Does anyone know companies/persons who actually design and build the wing sails for eg Americas Cup yachts? As far as I know none of the big...
You are quite right I have found. The official term is indeed 'eyebrows'. It also appears that a divice at the aft end of the tunnel is referred...
Thanks Daiquiri I already have had a civil engineer with cfd competence look at it, but his knowledge of boats is so limited that it was a waste...
I think it would be very interesting to do CFD analyses on this contraption. Does anyone have an idea who could do that and an estimated cost?
I have seen some yachts equipped with semi circular "lips" on the forward part of their thruster tunnels. See photo attached. Has anyone seen...
I am curious how 600 sqm's of fixed wing sails are handled when the cat/trimarans are moored. Does anyone know ?
Thanks Richard Woods, The most accurate reply I have had so far. And you are right about the complexity as well. My invention i a little bit more...
The 5% efficiency gain is based on the simulation across wind angles as the net effect of : side, lift, drag and forward forces
Even the AC designers have no idea of the performance effect 3DL sails have on their boats ! Only that they are lighter and more stable. So sorry...
Thanks daiquiri, Your answer suggests that not even the most advanced sailmakers have any idea of the performace gain of their various sails ?...
Just to challenge this forums participants: If I had been an America's Cup sail developer at say Quantum or North Sails (they do excist you know)...
Surely all of those smart guys at North Sails, Quantum etc. have tested and simulated, and know the improvement a 3DL sail has over a conventional...
Has everyone given up trying to answering my question ? How does sail efficiency translate into improved performance ?
The simulation was conducted in apparent wind angles of 28 to 40 degrees. In that register the performance incresed with the angle of attack....
Uuuuups, if I keep replying to all responses I will probably get the best posts/view ratio on this forum...... Could someone kindly help my...
Yipster, Actually, to my surprise, inflateable battens are a fact ! That turned up during the patent agency's screening:...
Dear CT 249 This is my first attempt in getting a patent and I am learning (spending) as I go along. You are quite right in your stements...
Ho CutOnce and others I think you and others are quite mistaken about the process of applying for a patent - and getting it. You do NOT need to...
Thanks Bataan ! I have actually already followed your advice, but in a sense in reverse engineering. Initially I tried the concept (not so much...
To Tim B What an attitude ! It is a simple question, and yes I am not an naval engineer, but if you as an expert, can't answer better than...
