The Bertram 31 is the first production deep-V, drawn by C. Raymond Hunt and built by Dick Bertram's Miami yard from 1961 into the early 1980s: a light, sharp-vee twin-inboard sportfisher that runs through a chop where flatter hulls pound. It suits the buyer who wants the rough-water seakeeping that made its name and accepts the trade that comes with it, a wet ride, a heavy fuel bill, and a hull that rolls at rest. This reference is honest about where these boats age, from the balsa-cored decks and hull sides to the boxed-in belly fuel tank you cannot inspect, wet stringers, and the six-figure diesel repower that separates a cheap project from a finished boat.
