22 to 24 for new couple
I, too, own a C-22. I bought her a couple of years ago with the intention of learning to sail before trying to move up to a cruising sailboat. This year, we had a blast with her, overnighting and weekending as often as possible. We have some friends who bought a Hunter 235 and we go out together sometimes. They have come to call our boat "The Battleship" because of her heaviness and stout construction.
Alas, we have now purchased our "step up" boat and our beloved "Patience" is resting under our house in the driveway.
