Pat, the storage locker was intentionaly left with a gap so water would pass. No floatation. I did a quick displacement calc, and these will hold gobs. I thought about putting a lattice or slat floor in the bottom and maybe a sliding tray in the top. You could be sitting in the bench seat and lift the seat lid for access to open boxes of flys and other paraphanalia, and simply close the lid for uncluttered fishing. I had also been thinking what to do with the anchor lines, so I may have net bags inside the locker so the wet line does not get tangled with battery cables, etc. This stuff may be something that is added later.
