So where I live I can keep up to a 26X13 Cat on the beach. I currently have a Prindle 19, but often go out with 3-4 people which is a bit much for the boat in most Southern California winds. Ideas or comments on going bigger? I know about the Stilettos (slightly too wide), but what else?

Criteria:
Day sailor with good (similar to P-19) performance.
Beach launched (by 4 People)
26' MAX LOA
13' MAX Beam
