Thanks for the advice / guidance guys.

Deck hatches are out. Yeah, the tank is about 27-7/8" wide.

Even if I cut part of the flanges off both sides, I'm still gonna have a heck of a time cutting out the foam down in the crevice between the stringers and the sides of the tank. The deck proper and fish boxes (part of the deck mold)lap over past the stringers both sides, and I sure don't want to cut out any of the deck or the boxes. Maybe with a flexible blade "keyhole" saw I'll be able to bend the blade around the deck edge and back down into the crevice and cut out the foam. If not, I'll be into a really tough job of cutting up the tank in place and removing it in pieces.
