I agree with Mary that the Wave is probably the best and simplest choice.

Only to give another alternative, maybe you could find a used Supercat 15 at a good price.

The SC 15 is very seaworthy (high volume floats) and easy to singlehand without the jib - if you are not lucky enough to find one with a self tacking jib.

Also, it performs significantly better then the Wave.

Cheers,
