Hope that I do not come across as a junkyard dog pushing the i550 on you, but here are a few references of a boat the Gougeon Brothers built for the 2011 Everglades Challenge. Hot Canary is a modified i550 that needed to be launched from the beach, so they used a weighted keel foil without a bulb.This allowed it to be pulled up flush with the hull. In the last picture below, an i550 with the keel/ bulb retracted would be floating in knee deep water.

There are a number of plan holders/builders in the SE and a new #468 plan owner is north of you in Clearwater. As for the 8' door, we have had an builder that need to think like Gibs to get the boat out of the shop. There is a plywood cored boat that has been racing in Florida for three seasons. PM if you have any questions.
