There are, however, many good reasons for choosing a V bottom hull over a flat one. Someone experienced in observing these wave patterns might infer the angle of deadrise just from looking at the waves generated by the boat. (bluejacketboats.com)

A higher deadrise angle will give better performance in rough waters, but a lower deadrise angle is more hydrodynamically efficient and thus can generate better acceleration and a faster top speed. (Jelsoft Enterprises Ltd.)

This transducer’s unique design allows it to be mounted close to the vessel’s centerline without drilling holes, and is able to correct for the hull’s deadrise angle. (Airmar Technology Corporation)
