??? One aspect of the KD 860 that bothers me somewhat is the lack of any sort of sacrificial "beaching keel".? With either the AV panels, assuming that they would work with a very sharp chine, something nobody hear has related accomplishing (making them work at all), or Bernd's single pivoting centerboard, or luff boards, there really is nothing but the hull bottom to take the abuse if one beaches the boat.? Pete's low aspect ratio keel on Oryx should provide at least something for the boat to stand on.? The only photo I've seen of these keels is the one below, and they seem to be aft of the CG.?? Interestingly the forward end of the boat appears to be solid decked....... something I had not observed before, and something I do not like at all.? One aspect I liked about the KD 860 from day one was the fact that the bridge deck began well aft.

??? It was discouraging to me to see the AV panels more or less abandoned as unworkable for the 860 in this discussion, but at least the two solutions do not sacrifice the shallow draft that is so attractive.? It's an unfortunate fact of life that designers like Bernd do not net enough from their work to be able to do a lot of R&D.? I can't imagine plans sales even paying the bills.? It's not like the America's Cup where people with hugely deep pockets and throw millions in to R&D.?? That makes it largely a collective effort between designer and builder, and in many ways that's a good thing, and I'm deeply grateful for men like Bernd who labor designing boats out of love for boats, and give so generously of their time, to make these boats a success.? I've often asked uncomfortable questions in my posts, but my intent has been to promote free discussion and view and understand this design that has captured my imagination as honestly as possible with all it's brilliant innovation as well as it's shortcomings, and their solutions.??? As a man who has engineered and designed quite a few complex systems, and built them, I know how it works, and things I've built that I thought were bullet proof have often needed revision.?? The things I've designed and built are NOT floating on the oceans of the world, but harvesting crops in the field.
