Installing the Boom Brake

How well the Brake works is determined by the installation. Read these

instructions carefully. First, identify the best possible locations for the deck

attachment point, then the boom attachment point. Do not install any hard-

ware until you are certain of BOTH the boom and deck attachment points.

Use the following criteria to select the ideal location for the

deck attachment points.

1. As far outboards from the mast as possible.

2. Within one foot / 30 cm fore or aft of the farthest aft (shroud) chainplate

(closer is better).

3. Clear of walkways if possible.

The most common locations, in order of preference, are:

A. The aft lower chainplates if they are set inboards. We will discuss an

easy way to attach items to the chainplates later on. Normally the best

location.

B. A car on an inboard genoa track if it extends to the chainplates.

C. A pad eye through bolted to the deck.

D. A pad eye at the corner of the cabinhouse, if a high cabinhouse with

narrow decks like on Valiants, Pacific Seacrafts, or Island Packets.

E. An attachment point on the toerail, or midships cleat.

A Brake line secured to the toerail will cause a hazard when walking forward. Some owners add a shackle so that the

ends can easily be disconnected when the Brake is not needed, although the Brake is handy in many situations. To

prevent damage to an aluminum toerail from a shackle, consider Winchard's" special toerail shackle. Higher alumi-

num toerails will deform if too much side force is applied. We noticeably bent a 2" high toerail on a 38' boat with a

400 square foot main in about 20 knots of wind. (We now have our own test boats!)

Most boats have several possible attachment points. Try to locate several possibilities, then move on to

locating the boom attachment point. Again, don't install anything yet. We'll

deal with that later.

Next, determine where the Brake will be attached to the boom.

The brake will be about 1/4 to 1/3 the boom length back

from the mast. More precisely, the brake will be about the

same distance from the mast as the deck attachment point is

from the mast. Use the existing boom vang attachment point

or bail as a starting point. If the boat is fitted with a rigid

vang, the Brake should be aft of the vang.
