>a solid laminate is better< By solid laminate do you mean no foam or a single density foam core? To give some more information on the intended...
Following your reasoning there would be no explanation for the wildly different foam densities that exist ranging from 30 to 300 kg/m2. I can see...
I was pondering this for a while and finally tried to find any information on this. I could not find much which means this is either a stupid idea...
Thanks for the heads up, I wasn't aware of this. Did some quick reading on this and there doesn't seem to be complete consensus. There is...
The cross beam is very high above the water so the forces on the attachment points would be huge due to lever effect. On the ama is getting...
My bad, I stand corrected. An actual bow rudder on a kayak would indeed be quite stupid.
I am working on a center cockpit trimaran design with a sugar scoop back and a dinghy garage under the deck. So nothing can block the stern. All...
I noticed that the Omer sail seems to have a rather big gap where the double sail meets at the trailing edge. That may create a significant amount...
For reasons of budget, availability and simplicity I am going for unstayed free standing masts. Also I like the fact there are no shrouds. Less...
Thanks for taking the time to answer Blueknarr. Now my whole understanding of sail twist is out of the porthole.... I almost asked another...
I asked about wind gradient not because of twist. I know it is inconsistent. I ask because I would like to know how much difference, on average,...
I was quite surprised how hard it is to find actual research/measurements on wind gradients. Even Wikipedia makes a few claims and just mentions...
OK, I fiddled around for hours and think I found a way to change camber in my soft wing sail. It seem doable to vary the camber from let's say 7...
Is this a from a racing perspective? If cruising and half a knot more or less speed is not that important are the answers still the same?
I have another design for a sail that seem so work beautifully. I made a little model and tested it. It is a soft wing sail that reverses camber...
I am just looking at applicable slow speed airfoils. Do keep in mind that I have a rather fat unstayed mast. A stayed mast might be appropriately...
I just tried with a larger sail model and you are right. There has to be a better kind of connection with battens and leading edge. Just sail...
Thanks, good info. I need to explore this more and maybe do some tests. The limited amount of soft wing sails I have seen do without solid...
Just a luff pocket only helps reduce drag a little, but a big fat round mast is a poor leading edge. I propose to put something inside the the...
Hadn't thought of that yet, may well be. Because I am working on soft wing sails I am going unstayed anyway so the shroud attachment is not an...
