Ok I have made the repair. This is a 6 canoe trailer that I converted to a jon boat trailer. The boat sits on 2 treated 4x4s. I ended up topping the wood with a pvc moulding called Azek. It is 3/4x3 1/2 x 8. Fits over the wood perfectly. Holy cow guys... sure glad for the pvc recommendations. That boat slides on and off with little effort.

SeaRay, I see why the bow strap is a critical factor
