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.

With the block and tackle method, attach a block

and tackle to the bail (or the brake shackle that is

also run through the bail. The other end of the block

and tackle would be secured to an attachment point

aft of the brake bail. The line would run from the block

and tackle forward to the gooseneck, then down to the

base of the mast, and aft to the cockpit to a line stopper or

cleat.

With the winch method, run a single line from the bail, aft a foot or

so around a block and back forward to the gooseneck, down to the

base of the mast and back to the cockpit. The line will be tensioned

Using a single line to pull bail back

with a line stopper and a winch.

Before you head off sailing, you'll want to test your installation.

1. First, with the adjusting knob loosened by 2-3 turns, snug up the brake and

push it through it's arc. Make sure the line can not catch anything, and that the

tension does not significantly change as the boom swings all the way through

it's arc from side to side. See the section Checking the Line Tension for

more information.

2. Next, tighten the adjusting knob and brake line as tight as possible, with

the boom swung all the way out. Have someone pull in the mainsheet, while

you check that there is no movement of any of the hardware that shows a sign of weakness. Look for chainplates

bending, or the fiberglass around the pad eye moving. Use a straightedge to check for deflection.

3. Finally, swing the boom out again, tighten everything as much as possible, and pull in on the mainsheet. It should

require as much force as it takes to pull the boom in on the windiest day of sailing you are likely to encounter. If the

boom can easily be pulled in, you are either not tightening the brake line enough (you need a higher ratio block and

tackle), or the line diameter / brake is too small. Contact us for assistance.
