Wadanoli, I've moved your post to this forum. The other forum is for questions about the forum.
As to fender
boards. MY understanding of fender boards, and how I have mine set up, (for your size boat
too) is that I have a 12' long 2 x 8. I've drilled two holes near each end of the board, about 4 inches apart and at a 45 degree angle to the plane of the 8" side. those two holes meet on the OUTSIDE edge (8" ). I've sorta countersunk those so the deploying line won't rub against what you are tied up to.
The FENDERS, go between your boat
and the fenderboard - as many and of a sufficient size you need to keep the board away from your hull
as the boat (fenderboard) moves against the pilings. So, I'm not really sure what your question is - can you be more specific?
