If you have not bought a new powerboat in the last few years you may have missed a quiet revolution in design that has taken place. Subtle changes in hull design have produced performance benefits which were not possible previously. The newer boats plane a little more efficiently but the biggest change is in the cornering.
Flat turns are very prominent in the new generation of vessels afloat.
I first notice this change in a 21 foot production boat built by Hinterhoeller. It's performance was quite startling at the time it was first launched, and this vessel became quite popular in Eastern Canada. Today all the newest boats have picked up on this design revolution. These new boats have been developed through extensive model testing, research, and development. It has been found that by adding a wide chine flat there is an increased in the stability of the hull both at rest and underway.
