Eliminate Accidental Jibes!
Even in moderate winds on smaller boats, the force of the boom when jibing can be deadly, let alone potentially damaging to the rig.
Although inexperienced crew or guests are especially at risk, knowledgeable sailors have also been killed or injured in jibing accidents.
If you want to sail downwind without worrying or having to set up a preventer, the Dutchman Boom Brake is for you.
The Boom Brake uses the same principle as a line wrapped around a winch to control side-to-side boom movements.
Under tension, the boom brake works like a preventer. Ease the tension, and the boom swings at a slow, controlled rate.
With the tension off, there is no effect on the boom's movement, and tacking upwind is not affected.
No more near misses or worse, because the boom never has a chance to speed up to dangerous velocities.
The boom brake uses a line (not included) run from the chainplates to the brake.
You regulate the boom speed by adjusting the tension on the line.
Models BB 250, BB 500 and BB 750 are used in these applications:
- Rigid vangs
- Soft vangs with 2 attachment points (bails) on the boom
- No vang
Models BB 250B, BB 500B and BB 750B have an additional shackle at the bottom of the Brake. The Brake is attached to the vang bail on the boom.
The vang is shackled to the bottom of the brake.
- Used with "soft" (block and tackle) vangs
Typical Boat Size
Max Mainsail Area
Safe Working Load
These specifications are for conventional, moderate displacement monohulls, and they provide a rough indication of which Boom Brake to use.
Heavy displacement or offshore-intended sailboats should move up to the next larger Brake if near the maximum sail area.
The Safe Working Loads are for the respective Brake and any mounting hardware used to secure the Brake or to run the line aft to the cockpit.
Any parts you use should follow these SWL recommendations.
