Hi Folks,
I was thinking about the problem of sheathing a boat's waterline for ice protection and winter afloat, and I realized I really had not come across any references on how to do that to a smaller boat, carvel planked, which may only have 3/4" planking.
Lets assume what we want to do is go all the way, because we are crazy. We want to sheathe the whole bottom, all the way to 6" above the waterline of a smaller sailboat (say 25 - 30 feet) with something like 3/4" black locust to protect against ice and other sorts of damage.
My first inclination would be to do it like double planking. Apply 'double planking goop' and canvas over the carvel, then fasten the boards with round headed screws from the inside of the boat. with 1/2" of bite into the outer planking, and using non tapered screws, shouldn't that be enough grab to hold em on? Perhaps if I also had four 'through trunnels' per plank. Probably don't need that though...
Any advice or experience with something like this?
