how you secure your furler
I thought this deserved another thread, even though the "headsail furler" is
surprisingly civil so far. :) We all know (I hope) about giving the furled sail a couple of extra wraps with the jib sheets, but do you go further? I seem to recall someone (more than one) tying off the sail with an extra line, but I wondered at the time how one gets up high enough to make that effective. I use a shackle on the drum of my Schaefer. Anyone else? http://picasaweb.google.com/SailNOW....31504561647202 -- "j" ganz @@ www.sailnow.com |

I add the sail tie whenever I "stop" anywhere. That way, it's part of the routine, and I don't forget it. That also means I don't forget to untie it before taking off, which could be a real inconvenience at times, especially when single-handing. |

The best thing to do if a major storm is coming is to remove all sails from the rig. A poor second best for a roller furling headsail would be to wrap the spinnaker halyard around the sail, which should prevent if from unfurling. |

I have to emphasize this last. The Chesapeake can deliver squalls in excess of 100 knots. There is essentially zero warning. Dockmate had his genny beautifully furled with 4 wraps of the sheets holding it in place. Squall got under his furled sail and unwrapped it like an anchovy tin.

It's a lot easier to put more tension on a jib sheet, which could lead to furling line failure. For an example, a 5/16" StaysetX furling line has a tensile strength of 3000 lbs, while a 1/2" StaysetX jib sheet has a tensile strength of 8500 lbs. Allowing for the mechanical advantage produced by the furling system[1] it would be hard to say which would fail first. My suspicion is that you would do major damage to your sail before either line would fail. I agree that loading up the sheets of a furled jib using the mechanical advantage available with a handle in the winch would be a bad idea. Ryk [1] In a typical drum system the torque loads will balance between the sail load and the furling line. When the sail is fully out there is no torque, thus no furling line load. When partially or fully furled the sail load will produce a torque of approximately the wrap radius times the sheet tension, while the furling line will produce a torque of the furling line tension times the drum radius (plus any remaining wraps of line). The result is that the maximum tension in the furling line is probably 1/4 to 1/2 the tension in the jib sheet and considerably less when the sail is only partially furled. |

It lasts a lot longer and would have to crawl back on deck and get itself out of its bag to do any harm. I don't understand why folks leave the jibs bent on when they are away from the boat or expecting heavy weather. For me, the convenience of being able to have the sail out and drawing 15 minutes after we've entered the parking lot outweighs the expense of once-a-decade sacrificial cloth. -- Jere Lull Xan-à-Deux -- Tanzer 28 #4 out of Tolchester, MD Xan's pages: http://web.mac.com/jerelull/iWeb/Xan/ Our BVI trips & tips: http://homepage.mac.com/jerelull/BVI/ |

Fair cop, although you have moved the goal posts a bit to consider the bending stress on the foil or the forestay tension rather than just the stresses associated with twisting of the foil. I am amazed that roller furling foils cope at all.. |

I don't disagree with anyone who goes to the effort of removing sails,
and even booms, in preparation for storms. I'll just throw out my personal experience, FWIW. For Betsy in '65 and Camille in '69 I had hank-on jibs which were completely removed. Main was left in place under its cover. No problems either time. Fast forward to '05. For Katrina and Rita in New Orleans, then Wilma in Key West, I had a roller-furling jib. I removed the sheets and bungeed the sail at several points, then tied the drum down. Left the main on under its cover. No problems. YMMV, Frank (just back to Seattle from a delivery from St. Augustine to New Orleans, behind Eduardo and before Fay. Hooray!) |
