The Princess Sharpie is a predecessor to the Core Sound line. But there are similarities in the designs, I believe. I have never owned one, but have a friend who did. I’ll nudge him to share his thoughts. I do own a Bay River Skiff 15, however, and can comment on the rig. This boat was my first experience with a cat ketch, leg-o-mutton rig, and I love it. It is a more efficient sail shape, I believe. Making a gybe manuver is effortless and worry-free. Heaving-to is simple— I do it all the time when sailing solo, and need to tend to something away from the tiller. And my wife loves not having to duck for a boom or tend to trimming the jib. (The sails are self-tending, with controls leading to the skipper.) Yes, I love this rig.
