Capt. Don Stainless Steel 316L  Boom Brakes. Sail any size boat with confidence.

A boom brake is a great device for controlling the boom swing during an intentional gybe or even going about and a critical safety device for the unexpected gybe, particularly when sailing downwind, at night or short handed, and essential in poor conditions. It reduces your work load, stress on your rig and worries. See the video of use on a Bristol 32:  http://youtu.be/yCkFUGl12xw

Complete parts list and larger images of the above Bristol 32 installation.

When at anchor a boom brake can be your best friend as you will no longer have to hear your boom swinging side to side even when there is no wind and a swell rolls your vessel. It is an inexpensive safety device that should be on every sailing boat.

I have always dreamed of sailing the world and started the journey to fulfill my dream by going to sea full time for over 3 years on commercial vessels and getting certified as a M5 Captain and engineer. Friends asked me to make a boom brake that did not ruin a cruiser's budget. Well, after about a year of testing various hand made samples I am happy to say that I can now offer a 1/2 inch thick Stainless Steel 316L boom brake that is stronger, better value and just as efficient as any other boom brakes now available.

Your support goes directly to helping my wife and I get a boat and hopefully fulfill our dream of sailing and kick starting our non profit: http://dreamgreen.org/

The Capt. Don Boom Brake has a yield strength calculated to be 9800 pounds before elongation so you can use them for other applications. Remember that the mast and boom absorb most of the sail loading so this boom brake can be used on a sail with a loading far in excess of the yield strength of the boom brake.

The brake can be attached directly to the end of the Vang at the boom or to a bail in the boom track just behind the Vang or to a line wrapped around the boom but the best is to rig the way that serious racers attach boom preventers, by running a line under the boom or on the side of the boom between both ends and attaching the boom brake to that. This eliminates any boom point loading and keeps the boom under compression. See images of a Catalina 27 rigged this way.

It is often easier to attach the friction line to the top of the shroud turn buckles. see images. This provides the clearance to prevent the friction line rubbing on the coach roof which can cause changes in line length thus changes in tension and friction. One side can be run back to a cockpit winch for tensioning or a set of blocks with cleat can be attached between the shroud turn buckle and boom brake at the lower end of the friction line, see image to provide tension adjustment without cluttering the deck. Once set it should require little adjustment for changes in wind strength.

A boom brake is a much better choice than a boom preventer as it applies a much lower force and unlikely to break your boom like a preventer if not rigged properly.  Remember that a boom brake can be used in conjunction with a preventer since a preventer has to be released to swing the boom and thus the brake will take over until the preventer is again set on the opposite side.

I put together a short video of our boom brake used on a Catalina 27 and of course included some dolphins. http://youtu.be/GGWI9OqsDFk

Remember:
1/ You do not need to use the winch to tighten the friction line, hand tighten is often enough.

2/ A change of only an inch in the friction line tension makes a big difference. As the boom swings the friction line length will change and thus the location of the boom brake is important to minimize this change. If in doubt about position please do not hesitate to contact me and I can do some calculations in a spreadsheet to show what impact your vang, shroud, boom arc and boom brake locations will have.

3/ If you find that you have a nice moving boom swing in one direction but not the other then try tying both ends off at the top of the shroud base turn buckles. It seems some folk have a line with too much stretch and when the one side leads back to the cockpit more stretch occurs on this side causing this problem. This problem has also occurred when the boom brake was placed too far aft on the boom, typically attaching about one third aft the length of the boom is good.

4/  If the brake jams, you might have too many friction line loops in the brake, change to match the images above, the geometry needs to be adjusted or your friction line is too thick. Start with a friction line that is approximately 3/8" diameter or even less on small boats that are in the low 20 ft range or smaller. It is always best to begin with a low friction setup and if it works but is loose try a slight change in tension before changing to a thicker line.You are welcome to contact me and I will do some CAD calculations to suggest the optimum boom brake attach points.

Hope this helps.

Capt. Don

Comments:
Joe Anshien 2014-05-01 : Used the boom break on delivery from Martinique to Annapolis. Worked well.

Rodney Wood 2014-8-20 : I have an old IOR 1 ton warhorse with a fractional rig (rather long boom).   
The Boom Brake worked great during the Summer Social buoy races with novice/passengers on board on the down wind legs.

Peter Puky : Don, suspending your brake from the boom ends turns the entire boom into a "compression post"! This makes the boom bullet proof! A very strong method of diverting the energy. As a rigger (historic = 25 years ago) I love it!! I purchased 3, one for me and the others for members of the WORLD CRUISING CLUB team.

Steve Kratchman: I only went out the day before pulling for winter but come spring I will experiment with my line sizes, however, I do have a 3/8 line now and that did work well enough. The mainsheet went over quickly but did not bang against the stops as it would have normally. So I am very pleased with my setup although now I have it tied off at the strbrd inboard shroud turnbuckle and am using the cam cleat block at the port inboard turnbuckle. It does make it quicker for testing tensions. 

I am going to place pics on my Pearson list but am listed on a cruisers list as well. I might suggest you make contact with Practical Sailor and Sail zines as they both have pages for   Interesting and new items, especially at reasonable prices. 
I will keep you informed.
'87 39-2 Pearson, SOLOMONS MARINA, MD

Ed Martin: After some initial difficulty and testing I followed Don's calculations and rigged the boom brake 48 inches aft of the Gooseneck on my Bristol 32 and it works great with the same friction when the boom swings  both sides, slowing it down nicely to a comfortable speed where no one is going to get hurt but not too tight so avoiding any excess load on the boom.
