The demo sails on our test boat (First Series boats are sold sans canvas, since racing owners are bound to have a preferred sailmaker) included a main that was cut quite flat, and both the main and jib were bent on for the first time as the boat left the marina. Still, the boat turned in a respectable 6 knots over the ground in our light-air conditions and tacked through just under 100 degrees. Cracked off to a reach, we gained a knot or better. Later in the afternoon, closer to the Golden Gate Bridge, the breeze built into the high teens, and the boat settled in, then surged ahead with the puffs. As a side note, given the well-thought-out placement of nearly every piece of sailing apparatus, I found myself scratching my head over the location of the chart plotter, which the builder has located at about ankle level behind the portside wheel. It was difficult to read, and I could only imagine the position one would have to assume to punch in waypoints.
