It seems that Andrew shares the same opinion of Pablo at Ullman - Iseo. Sorry Wouter!
A lot of people are asking us the same questions at the moment, so we are writing something to try to give the answer. We started developing the sail for the marstrom Carbon mast back in march 2004. Since then we have made a lot of sails and done a lot of testing. We have had the actual mast here at the loft since September after testing in Sweden during August. The final testing was in Genoa last week where we found our latest design to have a really significant speed advantage over the earlier models. The sectret has been to get the right balance of luff curve for the built in shape. In this sail we had made the profile as fair as possible making the sail very easy to trim and sail with. The design also accepts very easily adjustments with the spreaders and battens. We think this is very important for the future. On this basis we have decided to make this sail the standard production for 2005. It is very clear to us we can make very big changes to this sail with the spreaders, mast rotation, and battens. This is much more significant than in the aluminium mast. We have tested right through the wind range and it was always very easy to get the shape and power we wanted, so for us that makes a good sail to sell for this mast. It is very easy to use, and that is actually the most important point for good racing.We have tested so much already, it is time to stop and just go racing. For 2005, we have done the work. Now we need to go racing and learn about sailing with this mast and how to set the boat up. It is really clear that the settings need to be very different. We have written a rather extensive tuning guide based on all we have discovered. This we be sent out with the new sails. So to answer all questions, the sail will remain standard for 2005. It is not easy just to come up with something faster as we have already tried and tested almost every thing we can. We are sure we go forward in the future like usual, but the big step for us is clearly made. Now we need a good season to see what we can refine, but after 12 test sails we can't see a 2005 sail being outdated so easily by a 2006 model.
