I sort of know where deadrise is measured from but what does it mean on performance and handling!! is higher the figure the better sea boat????

Depends on where you measure it from. Theres a lot more to a hulls capabilities than just the dead rise. Shape,flare and rake of the forward sections etc etc , and of course the skipper or helm. Put joe average in an F1 car and he'll probably crash it.
Deeper V's can normally travel faster in choppy conditions though without slamming.

Re: Depends
Agree with everything Barry says.
Consider a deep vee and a much flatter bottom boat, the deeper the vee the less the uplift so more power is needed for the same speed but it will cut through the waves rather than bang on them. So true offshore racing boats have deep vees to keep going faster (and not smashing the crew) in the rougher stuff but for the same power will be slower than a flattish lake-style boat.
However, there is a lot more to it like strakes and chines for spray control and lift, stepped hull to break hydrodynamic drag. As Barry says the shape of the hull rather than the raw angles seriously affects the boats handling, wave tolerance as well as speed - Long live Olesinski !
