I've got a copy of this and it's a fascinating read.
To summarise my Naval Architecture Degree:
1. More power and less weight = more speed.
2. Flatter bottom = more speed.
3. Deeper V = softer ride, but needs more power.
4. As you go faster the ideal location for the Longitudinal Centre of Gravity (LCG) is further aft.
5. Having an LCG aft makes it more difficult to get up on the plane.
6. Longer narrow boats normally give a better ride - but don't always perform well heavily loaded.
7. A wider boat will carry more weight more efficiently.
8. Tubes in the water at rest = more stable at rest, but probably more drag under way.
In summary for my needs:
