The F16's have daggerboards. There might be a F16 Gcat still hanging around down here in Florida somewhere, no boards, someone may chime in here if it's still available. The Nacra 450 or 500 is a good boat if you can find one in good shape and ready to go. No boards.

Boards are not that big a problem and can help you tack on a dime, just remember to pull them up before you run it aground.
