one of my bunk boards broke the other day, and i am having a problem finding a replacement. the current boards are 3"x 7"x 11' (not sure what wood, but looks like oak) mounted upright on an angle. I am thinking about using two pine 2'x8's screwed together, but wanted some opinions. The boat weighs about 5500lbs, what do y'all think, will the 2 pine boards be strong enough? Any and all advice is appreciated.
