Boom Brake Owner’s Manual Introduction The Dutchman Boom Brake is simple, reliable device to regulate the boom speed. How well the Brake will work depends on proper installation. You also will have set the tension correctly for different wind speeds. Please follow these instructions carefully. -
Page 4: Specifications
Specifications 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. -
Page 5: Installing The Boom Brake
Installing the Boom Brake How well the Brake works is determined by the installation. Read these Deck Attachment Points instructions carefully. First, identify the best possible locations for the deck attachment point, then the boom attachment point. Do not install any hard- Chainplate ware until you are certain of BOTH the boom and deck attachment points. -
Page 6: Check Line Tension
Check Line Tension Set the boom height to the lowest normal sailing position and snug up the vang. Locate the boom on the centerline. Temporarily run a line through a block or a shackle temporarily secured to the boom attachment point. Tie or tape the block or shackle to the boom if needed. - Page 7 If the line can not pass through the toggle, install an eye splice with a thimble in the end of the line. Follow the directions below to complete the installation. To attach hardware like a block or a shackle directly to the chainplates, use lacing line, which is more reliable than a poorly aligned shackle.

Rigging the Brake Brake Line Fixed If you want to be able to run the adjust- ing line back to the cockpit from the base of the mast, you have 2 options. Either use a block and tackle to pull the bail aft to tension the brake, or use a single line run to a line stopper and a winch. -
Page 10: Operation
Operation Using the Boom Brake is simple enough. Just adjust the tension on the Brake line to regulate the speed of the boom. Practice to get a feel of how this works. In light winds, you may want to let off on the adjusting knob to reduce friction. In winds over about 10 knots, the knob must be tightened. -
