Joe, I think you were spying on us at our club last weekend. I used the spin halyard and mainsheet blocks attached to the back of my truck to pull the mast forward enough to get my forestay in where I wanted it!
Thank you Joe! You honoured your promise, which is fair. Much appreciated! And... I gave a “like” because I actually liked it (and _also_ because it is fair ;-)
Thanks, unfortunately i don't have a Hurricane here, the closest would be the Tiger. Here are a few that might be close: F18 style Mast rigging ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-8QXFGx2D2kw.html Raise the tiger mast ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-d1SkvKeY180.html F18 mast set up Pre Bend ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-_WVNaMW-Dy0.html F18 mast set up Rake ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-uDjDZ8OSr64.html F18 mast set up Rig tension ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-_mOp7-ANALM.html
I used your technique by tying the traveler with a line running under the hull and tied to the other side and worked like a charm . Brilliant info as always. Thank you. Question ….while the boat is on the beach for a couple weeks or so, waiting for me to come back and play, do we release the rig tension or keep her tight ?
I'm so glad that this was helpful. It's certainly going to be kind to the boat to release the rig tension - maybe just by one or two holes - so that the mast doesn't flop about in the wind.
On my Boat (not a catamaran) we use something called sta masters you tighten the nut and it tightens the shroud, I would think it would be easier to tighten your rig using sta master.
Yes, on some of the cats we have a similar tensioning system. Hobie and most manufacturers supply these chain plates as standard (probably much cheaper)
Interesting! Do you have any suggestion for the diamond wire tension? Also, you might gain a bit of precision on the "solo method" with the ratchet turn off, so that you are measuring the tension on the sheet without the block friction in between. Maybe it does nothing, but could be worth checking.
How did you settle on 26-27 as the proper number? I think that works out to 170kgs of tension. The old Tiger guide said run it loose, basically, take on the slack, and then increase slightly as the wind builds. Goodall recommends 50 kgs in the light gradually increasing to 100 kgs in heavy wind. Just curious how you came up with your #.
On the Tornado the guidance was to run more rig tension in lighter air, less in moderate/high winds. Theory was to keep the forestay from sagging, affecting jib luff, when keeping the main sheet slacker in light airs. Having main too tight in light air just hooks main leech to weather, which is very bad. So running light main sheet load, the rig tension keeps the forestay tight enough for the jib to perform well.
Those numbers have always been the go-to settings on the F18s - back from when Mitch Booth ran a training clinic at the first Tiger Worlds in 1999. I've also been training with Danny and Kostas (current Tornado World Champions and 2nd in F18) They are running the same kind of numbers. BTW that is the black Loos Gauge not the silver.
Hello Joe, I am getting my SuperCat 20 mast ready for my trimaran. It is a double diamond set up. I have some general tensioning instructions from Aquarius (the original builders). How do I roughly measure the tension of the diamond wires? I am thinking of making a primitive lever tool, this should allow me to at least measure relative tension .... any suggestions would be welcomed.
