Boom_brake

Boom brake with line. The brake shackles to the bottom of the boom, and the line attaches to the base of the shrouds; tensioning the line actuates the brake.

A boom brake is a device designed to control the swing of the boom on a sailboat. The boom brake acts as a preventer when sailing downwind, and can also be used to jibe the mainsail in a slow measured action.

The brake usually rides on a line running perpendicular to the boom; when the boom brake is actuated, it grabs the line and either works as a preventer, or slows the boom’s speed while jibbing. The brake is actuated by either tensioning the line upon which it rides or using a second line to tension the brake relative to the main line.
