Posts: 548 MERRITTISLAND, FL | You have a class in it's infantasy, with a hand full of boats being sailed around the world, still looking for main player manufactures to get involved,you have countries with out associations, a country with 20 boats sailing under the radar and there is talk of adding a wing to the rules.
It dosn't even make interesting reading.
TJ A bit harsh but true. None of this has any real relavance to the Class organization, and presents a real deterent to the continued growth of the class. Being at least partialy involded in all of these options and being someone who is interested in their potential, someday I would like to find the time to dabble myself. But, I would not want any of these things incorporated into the F16 though as it does not make sense. To really make foils an advantage, the beam is way to small on our boats. To gain any real advantage with a wing both the beam and water length are too small. To have a 2 man boat that has good pitch numbers the length needs to closer to 18 feet. All of these items point to an already existing class - 18SQ If you guys really want to dable, you need to dirrect your verbal efforts on reviving this class. Matt | | | Re: F-16 wings..

Also expensive mess.!!

Posts: 9,582 North-West Europe | In real world, how much faster would a wing make an F-16 upwind?
Very preliminary but here is one comment that answers your question (as taking from the latest A-cat race) : >>The wing didnt win, although Ben is very fast. ... . He didnt capsize and on Sat when it was >>windy and puffy I was pacing him upwind on the first beat. Once we went around the top mark he >>was gone, way deeper and faster. He said later that upwind he was pinching and needed to put the >>bow down and go. Source : http://www.catsailor.com/forums/sho...umber=119992&page=0&vc=1If this is indeed true (which need far more testing to determine) then this may actually mean that it is not attractive for F16's. Afterall we have the spinnaker for downwind work and we already go very deep and fast there. A fuller wingsail with slots won't do much then as the spinnaker is rotating the apparent wind over the mainsail to almost an upwind setting anyway. Also the spinnaker will be providing 80% of the power, thius implying any mainsail gains are devided by a factor of 5 and could well be negligiable in the overall picture. Since the wing dont have a mainsheet, just an AoA adjustment,
Personally I believe this to be actually be a DISADVANTAGE of the wing sail. A sailor sheets the mainsail out to reduce power and lifting. Letting out the traveller instead will also work but many have found that this looses too much drive (and speed) at the same time as well. Try it yourself on your boat. I mean controlling the heel with the mainsheet and then with ony the traveller. When using the traveller you'll be losing pointing ability and speed every time you travel out. I don't see how this can be different with a wingsail. Basically as will all new concepts. You get advantages ONLY at the expense of a set of disadvantages. If the first set is more important in achieving your end goals (win a bouy race) then the development is succesful. Otherwise it will fail. Also what may be succesful on a spinnakerless A-cat may well not be succesful on a cat with a spinnaker sail. All very interesting. Wouter

Basically 10.000 USD for a wingsail.
A soft sail rig costs about 5000 USD.

Would you order a refined and delicate piece of equipment like a wingsail with a 1 USD/ hour labour force ? Wouter
