No I don't think I will be able to make that work. I would need to make the well,gantry and part of the deck removable,a lot of ways for me to mess it up and lot of places for water to get in. I think I will stick to gluing the whole thing down tight. This means getting it right first time.
Speaking of getting things right what is the opinion on battery charging? A charging socket on the boat or just remove them to charge?
