Hello everyone, I am posting this on behalf of a 320 owner in Australia. The simple reason is that he is 80 years of age and is not too computer literate but boy can he sail!!!. He races nearly 4 times a week and has posed this question, hope you can help out.
“Hanse 320 – We have been racing using a Dacron No. 1 ,105% - ok over 10 knots but we struggle in the light winds. Does anyone know if a Mylar or similar light sail is more effective in the very light winds? Presumably will still be 105% because of shroud positions.” Many thanks for any help you could provide. Best regards Sparksey |

Light wind performance is a typical issue for Hanses. I offer the following advice based on the experience with my 400....
- a 105% mylar sail or other type designed specifically for light winds will be a little better than the Dacron but not worth the expense in my opinion.
- you really need an overlapping genoa. I have a 140%. This % was specifically chosen by my sailmaker so to fit around the rig (spreaders and shrouds) so that pointing angle would be compromised as little as possible. The pointing angle does suffer but the gain in speed is worth it
- the other thing one can do is maximize the main sail area as well (more roach for example). Depending on the handicap system applied, some roach can be added without penalty (e.g. PHRF)
Hope that helps

Rubato...I think you should know already that what's possible in a 400 isn't suitable for a 320...108% is an absolute maximum overlap...which still isn't perfect..a 105% works better according to many people that use it...the only way you could significantly improve low wind performance is a Code 0 upwind and a Spi/Gennaker downwind... |

that would be why I said it's only based on my 400 experience, i have no idea where the shrouds are on a 320 or if there are (or could be attached) tracks and cars for a genoa.
However, Sparksey also posted in the 320 forum and pretty much everyone has the same advice as myself. So,if the 320 can't handle an overlapping jib the obvious conclusion he will come to is that only very small improvements are possible. Even going to a jib with roach and battens is only going to add a few % of sail area (up to 108 as you mention and that is what I have).
A code0 is certainly another option BUT is not going to provide the pointing angles of jibs. I'd talk to a sailmaker about what to realistically expect before deciding that's the answer.

The shrouds unfortunately are set at hull width so there's no way around... I have genoa tracks insalled by factory and I already used them with a standard jib which works much better and holds it's shape... A good code 0 certainly wouldn't point as high, but sometimes you better give up a few degrees of angle, but win some kts and defeat the competition...it definitely depends on the type of racing... if you need the best pointing ability...I would definitely go for hi-tech sails...the dacron simply cannot point the boat as high and fast upwind... If you are ready for some hardcore improvemnts...there's also another possibilty (a friend of mine did this on his boat)...you install a permament stainless steel bowsprit with a waterstay...my friend has got a 1m+ bowsprit...and guess what...he moved his forestay all the way forward and it is now fixed on the bowsprit...the result is a much bigger jib which would pull almost as good as an overlaping genoa...besides, with a Hanse you can still use the selftacking system... This is pretty complicated however not to mention the cost.... Edited by Windsurfer - 16 July 2011 at 21:38 |
