Largest trailerable sailboat
I don't know about the largest, but my C&C Mega 30 is a breeze launching off a trailer from a municiple boat ramp. At 8' beam and 2' draft for launching and the rig goes up in minutes. You can take this boat any where; and kick some serious ass on the race course. If your serious about sailing give this boat a trial run pure adrenaline rush. She is for sale if you are interested.
