Don't judge me. I'm completely new to this. This is just a thought.
I'm refurbishing a Supercat 17 , and prepping the mast so that water cannot get into it. Would it be a stupid idea to fill it full of foam packing peanuts so as to displace any water that could possibly get in if it did? They weigh almost nothing and would allow drainage.
Dumb idea?
