N.B.  Boom Brakes take the stresses and strains out of gybing.

Gybing can be a tetchy and potentially hazardous manoeuvre for even the most experienced sailor.
Down-wind sailing should be pleasurable, but the enjoyment can be marred by the necessity to remain constantly vigilant for the possibility of an accidental (Chinese) gybe.

The consequences of a boom crashing from one extreme to the other could be fatal, but the mishap could almost certainly result in some sort of gear damage. 

Walder® eliminates the crash from a crash gybe

The Walder® boom brake controls the horizontal and vertical movement of your boom – it replaces the kicker rope tackle for most rigging plans (not a rigid vang) – it doesn’t stop the boom abruptly, but controls the speed of the boom crossing the boat.
Walder® Boom Brakes achieves the dampening effect using the frictional force produced as the line slides and tightens around the drum.

Once the Walder® boom brake is rigged and the control line is led aft, the required tension can be applied without leaving the safety of your cockpit.

Walder have developed the original 1976 design into an evolutionary range of models to fit sailing yachts with mainsails up to 1180 Square feet (approximately 100 metres²).
