Mike,
Precisely! I figure boats "vary" their displacement by "sinking"! Sinking is easy, sinking with some control a bit harder, coming back up again harder still, staying alive....priceless!
I will look at the designs you mentioned for ideas....Thanks!
Joe

Beautiful project, isn't it?

I've had the same sort of idea in mind for several years. I call it
a diving boat: it's always positively buoyant, and it dips underwater
using the planes only. There might be some ballast taken in to
reduce the freeboard, but in general it's a surface ship. Done
right, and kept to a minimum depth, it might not need any
electric motors.
My choice of hull was a Laurenti design from 1912. It became
the G-4, and was an unstable piece of trash, but the shape is what
attracted me. It's long and low, and has a small conning tower.
My second choice of hull was taken from the German Type IX.
That has a wide flat deck, just right for deck chairs in a 1/10th
replica.
