  2. Re: Cedar Strip boat hull - Fiberglass sheathing or not?

    If the cracking is minimal, it's probably worth a try. If it continues to be an annoyance or you plan to get a lot of abrasion it wouldn't be too tough to sand it off later and add a layer or two of...
  3. Re: Cedar Strip boat hull - Fiberglass sheathing or not?

    First of all, lose the concept of "Epoxy Paint". Paint isn't epoxy, and epoxy isn't paint. "Epoxy Paint" is primarily marketing hype to make people believe that the paint they are buying is tougher...

    Whether you can or can't eliminate some form of sheathing will depend on how the plank seams are done. Something has to prevent water from coming in between the planks. There are boats (like...

    Which Micmac? The 17'x34" and 18'x 36" glide noticeably better than the 16'x34" version, and the 18' x34" version is probably faster than the 18' x36" unless you load a bunch of gear into it.

    Seven ounce cloth is pushing it a bit for a sail that size. Granted, on a gaff sail the yard's weight prevents the sail from needing to "fly" free up high, but still, weight aloft is weight aloft and...
