He always hates it when I post a pic of his early efforts with the Sport, but I love his technical expertise at being the first to really push and perfect sailing the Hobie Mirage Drive yaks. He has now moved up to the A.I., so I expect to see some new advances there also when sailing conditions improve sufficiently in the frozen Northlands.
