I learned a valuable tip from watching/listening to Jacques Bernier. The step-around-the-beam trick as the boat rights is, IMO, invaluable. It puts someone on the boat instantly to control sheets and rudders, and as a result dramatically cuts the amount of time it takes to get back in the race. It requires teamwork and one of you has to be willing to get wet, but I have found it to be so much easier to help the other person back onto the boat after it is under control (e.g., not dragging the person in the water).
Also, a lesson learned - with the extra freeboard under the front beam on the Infusion and the Capricorn, it is MUCH faster to get back onto the boat from an aft position. If upper body strength or fatigue is not an issue for you, then by all means climb that hill.
Last flip - Spring Fever 2007 with Tina Pastoor at the C-mark on the Cap with the 'chute up. Last close call - Melbourne YC, 2007 with JC just after the A-pin on the Blade just after the set.
