Boom Brake Invention . . . from Italy !

After the invention of the bimini for my Belize 43 (see previous topic)) now i send you another idea to curb the boom. In the pictures you see a simple accessory that resists climbing up to 3000 kg. It costs only 10 € at the shops. In Italian is called: " discensore" look for it on Google and sail with it down wind in securety...
Hello from Gianniandrea

For sailors in the Caribbean: in 8 months I'll be there !!!!! i will go across the Atlantic with my Belize 43 from Tropea Italy to Martinique.

Ciao

No it's a brake. The friction slows a jibe. But I don't know if this "invention" has enough friction. It might if you really crank the line down hard. Most boom brakes have a worm screw or a few fixed grooves to increase the friction. This one looks a tad small.

Interesting. For gybes in big wind we crank the mainsheet amindships when the wind crosses astern and then let it out once the gybe happens. If that makes sense.

Brakes are to help slow an accidental gybe. Personally I use a restrainer and prevent them altogether.

Boom Brake Invention . . . from Italy

Not sure how much a figure eight (climbing belay device) would control my 20' boom .

These are boombrake's, which are adjustable in two ways. One by tension, the other by friction.




What you are showing is a repelling ring like what I use for rock/mast climbing.

The downfall to your set up is it will breakdown the line and eventually will fail to work once it becomes soft. You would have to replace the line quit often.
User beware.

Makes perfect sense... that's what I do in any wind. I hate to let the boom snap over even in light air.

Tried gyb-easy, which looks similar to this. Not impressed. Not to imply this product would work the same.

The gyb-easy seems to be either locked or free-flying. I found it hard to get it to be 'just right.

I have also used the dutchman boom brake. Dramatically better performance than the gyb easy. Much easier to adjust to get it to control the gybe, or even lock it in place if need be. Relying on sheaves intead of friction, seems to be a better system.

Got the gybe easy due to no moving parts, but after a season using it (about 600 miles), but could not get it to work as well or as smooth as the dutchman on our other boat.

I have a Walder boom brake, used it on my CS36 for years, worked well but a bit of a pain. Lines led aft, make sure it's well tensioned, etc. More lines on the deck to slip on. Now on my B393 I use a preventer to the midhip cleats, works fine. I still have the boom brake, it's in the bottom of my locker. Would be useful in trade wind sailing but for coastal cruising, too much work. Just visited their site and can't believe what they cost now. Next stop .. Ebay.
