These specifications are for conventional, moderate displacement monohulls, and are provided as a rough indication
of which Boom Brake and installation kit should be used. Heavy displacement sailboats or sailboats which will be
undertaking extensive offshore passages must use oversized equipment. Use the next size larger installation kit to start
off. Contact us for more information.

The BB250, BB500 and BB750 are used with rigid vangs, where they are fitted just behind the rigid vang, or in a
soft vang application with 2 attachment points (bails) on the boom. They would also be used if you don't have a vang.
The BB250B, BB500B and BB750B have an additional shackle secured to the bottom of the brake. They are used
on boats with 'soft' (block and tackle) vangs. The brake is attached to the vang bail on the boom, while the vang is
shackled to the bottom of the brake.

These specifications give the minimum SWL's (safe working loads) for the mounting hardware and the line diameter
and length to run the line back to the cockpit. Any parts you supply or use should follow these SWL recommendations.
These specifications are provided as a starting point. You may need to go up one size, depending on what kind of use
you are planning, and if the attachment points are farther inboard than normal.
