The recent discussion regarding spherical mock-up construction has me taking another look at something I had in mind.
To form the curved surfaces of my ambient marine ply design, I have in mind epoxy laminating thin layers of ply over longitudinal supports notched into traditional transverse frames. I need those frames to baffle a whole lot of free flooding spaces and soft tank spaces anyway, so they have to form the hull exterior. (The crew compartment is modular and hidden from view and structured to contain the lead ballast).
As I apply this to my 3d model, I see a lot of material taking up a a lot of displacement volume and therefore requiring additional compensation ballast.
Suggestions on how to cut down on the framework volume and still maintain fair curves with rigidity would be greatly appreciated.
A second question is regarding mechanisms for release of a heavy lead keel. If someone could point me to examples to look at?
