Default fiberglass layer rule of thumb

just can't remember what material and number of layer we have to use for lets say, stringer replacement and transom ?

1708 mat x 2 or 3 then 1 roving for 1 layer ?

3 layer 1708 you're all set. you can add an outer layer of chop or roving if you're planning on smoothing bilge out, the chop and roving will sand easier smoother than the 1708. good luck. fun job

I added a couple 3" tall stringers between the main stringers in the bilge to stiffen up the back part of the hull.

engine stringers

3 x 1708 with an extra layer or two of tabbing to really make it bomber. Dont bother with roving or mat if your looking to get a leg up on final finish toss a layer of peel ply on at the end.


similar to this but three over the stringer and an extra tab or two, i also put one layer down underneath to tie it all together in a sort of a T box that fully encapsulates the stringer

thanks . . . heres the transom layup.


i haven't worked on the book in a while. I am up to almost twenty chapters but am trying to figure out how to format it and what to do with it. . . . . some day

I dont bed transoms in ounce and a half anymore, i use a core bedding compound instead. Way better and way easier to work with.
