California Code, Harbors and Navigation Code - HNC § 282

Sailing vessels, having the wind fair, shall give way to those on a wind. When both are going by the wind, the vessel on the starboard tack shall keep its wind, and the one on the port tack shall bear up strongly, so as to pass each other on the port side. When both vessels which have the wind large or abeam meet, they shall pass each other in the same way on the port side. To effect the two last-mentioned movements each shall give right rudder. Steam vessels shall be regarded as vessels navigating with a fair wind, and shall give way to sailing vessels on a wind of either tack.
