Boat designer David Alan Williams is here for several days to consult with us on K2 design. Today was the first day of his trip, and we took K2 out for a tow test and to fly the new 30 sqm kite. Ann accompanied him and Don and Joe on the tow test, and David, Joe, and Richard took turns with Don for the kite test. The new kite worked well, as did the boat, although the wind/kite were insufficient for us to foil well. Before the test, Jamie completed the electronic ride-height controls on the tiller so it is now possible to adjust all three foils. We saw Johnny Heineken out on the water.
