In dinghy sailing, you’re in a partnership with the person you sail with. It’s not about you, but about what the two of you--or three, or four, with heavy crews--can achieve. If your skipper never has to ask you the time, or for water between races, or to come up an extra half inch on the rail--because you’ve already told them, or opened the water bottle and handed it to them, or moved slightly to keep the boat perfectly flat--then you’re reducing the stressors and factors that they need to spend their brain power on. Your skipper’s needs should always be of paramount importance, and you should always try to be a pleasure to sail with. The right attitude and a little bit of psychiatry in the front of the boat will help your team succeed and make you a more desirable crew.
