Australian SailGP race sailboat blasts by Queen Mary 2. The Cowes Regatta is this week. I think this is the first season of SailGP, racing 50' spec racers, with hydrofoil technology. This specific boat broke a new speed record last Saturday, clocking a 50.22-knot record. I would estimate that it's cruising in excess of 40-mph in this image:
