Sam Varner, former trainer of US Olympic teams, is his book "Slimmer,Younger, Stronger" writes about breathing, fluids, food, sleep, exercise, thought, and the power of prayer.
Sam is spiritually motivated and suggests that you pray to God twice a day about your goals. Write them down on a little card to carry with you, so you won't forget.
I am not sure God cares about your sailing, but if you continue praying twice a day for better sailing, after a period of time I wouldn't be surprised if it worked.
