Can’t chose between four and five cabins? That’s no problem with Bavaria’s “flexschott” modular system that changes, in a few steps, the boat from a four-cabin model to a five-cabin model. The boat is also available in a three-cabin model with three heads. The 51 has roller-furling main and genoa, and the cockpit features a fold-down swim platform. LOA 51’1”; Beam 15’3”; Draft 6’1” Displ. 31,085 lbs.; Price $395,000; www.bavariayachts.com
