Thanks for the tip on the Futa. Might have to score one of those.
Maybe not right on topic, but maybe using those noodley things in the bow behind the bulkhead? I have flotation up front that seems to help when the boat is submerged.
But hey, at least having some float bags is good. I have run across a few boats foundering in the water with nothing and they are miserable to haul. So a word to beginning boaters out there - fill up the space!
