The mast is so far forward on the Hunter 33 that I don't know where and how to install a preventor. Even when the boom is as far out as it will go, the angle between a line going from the boom end to the prow and the boom itself, is too small (IMHO) to make the preventor effective.

Also, when sailing in very light wind, the wind force on the sail is sometimes not enough to overcome gravity on the boom, so the boom crashes back and forth as the boat rocks in the waves. A preventor would be great to stop this too.

Looking at the configuration of my boat, I'm often tempted to lash the boom to the shroud. That would overcome these problems, but is probably not a good practice (shroud may not be strong enough in a true accidental gybe).

How do you other folks cope with this?

On a related problem, whenever the boom does swing out and comes to a rapid stop as the mainsheet gets tight, it makes an unholy and very disturbing banging noise (especially disturbing to my wife). I think this is because of the lines inside the boom slapping against the aluminum of the boom. Anybody else bugged by this? Any suggestions to cure?

You can install a preventer line from the end of the boom back to the rail close to the mast through a block then back to the cockpit to a winch,cam cleat or cleat. You can also install a boom brake such as Scott Boomlock, Wichard Gyb'Easy, Dutchman, Walder and Fleming. I use a Walder. The boom brake offers the advantage of slow and controlled jibes.

I was very interested in Dave's contribution. No, I was not aware of these boom brakes. Does anybody with my model of boat (Hunter 33 2007) have any practical experience of how well it will work on this configuration?

I have had a boom brake on my H33 for 4 years and it is a godsend for cruising down wind, you can happily read a book without fear of an accidental gybe. Additionally in light winds and choppy seas it will steady the boom and prevent banging and chafing.
When I first got it I tested it out in 25 knot winds flinging the wheel over to do a deliberate gybe and with a fair bit of trension on the brake line the boom just gently cruised across.

What brand/type of brake do you have? Can you take some pics and share?

got one!

I started this thread a few days ago and was so inspired by the positive comments that I got a boom brake - a used one at Minneys (Southern California folks will know that store) for $29. I don't know the brand, but it is a drum with fairleads for the tension line coming in and going out.

To install it on my H33 (2007) my plan is to attach it to the metal loop at the connection point for the boomvang and boom. Then attach the tension lines to the chainplates - one side with a shackle, and the other with a turning block to bring the line back to the cockpit. I don't know how this last bit should attach - it would be great to use the jib winch to apply tension, but, of course that winch is in use at that time for the jib! How have others done this?

Seems to me that the tensioning line should be nylon so it can stretch and keep even tension. What do you think of this?

comments welcome
