The factor between tilted and horizontal wing is cos(angle), assuming it's the same length

Hi Andinista,
You are right about that, but to be picky it is not only about cos when you tilt the wing. If going for an extremely steep tilt like 45 degree, which is typical of the beachcats with fixed wings, compared to horizontal, you loose 1-0.707 times the wing width in righting arm. On a horizontal(or just above) wing you can also change your body CoE more easily by hiking with your back more to windward like with a trapeze, ie the the more tilted the more upright you sit with your back.
My idea was to mimic the position you get when using trapeze. But also get some righting arm. In the position I sit on the first image I get about 20cm more leverage compared to trapeze.
Having tried angles from to horizontal I have found just above 10 degrees works best. When going horizontal it´s a pain to rise up from your comfy position even though I have left the trapeze handles on the the wires ;-) .
In purely mathematical terms the differencies might not be big, but you get the feeling of a more stable and balanced ride the lower you get.<!-- editby --><em>Edited by revintage on Sep 29, 2017 - 11:55 AM.</em><!-- end editby --> [/quote]
