A low cp hull has less volume in the ends and more amidships. At a velocity where the...
Philip, do you have some drawings or photos of your sailboat? There is probably a very practical solution available to get her pointing nicely.
Interesting thread. All hulls have a speed at which they can be most efficient, all the resistance elements then scale to various powers of the...

Agree above is simple and quick. To laminate any frame straight and true you will need to build a jig first. Cutting tube ends to splice nicely...
You could cut down a used sailboard mast. Choose the end that has the flexibility characteristics you want.
That sail looks like it was cut for a standard round mast. Once you have vang tension on a 3.7, the mast bend is fairly even (and well more than...
A couple of observations and experiences based on my own square top main sail. This was re-cut from an older sail so not an ideal starting point...
