In Response To: How does prismatic coefficient affect design? (Jeremy McConnell)

Prismatic coefficient gives you an indication of the "fullness" of a hull shape. As you have probably heard already "hull speed" is dependant on length. But a boat with very fine ends will have an "effective" waterline length which is shorter than the actual waterline length. This will be a boat with a low Cp.
