[QUOTE="onthewater102, post: 401824, member: 13702"] ^^^^ Exactly. Be sure to plan on drainage for the decking if it's backed by poured foam. I didn't plan for enough of this in my build & now I have to go back in & figure out how to get rainwater to the bilge in the rear efficiently. My current drains take too long and are prone to clogging. I ran vinyl hosing under the support ribs but was limited to 3/8" hosing & this has not been enough volume to drain the deck area between the benches. I'm still looking into options, but the more I think about it the more I don't want to think about how much I'm going to have to tear apart to fix it. After looking into PVC drains built into fiberglass boats I'm seeing manufacturers using no smaller than 1.5" pipe - likely due to avoid debris clogging the pipe. [/QUOTE]
