The mandrel lock is located in the outboard end of the boom, close to the leech of the sail. This location minimizes mandrel twist when sailing with a reef, ensuring a flat sail when it's needed most. The aft compartment protects the motor and lock, giving the boom its clean look while allowing easy access to the motor for routine maintenance.
Our newly redesigned inboard end attachment incorporates a double lug and Hall's signature gooseneck design. This configuration transmits the vertical load from the hydraulic vang into the mast, improving the strength and reliability of the overall system.
The clever tapered design of the carbon-fiber ramp feeds the sail smoothly from the mast onto the mandrel, allowing a tight furl of the mainsail even with full battens. This results in a boom shell that presents the sleekest profile possible. Constructed of autoclave-cured carbon fiber, the mast ramp is weight optimized, strong, and presents a low windage profile.
The bolt rope, feeder and gooseneck pivot around a common axis, reducing bolt rope friction and sail distortion when reefed or reaching. The reduced friction results in reduced wear on the bolt rope and batten ends, prolonging the life of the sail.
The Oceanfurl can be reefed or furled when sailing downwind. With its pivot point below the main luff, its furling angle is wider and more forgiving than other systems.
