Alan, We have seen good sailing hull structures with only semi longitudinal unidirectionals at +/- 15 degrees to CL. Assuming semi fixed ends,...
Yeahnah... A couple of ideas, principles perhaps. 1. Not too difficult to test the vessel at 2x the intended pressure, unmanned. 2. Not too hard...
And after thinking some more.. 1. At this windspeed and approaching full heel, partial L/D optimisation rides along with RM utilisation. 2. Max...
Oops #2 ... and the traveller should be higher as well, so try above CL of 1 to 2 degrees...
Oops ... lower CE for given forward force
Remmlinger, Your inputs for the squaretop look a bit extreme, e.g. there is no way that the main twist difference is optimally almost 50%. Why...
Nice work Mikko ... Squaretop is great, but so much voodoo being attached.
Serdar 12% chord thickness ok at this scale. Make it 20% longer than the theory and test at low speeds.
Everbody remember.. Sailing is a simple sport (perhaps not so much) for simple people. That is, and remains, quite a good joke. Al, accept this...
Zstine A full feaso for medium speed cat ferry for Sydney Harbour suggested there could be benefits for a Swath configuration, but then decided...
U To be clear... Bolted through the local wall... Easy to do if you have a sheave box nearby or access via backing plate removal. Google '316 rose...
Also, just tidy up the existing welds after removing the bases. Alignment of the new gudgeon bases in the way of the welds should help the overall...
Lets call the new attachment fittings 'gudgeons'.... because that is more or less what they should be. If they are located (each pair) equidistant...
Three issues: 1. The properties of the alloy are reduced in the way of the weld... a bit like 'tear on the dotted line', so the weld functions...
It is moderately miraculous that the thing remains erect. The structural integrity of the tube is likely to have been compromised by what are...
Oops Add 1/2 draft to ce height as well for ce torque lver arm
Two ideas for guidance: 1. At 45 degrees of heel the aero force will about 30% less than the upright equivalent. 2. Calculate the approximate...
One pricing for exclusivity is the very simple x 2 But this usually time limited, say 5 years exclusivity period?
Listen to Admiral Halsey....
No Al Maximum sail force at maximum flow not stalled.
