37' BERTRAM 37 CONVERTIBLE SPORTFISHER (1990) OFF MARKET
This boat represents Bertram's entrance into the world of modern, lightweight construction- but it debuted on Bertram's terms, stressing above all else structural integrity. So while the 37 is lighter than your average Bertram, it is still classically overbuilt. You'll find extensive use of Baltek balsa coring here, a material the company feels is superior to foam coring in the marine environment. The hull is cored above the chine from bow to stern across the transom. Below the chine is Bertram's classic hand-laid single-skin construction, yet here as virtually everywhere else, at least a taste of tech intrudes. Conventional woven roving is replaced by layers of 0/90 bi-directional knitted fabric. The result, says Bertram, is a lighter, stiffer laminate. More Baltek is employed in the deck, for ward windshield (now solid and an integral part of the deck), cockpit, hardtop, and bridge, again with the aim of saving weight while maintaining strength.
