    BlueBell Ahhhhh...

    How about less sail area.

    No, you're going to add to the hulls.

    No, I've never done it before.

    Good luck, let us know how it works out.

    Cheers

    I've considered doing this before.
    But I just wanted to increase the buoyancy of an ama, so the foam would have been constant depth.
    I think you can do it, but I would be concerned about getting the foam to taper properly.
    How much length would you taper the foam over?
    Perhaps you could think of gluing tapered foam on the boat, like you were strip planking.
    How would you hold it down? What is the construction of the current hulls? Vacumn? Staples? On kayaks (strip planked) the designer suggests holding small items in place with superglue. Don't know how that would work with full strips. Typically supper-glue is waterproof, but that would be a lot of glue - expensive I assume.
    If you are going to use epoxy, don't use mat.

    Please post some photos, and dimensions of the boat. Wine glassed sterns on a cat? Can you provide a rationale?
    I'd fill them in - except I don't know what I'm talking about - photo's again?
    You probably ought to estimate the increased weight vs the increased buoyancy.
