The past weekend I had the opportunity to crew for the owner of the Powercat 'SiverVoyager' that was designed by Graham Byrnes and built by B&B Yacht Designs. I have personally spent about 4 years full time on the built team. She was put up on the hard to have the props re-pitched and as well as add a wedge and side fences to the transoms. The reduced pitch increased the full throttle engine RPM at the manufacturer's request. The fences and wedge were added to trim the bow down slightly. Initial sea trials showed about 2.5 degrees of bow up at cruise in flat water which was reduced to 1.5 degrees. At 15 knots it's like a magic carpet. Just an incredible feeling of speed. Videos below.
Below, shot at the mouth of the Neuse River. Boat speed is 9.5 knots. Head sea just off the port bow.
As we made our way south the fetch was reduced and we were able to resume 15 knots cruise speed. Please forgive the brevity of the video, I was standing up to a 30 knot apparent headwind.
Finally this is the wake at 15.5 knots. The fences and wedge improved the flatness of the wake. Overall very little wake considering the speed.
