That is one of the first "rigs" I asked Rob about, years ago. It goes back to 2001 Elkaim's thesis http://www.soe.ucsc.edu/~elkaim/Documents/GabrielElkaimThesis01.pdf . I was patiently awaiting Morelli & Melvin's version of the Elkaim offschoot, Harbor Wingtech wing http://www.harborwingtech.com/products_recreational.htm
I understand better now why it may be easier to have this on a small drone or on a large ferry doing SF Bay than on a cruiser vis for an reasonable price. I might settle for this though
