The third rule of tactics, beside sailing in more wind and sailing toward the mark, is to keep it simple. Keeping it simple means don’t tack or jibe too much, and avoid protests and clumps of boats. Try not to be the boat sticking it in at the weather mark on port tack layline, or the boat barging at the starting line or leeward mark.
Keeping it simple requires discipline and good judgment, and is crucial to doing well. To help make solid decisions I like to visualize a scorecard of all low single-digit numbers, meaning no “letters” like OCS or DSQ. When thinking about your regatta, picture a clean, almost boring event. No drama, just good starts, big lanes, and clean mark roundings.
