A friend brought his Catalina 42 down the west coast in heavy weather, using
a nylon preventer.

As it turned out, there was enough pressure on the boom at one point to
stretch out the nylon preventer as the boom went midships, then snapped back
forcefully and pulled up the traveler and forced him to put in for weeks of
repairs.

I expect that the "shockle" would have the same problem deployed as a
preventer. It's a great idea for lots of other places on a boat, but not as
a preventer (IMHO)

A friend was telling me about a product review in 48 Degrees North magazine
about a device to prevent accidental jibes. Something called shockles. Found
their website, www.shockles.com. Anybody have any experience with these?
Look like they might work? Thanks.
