I am planning to install tie down points with 1” webbing, gflex and fiberglass, on a Wenonah ultralight canoe. These points will tie down packs, camping gear and air bags. My question is whether, for strength, to install these on areas where there is a foam core underneath, on areas where there is not foam core underneath, or does it matter? Also, is the center area of the hull better/stronger than the chines area or the tumblehome area? Are the rib areas a good place for them? Would the areas with foam underneath have chance of delaminating under stress?
This summer, I plan some extensive practice time overturning the canoe and reentry, etc. I like tying in gear and would prefer not to debate that. These tie down points will see some significant stress keeping heavy packs in place, etc., and so I want to locate them in the strongest areas possible. Your collective thoughts would be much appreciated. Thanks.
