Im going to be building a flush deck up front. I need to install some cleats about 5/8 from the top of the hull. What material do yall reccommend? I was thinking of the 3/4" pvc trim boards. I could peanut butter them to the sides and secure with stainless screws and never have to worry about rotting. The deck will have 2 bulk heads underneath it, and I also plan on filling the entire cavity underneath it with foam. but I need something sturdy for the edges since I wont be able to tab underneath it.
