$11K + a lot of man hours and no sailing, yuk!!! There is a relatively new Viper in OC, MD listed on CatSailor. Complete rig w/trailer and beach wheels, and not much more than your $11K. Also, a very new Falcon in SW Florida on CatSailor. Probably can get a good deal also.

There is nothing like building your own boat but it is a lot of blood, sweat, and tears.

Maybe build hulls at your leasure while racing a Viper or Falcon. You could use the same rig.

Good Luck.
