Hi Steve and everybody ! Let me try to define the diference between the light 140% and light 108% in light wind (2-3 knt up to 10 ) ! One important factor is the curve ! In low wind speed we need bigger curve (A) . Second to have a sail "working"we need it to be in "shape" (B) . A light sail is made of light matterial and the smaller surface the easier to get proper air flow all around it get shaped and start "working" !So an earlier acceleration will give an apparent wind etc. The bigger sail even of the same matterial is in total havier and so more difficult to get in shape . At the same time thinking of the polar diag. Waiting for comments ! Nikos

Hi Nicos and Steve
I have been racing here in Norway with both a 150% Genoa 1 and a 107% Genoa 3 (Quantum) on my 370 the last two seasons. The genoa 1 has been good, but with experienced optimum performance only in range 6-12 kn TWS. In less wind it has been challange to get good performance and in below 3 kn TWS the sail is not keeping shape and needed "twist". The heavy genoa 3 performs well in range 8-20 kn TWS and overlaps quite much with the genoa 1. In winds above 20 kn TWS I have a flat and heavy fock which is a very good sail to use in these conditions. I have not felt the genoa 1 has given me the needed extras compared to the punishment in rating ("LYS" here in Norway). Have also experienced that the genoa 3 is performing very good in light winds below 4 kn TWS, it is keeping the shape very well due to battens. Therefore I have this winter sold the genoa 1 and ordered a light genoa 3 (still Quantum) to cover the range 0-10 kn TWS. This to be delivered in March sometime ready to go when ice and winter is gone. Looking really forward to try the new sail together with timmed rig and clean hull! |

Bjorn, thanks for the information and input! We definitely agree on where the maxi-jib start to perform ~8 TWS.
Do you have further information on the 150% that you had? cut, material, manufacturer, etc... It will help me decide if I'm going down the wrong path with my 145%.
Thanks for your help, Steve Edited by Rubato - 29 January 2009 at 18:35 |

Hi Again
First of all this is my own decision on basis own experiences and results comparing with other boats. I have discussed this theme with Quantum here in Norway of course, and together with other sailing friends. An important part of my decision have also been to get same rating as other Hanse 370e's, as few have a max-size genoa 1. The sail was a Quantum Fusion w/ carbon 150%, almost too long to genoa tracs ... . As I said above - in optimum conditions the sail was great, but very often conditions here are either in the upper or lower range which genoa 3 performs good (or better). |

Sounds like you had the same sail as that which I'm ordering except yours was 150% and I'm going 145... One of the reasons I'm going for the 145 (Versus 150) is the length of the genoa track... unfortunately, here in Vancouver the wind is rarely in the 10+ TWS range. Quite often the race day will start out in the 5 knot TWS range and the 108% just doesn't cut it. I don't expect to be competitive with such a heavy boat when we get down to 3 or less no matter what sail is up. |

Just a quick comment here from another Hanse racer in Vancouver. I have a 371. We have raced not too seriously but have wond quite a few. I bought a 149% Elvstrom Genesis genoa after realizing we couldn't keep up in light airs. This was the biggest sail that we could get without excess rating penalty (PHRF rating).
With that sail we are very good upwind in any wind condition and have beaten quite a few ultra light boats once we get going. A pain to tack, and easily overpowered in about 16 knots true. Fabulous on a reach. Too bad it never seems to happen in a race. We use a regular code 5 spinnaker with factory alloy pole. This also fits as a whisker pole for the genny, a bit too long for the working jib. Last year I bought a new self tacker, also Elvstrom, and it does make us faster in all airs than before with the crappy factory jib (East Sails). I have only used it in one race, plenty of wind and we cleaned up. The biggest nuisance of having 2 jibs is changing them, it takes too long to do during a race. Also finding room below for the genoa in its bag. It is huge! Edited by gshannon - 11 February 2009 at 01:46 |

Thanks Grahame, good information. Do you just have the one spinnaker? I'm currently doing an evaluation on the sail inventory in preparation for the Van Isle 360.... Concerned about just having one chute and was considering a smaller/heavier one in addition to the 3/4 oz. It's been suggested I should look at the addition of an Asymmetrical.
