    Not any American C-Cat with a 360 rotating wing in the LAC history ?

    The slotted wing presents some advantage in very low wind, where you seek deseperatly for more HP in your rig. But with today's apparent wind on the A-Cat (i.e), the slotted wing is an hudge extra complexity for a very slight advantage. Sailing at 20 knts down the wind with 12 knts TWS will provide you with around 20 knts apparent wind Windward in the same conditions, if you flioat you will have 22 knts AW, if you foil at 20 knts you will have 25/28 knts AW. In both cases you are overpowered, even if you consider the max righting moment hypothesis ( =the lift on the windward foil assumed to be 0+ full trapeze crew). The slotted wing would be most usefull in light wind conditions, unfortunatly in these conditions the Reynolds number of the air stream on the wing is half the Reynolds numbers on a sail+teardrop mast, which probably contributes to offset the theorical extra power of the slotted wing. Regarding the futur of the A-Cat rig or all other foiling boats, I would believe it will be all about drag. Cheers

    As a professionnal sailmaker Randy tried a jib+reduced mainsail on an A-Cat, but it was probably because the original mast of his boat was not stiff enought for a normal sail, so he cut the mast and put a jib instead of buying a new rig set.

    a significant part of the load on the mast comes from the frontstay where the leading edge of the jib must be maintained as straight as possible. The compression resulting from the little mainsail remains a bit mysterious too me, probably lower than for a classic sail+ small teardrop mast with similar area ??? But its aspect ratio is so high that I am a bit confused on this point (Double aspect ratio but half area) Or the tension to hold the leech = the tension to hold the jib ?? more or less Just an assumption any idea?

    I think the 360° works fine when the main sail is down, so in very strong conditions, otherwise you do not need a 360° rotation, but in the harbour for happy hour

    At first glance it seems that this wing/sail concept enables 1- To change sail area to some extend 2-When no more soft sail area to be roll down, the remaining mast -is less draggy than a bare classic mast, -and it can feather in the wind at 360° While it might look trivial, I think this trade-off is a great achievement.

    Surprising to see forum anarchists to spend more time answering crappy DL genius allegations, than putting their brain at work to elaborate interesting questions regarding this "made in USA" innovation. The radio interview is not very clear for non native English anarchists, that is whY the only point I believe I understood was the 360° rotation, but I did not notice any comment regarding the lift, the drag, the relative performance vs a classic teardrop mast+ full batten sail rig. It seems to be an application of the Tom Speer workpaper with a teardrop mast at 50% sail chord ?? Congratulations &Cheers

    ita, You wrote : "Seems that you know well M. M. and his boat," If for you M is the designer, builder or promoter of the iFly15, I am sorry I don't know him and did not exchange any pm with him yet. When you wrote :Ask directly to MM which evil destiny had its S9 that he bought from me, You are explaining me: 1-He is one of your former customers, 2-He bough a S9 from you, and 3-He has some issues with your boat Then, like everybody else I can observe, he has been studying and building an alternative to your S9. So you probably realize your message is carrying a lot of information. Starting such a project after some disappointing experience with your boat, provides insightfull indication with the level of disappointment! You claim you are different from bimare, but: Ostracizing your customers who had reliability issues with your boats, discarding their sailing skills to explain the breakages of your stuffs, sounds pretty familiar to my ears. It has been your "Client Servicing" philosophy for your A-Cat during 20 years, with .........."mitigate" results. If you sell to the US Customers what you have been selling to some of your European customers, you might have big surprises: US customers are not European customers and they will not hesitate to hire a lawyer to kick your ass. Your rig design is also carrying a lot of informations on your skills: it just testifies you did not compute the apparent wind of your boat in foiling conditions! To address this point you should check "trigonometry" on Wiki it cannot be harmful.

    ita, I must confess It was a little "ambush", as I know you cannot resist to "defecate" **on your concurrents, this new iFly15 was a perfect opportunity to trigger the "action" As a side effect it is funny to see Doug Lord taking care of your interests, but believe me, on this point, it is purely unintentional
