It is not a SwallowBoat, but that is my BayCruiser mizzen stuck through her fore deck. I have been building her over the summer and hope to launch her somewhere in the next few days. The plan is to tow her behind my BayCruiser 20 on some trips, and use the mizzen sail to sail her round the anchorages. I still need to sort out a rudder and soem sort of lee board arrangement . She is a variation of teh Portuguses Dingy by Hanu Vartial
