There are a lot of things to consider in hull design. Dead rise is a big factor, weight, and hull structure.
For example a Sea Sport 24' gets 2 miles per gal an hr better than a 24' Orca, that is due to the hull design but the Orca can handle bigger water.
In regards to interior comfort, boats that have foam injected hulls are heaver and a lot quieter and warmer than none injected hulls, but to injecting hulls is big $$$ so that is why Orca, Grady's and other boats with injected hulls cost so much. There is also the type of stringers used (wood, fiberglass, carbon fiber) that could add additional costs and strength to the hull when hitting those big waves at 30 mph.
