You might find that a fore and aft baitwell access might work better. If you used heavy enough plexiglass for the lids you'd still be able to sit on it. Also with 2 clear lids you'd eliminate the bait panic associated with the sudden on/off of light when someone sits down. Also a buddy painted the inside of his a medium greenish-blue (like good sea water) and he says the baits don't freak as much as in a white tank. It won't take up any more space and will make it easier for 2 to fish without it being a nuisance. Just my 2 cents.
