Which shape is better for lw hull?
Many people think a hull is faster without rocker, as on trimaran hulls. Many racing trimarans have rocker on main hull and straght side hulls.
But... straight hull does not give much hydrodynamic lift when the nose is pressed as well designed rocker hull does , or does it??
On a proa to have some hydrodynamic lift on forward of the mast would be an advantage, or would it? any comments.
I am not 100% convinced about having main hull without rocker.

Arttu
