Doyle Detroit is proud to announce our partnership with SV Energy Solutions to design and build vertical wind turbines. In initial test in 15 knots of wind looks the results are very promising. We have subsequently improved the design of the blades and increased the performance.
IRC Upwind Asymmetrical with battens that sets on the head stay. TP 52 Trader. This is a first generation sail. Trader had her best upwind leg of Key West Race Week using this sail. As the picture shows, there is plenty of room for improvement in the design but the concept definitely has merit. New IRC Notice 2007/1 states that this type of sail must be declared with measurements.
