Put it all in the bag, stir it around a little, try and get it exactly right and then give your self time for a practice launch before the first race as I bet there will be one or other little thing wrong to sort.

Quite interesting putting your boat head to wind, running to the front of one or other bow, balance on one foot whilst leaning on the bridle, wrap one arm around the forestay, unhitch what ever is the problem , and then get yourself back to the tramp before the boat turns downwind. I'm well practiced
