Automatic sheet release system ?

    I have just bought a Corsair F28, that I will be sailing solo and going offshore like my last longer passage (see below), but am wondering about a system using a angle sensing omni directional switch that triggers 2/3 solenoids to release main,jib, asymmetric sheets. Any ideas/ thoughts ?

    Your post is a bit confusing.

    Are you referring to the video at 12 minutes or something else?

    No the video is just to show the stuff I do. I am just slightly concerned about solo on a 28 ft trimaran, and a autopilot failing or motor stalling, and then thought about an auto sheet release that would be able to release the sheets to help stop a capsize.

    Maybe Richard Woods might offer some ideas.

    Search here or on Woodenboat.
    There was an extensive thread on this same subject.
    There were 4 or 5 reported systems, one on one of the big 60 or 70' racers.

    My opinion as always is worth what you paid for it.

    My first question is why are you carry that much sail on a trimaran ? They are easily driven, fly minimum sail. You are cruising, anything over 8 knots is going to crush you over time. It would take a monumental escalation in wind strength to go from 8 knots to capsize. Multi almost never go over sideways, they pitchpole. A properly sailed multi should never get anywhere near capsize, that's for racers. Even capsizes in hurricanes/cyclones are fairly rare unless the crew have done something very wrong. If it's rough or blowing a gale down all sail deploy a sea anchor and wait it out. At that point you have a massively stable raft, albeit a light weight one. Hard to kill.

    Having said that you can buy clam cleats that let go under load. You could probably rig the main sheet to not cam cleat and you can adjust teh clam cleat to a tension you think is reasonable. You could probably rig the tail to a bell or something to wake you. I assume you are doing this to sleep on an ocean passage ?

    Probably worth reading the RW account of his encounter with 70' waves in the atlantic on eclipse.

    Personally I would think a 28' corsair is not an ocean crossing boat. I don't know if Ian Farrier's website is still all up but he documents corsair problems and if I recall correctly the F28 had issues, possibly with the pivot pins ?...memory isn't what it could be.

    I think a 28' trimaran is suited for a 2nd set of hands.
    It would be best to make sure Farrier is onboard with that boat being used as a bluewater boat.

    He may have some stuff for you to modify/check on the boat.

    Fallguy - Farrier is dead.

    Why is everyone being so negative.
    Lots of 28' boat have gone bluewater.
    Some singlehanded.
    If that is what he wants to do why not help him, instead of being armchair naysayers.
    Anyone can say no, it takes some intelligence and courage to make something work.

    Oh, silly me. I forgot. It was about a year and a half ago already.

    The reason this happened is I was reading some stuff on a blog he had written just a couple weeks ago.

    Because I don't want to help someone kill themselves ?

    The CORSAIR 28 was built after IF and Corsair parted ways. IF used to have a page I can't find now detailing the problems with various corsair models. I'd go to sea in an F82, I'd want to go over a F28 with a microscope before I'd sail one.

    http://www.f-boat.com/pages/backgro...w.f-boat.com/pages/background/separation.html

    This page is still up, I can't find the other one.

    But I am also concerned about the approach of adding an automatic sheet release for solo blue water cruising. I never said he shouldn't go to sea, I'm concerned his approach is wrong and I'm not going to endorse bad decisions to "encourage" someone. You can depower a 28' tri while you sleep and it will still sail well, but be virtually untippable. If you are off the wind retract your boards also.

    I get a bad link reply...fyi

    Seems like ocean crossing would be MUCH safer with a mate. I realize this strikes the OP; sorry.

    Potentially much more pleasant as well, but still not for me.
