Fantastic read you put together. Lots of good info that I'll come back to.

Engine trimming / balance point.... Wonderful. I'm amazed at this idea. Initial thoughts were to use weight up front and set the engine level. I'll definitly cut slots for adjustments on the rear and shim as needed.

Door hinges.... theres an idea. Simple and easy. To think, I've been racking my brain on how to come up with something on the mill. I'll look into the simplest way for this boat.

Rudders.... 14.5 x 2.5 Perfect.

Bottom area reinforcement..... Will do.

This is turning out to be one of the most enjoyable projects to date. No rush, but its coming along quickly.
