sails look great but it's a different sail plan!!
i presume they are the same sail area?
how well have they been tested against the old sails?
it would be a shame to split the fleet if they prove to be an advantage. |

No, they are actually a bit bigger!
We have been testing sails since last year. Only got the hydes at the beginning of the year but the committe have decided they are by far the best option for the future of the class of the sails we had to choose from. If we didn't choose there would be no sails this year, again. They have been tested against old sails and gave a similar performance.
If they prove to be an advantage we are going to have to buy a new set earlier than expected, however from our testing it will still be the skill of the sailor that is the biggest factor. This is a far better scenario than them proving to be a disadvantage and everyone wanting to hold onto their old ones for open meetings.
Having sailed with the new sails I don't feel I have to rush out and buy a new set. I would certainly like some new ones though- it is my birthday soon afterall

call me old fashioned but if we are one design racing we should all have the same size sails.

Hi, it would probably help tracking the performance of the sails in the results area...
As you track if a boat is sailing with or without wings, knowing if it is sailing with sobstad or hyde could help keeping track of their behavior....
Anyhow my compliments to the tech committe for the work done.

Ian, you say that they are actually bigger. Is it just the main that is bigger or are 3 sails of a different area to the old ones? Thanks for all the work, they look great. Can't say that performance will be that big an issue unless anyone can honestly say that they have done a race without making any mistakes and that their position was largely dependent on how good their sails were. Bearing in mind Pete won the nationals with a main that i could see daylight through!! |

Of course the Iso is still a one design class, the sail has only been updated due to problems with the previous supplier. You have to expect minor changes otherwise we are all on a road to nowhere.
I think the sails look great and everyone on the committee have done a excellent job in sorting out the sails. Well done. |

There were many an order put into Sobstad for sails. How many times were they delayed?
Supply is the main issue throughout all recent developments of the class.
If you want on design - go 49er - oh even that isn't one design!!!! |

The size increase is due to Hyde designing the sail based on the dimensions of the boat, not by comparing it with the old one.
It is the main that is increased slightly but it is only a small amount. The sails perform as well as the old Sobstad sails. Whilst people are using both we hope each will be competative.
Kite in the picture is larger but the supplied hyde kite will be as the existing one.
It is a one design class but it was felt by all it was time that the boat needing updating to make it desirable again. There is no way new boats are going to be sold with this, and without new boats the class would die out?
Whilst we had to get a new sail manufacturer it was unanimously agreed that it was a good time to revise the sail. We feel this is the right decision for the class and fully intend to keep the class one design. For anyone is not convinced come and see the sails at the dinghy show and I believe W&W plan to have an ISO with new sails for test sails at the Chew event in April. I am also sure it would be possible to arrange a test sail at other times too after the dinghy show.

The concerns about variations in sail performance occupied the Tech Team's deliberations a lot prior to requesting test sails from anyone. Should we go single supplier ?? Multi supplier ?? UK manufactured ?? Chinese ?? Maximise the performance, keep it the same ??? - or a host of other options.
The intitial Tech Team brief was to find sails of as closely similar performance to the latest Sobstads as possible. There is every indication that objective has been achieved.
The existing range of Sobstad sails in use was just as much a consideration. There are very old 199x sails achieving respectable results, "daylight" mains winning the Nationals and the newset Sobstad design looking and cut very differently from the model of only the prevoius year. Bottom line is that we already have a lot of different designs out there anyway and all from the same manufacturer over which none of us have had any say let alone test before release - yet we still regard the ISO as a one design. So it's pretty hard to judge the existing sails against eachother let alone a new manufacturer's set.
New sails will always perform better than older ones ( so the experts tell me ). Nevertheless the Tech Team have tested the sails on different boats against Sobstads and the other offerings with different set ups then swapped crews around to compare. Their conclusion is that there was little difference between them. The price is also the best on offer.
Unlike previous sail changes, at least it's one which the Class has driven and made the choice. Is it the right one ?? The next year or so will tell.
It's a brave new World for the ISO and Buzz - and I'm ***really*** looking forward to it !!! See you all at the Dinghy Show at the end of next week to take a look at the tremendous Tech Team work - matched with new hull and spars.

Have done a lot of the testing of the new sails I would echo the view that the Hydes are the best choice. Yes the sail plan is different. The sail is cut much flatter and is a much more modern design. This should mean we can get away from pre-bending our masts so much to take the fullness out. Being radialy cut it should be easier to repair when the crew jumps through it.
I have also used the all the sails in club racing. The hydes overall performed better in a broarder range of conditions. I have race in lightish winds and force 4-5. I won when I expected to and the only noticable advantge I gained was using that oversized kite. The one point of sail I have stuggled on is a two sail reach, and I need to perfect how to sail that with these sails. The Sobstads, being so full in the cut, give you a huge amount of raw power. These sails are more refined.
Like the others who have been test we are looking forward to this coming season, and I have decide not to invest in an RS800 but replace my antique sobstabs for the more modern Hydes. |

Hi Richard
Great to hear you are staying with us, I don't suppose the new sails stopped your ability to sail straight into the wind  |

Its great news to hear that crews can now jump through the main sail without causing too much havoc. Anyway I thought that one of the main purposes of having a one class design is so that the class does not become cheque book sailing. And with regards to the sails this is true because we can only buy one sail design from one manufacturer. Its not as though you can pay more money and get a better sail everyone has to buy the same. Also it would be very hard to test the new sails properly unless you had a good selection of brand new Sobstad sails to compare against, of course with the boats being sailed by the same person. New sails whatever the brand, or breed generally help the boat go faster.

This is the first time i've seen a photo of the new sails, they look brilliant !! they Make the boat look much more up to date. Can hardly wait to get our hands on a set
Many thanks to all involved !
