furling booms Raise your mainsail, reef your mainsail, or furl your mainsail with the touch of a button. Enjoy the superior performance of a fully roached leach and the shape-optimizing benefits of full battens. And sail with greater assurance and safety using a sys- tem that does the job whether you're headed upwind or down. That's PowerFurl, GMT's in-boom roller furling system. With its beautifully shaped and finished carbon fiber boom, this is not only the best looking system on the market but also the most functional. PowerFurl eliminates the problems which pre- viously kept yachtsmen from choosing in-boom furling. GMT's PowerFurl in-boom roller furling system combines careful engineering re- finement, significant weight reduction, and handsome aesthetics. Each of GMT's PowerFurl booms Is custom built to suit yachts from 45 to 90 feet, and structural engineering has been completed for even larger yachts. John G. Alden Design drew the very sleek and pleasing profile, whose section-size dis- guises the fact that entire mainsails can be fully enclosed.

furling booms GMT's furling motor is easily accessible in- side the boom's forward end. Many furling booms place their heavy motor at the aft end, requiring longer, heavier hydraulic lines and causing the boom to swing more violently in a seaway. Experienced sailors also favor in-boom furling to allow full-length battens for optimum sail shape and efficiency A streamlined and removable end-piece pro- vides easy access to the electrically actuated ratchet. The ratchet locks the aft end of the mandrel. Deck and cockpit lighting can easily be included within the PowerFurl boom In addition to...
