I have no problem adding an open bridge version to the KD 860 range.
Why do you want the centerboard? The anti-vortex panels do their work. They did not work properly on the Oryx, because they were in the wrong place and too small. He did not consult me. I like his changes otherwise. I am no fan of the split rig's. The idea is good, but the fore wing idea like Flettner used and all Junkers aircraft and which are used on stol aircraft work on aircraft. The speed range is different. We do not start talking about Reynolds numbers on sails. If they have some effects, the effect is too low for the extra work and costs. Same for the wing sails on the Tiki. The only good semi wing which worked and was worth the effort and costs were on the junk from a friend. In principle was it a symmetrical wing section and a long flap. Made from cheap PVC tubes. Not too many trailing edge ropes, so no rope salad as usual.
I am always in favor of a clean and effective rig. So the rotating mast (rig) is the logical choice. What you are talking about wearing? The big grafit/Epoxy bearings on the deck give never a problem. What water? If there are some trips, the is no problem. Brian will you enlighten us, please?
