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...
