Replacing a popular boat, like the 55C, is always a challenge. The 56 Convertible succeeds handily in a number of ways. Longer and wider than its predecessor, the 56 Convertible shares the sleek sheer line of its newer stable mates. Upon closer examination, however, the differences, both major and subtle become apparent. Nearly a foot wider and with considerably more flare than the 55, the new 56 features significantly more crown on the flying bridge deck. Aft, the cabin sides taper inward slightly, a design tweak that helps to eliminate the station wagon effect when the boat is under way.
