I did a one week charter on an Island Packet 350 (down in Punta Gorda FLA).
It is a sweet boat. Down below there is a lot of room, and a wonderful layout.
It takes A LOT of wind to get it moving, and doesn't beat to windward well (but why beat to windward anyway).
I don't think I could ever get it in and out of a slip without a bow thruster
But as far as a seaworthy smooth riding sailboat, it's great.
I too am delighted with my perfect PS 31.
