Capt. Don Stainless Steel 316L Boom Brakes

Sail any size boat with confidence. A boom brake is a great device for controlling an intentional gybe and a critical safety device for the unexpected gybe, particularly when sailing at night, short handed and in poor conditions. It reduces your work load, stress on your rig and worries.

Designed for 3/8 in to 1/2 inch diameter (9-12 mm) rope.

Install just like any other boom brake. An internet and Youtube search will provide many links and images. The choice and tension of the line (blue rope in images) changes the amount of friction created. It is common to dead end one end of the boom brake line to one side of the vessel and run the other end back to a cockpit winch via a block on the opposite side to adjust the tension. on multi-hulls I suggest that you rig it as far aft as possible. Why? Because you wan the friction brake to apply the total friction over as long a line length as possible. All the literature on the internet suggests 1/3 to 1/4 of the length of the boom back from the mast or to the boom Vang where it joins the boom. This advice is for mono hulls where the boom often extends beyond the side of the vessel, however the boom on a cat rarely goes out beyond the coach roof and almost never beyond the sides of the boat. A boom brake is a much better choice than a boom preventer as it applies a much lower force, however you can use this boom brake as a preventer simply by increasing the tension of the line (Blue in Image)

It is recommended not to fix to a single loading point on the boom. String a line from either end of the boom and attach your boom brake/preventer to that. That will keep all loads in compression of the boom.

If you cannot rig a line below the boom then rig one on both sides of the boom and attach the brake to both either directly or from a line to them.
