4. Always demanding your starboard rights.
You're on starboard, on a lift, or, for some reason, you're determined to get to the left side of the racecourse and a port tacker is coming. How many times have you gotten worked up and felt as though you had to enforce your rights by yelling, "Starboard!" as loud as you could, only to have your rival tack on your lee bow so perfectly that you're forced to tack away? Once you tack, you're on a header, probably sailing to less pressure and away from the best side of the racecourse. In a situation such as this it's usually better to let the port tacker cross. If you want to get left, wave them by. Tell them they owe you one and sail for the good wind or current. It may feel strange to let them off the hook so easily, but when they cross and later tack to weather and behind, you'll feel better about letting them go.
