Anti-Capsize Systems.

[Nicocrispi]

It's been quite some time since an old thread on this subject (sorry if I missed a more recent one) and I'm asking if anybody here has installed one of the available anti-capsize systems and can report on their experience.

Etc.

SailWilding blog discusses this recently. They had it installed.

I'm curious about these as well, & the topic in general. And while it's not 100% in line with things, I've noted that there are a LOT of folks out there who don't realize & acknowledge the dangers of running the sheets on multihulls through line clutches.

Check out the Sail Wilding blog. They put one on their Outremer 5x. Not a ton of info there, but you can see pics of the installation and some commentary.

The BEST Anti-Capsize System is already built into every catamaran on the market.

Its called a REEFING system.

Works GREAT.

Its SIMPLE

Its CHEAP

It already comes with every boat.

The next step, after all the 3 REEF's are in is to stow all sails and start your engines.

OR you can Spend $40,000 and have a COMPLEX unproven Anti-Capsize Systems do it for you.

I wonder if they apply to cruising yachts in the same way. Racing boats capsize because they are pushing to edge and occasionally beyond. An attentive crew could easily make small sheet adjustments, but this is not possible for singlehanders, so an auto-release is a logical pairing for auto-helm.

Cruising boats capsize because they are caught by a sudden hurricane-force gust, often from well aft, which often cannot be controlled by slight easing of the sails. The proper solution is usually aggressive reefing, which this machine will not do. If cruiser is sailing to weather in strongish conditions, and must leave the helm, he can simply drop the traveler a little and achieve the same thing. He isn't racing.

Finally, unlike a human, it cannot have the ability to predict whether this is a limited gust, or a severe downdraft associated with a thunderstorm. A human should have been looking at the clouds and anticipating.

I'm not saying it isn't interesting, if you have the money. I'm saying it may not do what cruisers think it does.

True, unless of course that human is catching a wink.
Otherwise I agree with most of what you say in your post thinwater.

Exactly. If I were singlehanding a race, it would at least be a help. I'd have some alarm features as well (which I'm sure they do) for changes in windspeed and gusts, and of course, if the devise triggers.

But I would also know that it could only function properly with the wind well forward of the beam.

[svrecess]

Why is that? If it's load based (and probably also taking wind angles into account for determining max load), a strong gust from behind or from any angle would still be something it could sense would it not? You just set the loads and angles accordingly I would think. I have not looked into it yet though.

Those would be really nerve wracking to test, and I'm a big fan of testing systems before relying on them.

The Rapier 550 has this system as a standard feature. See Toby's review on youtube.

[CbroTheDude]

The system used on the Wildling 5X is the UpsideUp, as the Rapier 550 and many of the big multihulls, either racing or luxury cruising. Demo of the system in actionhttps://youtu.be/1P0vINB_kLQ

you are not racing, so reef early, avoid stress

It seems like an application where a mechanical system would work better.

A dampened pendulum for boat angle and a simple tension release. Easy adjustment, easy to see working.

If the figure above of $40,000 is accurate a mechanical one would be around 10% of the price.

I did try this Hugo Myers pendulum sheet release system long ago on my Moore 24 for my solo sail in the Newport to Cabo race. It works only on one axis and can bind on an angle. Simply not good.

Later I rigged an angled swivel cam cleat with a bungee cord to keep tension on the swivel of the cam cleat and adjusted the turns on the winch and the tension on the bungee to suit the point of release. This works really well as long as the winch has a smooth drum -definitely not knurled- and the line is not wet.
