Hi there, what about use a furler to close the spinnaker ? here are some F16 that have this system and is pretty fast and easy. Any idea ? |

It doesn't work well with a furler. That's probably a hooter or screecher you have seen. Spins have too much shape to be furled |

x40 catamarans has spinaker with a furler and while upwind sailing they lower it on tramp see vid in time 1:32 [youtube]http://www.youtube.com/watch?v=HZCAOENJ_9k[/youtube] I think it could work good with small spinaker too. |

Hi, Yes ... we "multihullers" would call that sail a spinnacker .... but most "monohullers/sailmakers" would call that a "screacher or jennacker" .... since it is a fairly "flat" shape .... ... especially if the clew was cut just a lil' higher ... |

It could be done but the extra drag to windward, especially in light air, would be dramatic. You would also lose the ability to adjust sail shape as the clew is fixed at the furler. There are times when trying to make a mark that letting the clew out a bit allows a better angle. Uphaul is also fixed on the furler and would prevent any adjustment there to create a fuller sail. Typically you sail with the luff hard and clew at the pole end but the ability to adjust each of these points is important on a race course. |

Nice system but it is shown on a bow sprit, not a 12' spin pole. Still remains up continuously as there is no way to launch it from the deck of a beach cat. It will create wind resistance and slow you down going upwind. Whats the advantage over a mid-pole snuffer? None that I can see! What does it cost compared to a mid-pole snuffer head and sock, still need the pole either way? Mono hulls have furling mains as well, is that the next thing in beach cats? I don't think so

In my 11 years experience on the pointy end flying an asymmetrical J109 chute (100SM), the sail shape is always adjusted from the tack line at the bottom. Easing the tack will create a fuller shape up top when driving deeper. The same holds true for a Hobie. Easing the halyard only allows the chute to blow off to leeward, creating an unstable kite. There's no gain and a lot of loss from that. |
