Better Boat: The Virtues of Heft
Our Bertram 64 test boat, the fourth 64 that Bertram’s launched, was hand-laid in Bertram’s old facility in Miami and trucked to the new facility in Merritt Island, Florida where her various components were assembled and finished. Typically, hand-laid fiberglass is heavier than glass produced via resin-infusion, a technique Bertram will employ on subsequent versions of the 64. Geney Menendez, Bertram’s service manager, says our hand-laid 64 tipped the scales at 102,000 pounds when weighed, a hefty figure, at least by comparison with nummerous other 60-plus-footers, some being battlewagons. Of course, extra weight often boosts seakeeping and comfort but reduces speed and the folks at Bertram, although happy with our our test boat’s 36.8-knot top hop, are shooting for 38 knots once they cut displacement (by approximately 10,000 pounds, according to Bertram’s designer Robert Ullberg). “But even then,” says Bertram’s vice president of sales Don Jones, “I think you’ll find that our boat weighs just a little more than anybody else’s. And when you combine that extra heft—that extra weight—with our extra-sharp, wave-splitting forefoot, that’s where you get the softness and the dryness of the Bertram ride.”
