Safety information5slow down or change directions briefly andpass behind the other vessel. You should al-ways move in such a way that the operator ofthe other vessel can see what you are doing.“ The general prudential rule ”This rule is called Rule 2 in the InternationalRules and says,“ In obeying and construing these rules dueregard shall be had to all dangers of naviga-tion and collision, and to any special circum-stances, which may render a departure fromthe above rules necessary in order to avoidimmediate danger.”In other words, follow the standard rules ex-cept when a collision will occur unless bothvessels try to avoid each other. If that is thecase, both vessels become “ Give-Way ” ves-sels.EMU25521Rules when encountering vesselsThere are three main situations that you mayencounter with other vessels which could leadto a collision unless the Steering Rules are fol-lowed:Meeting: (you are approaching another ves-sel head-on)Crossing: (you are traveling across the othervessel’s path)Overtaking: (you are passing or beingpassed by another vessel)In the following illustration, your boat is in thecenter. You should give the right-of-way toany vessels shown in white area (you are theGive-Way vessel). Any vessels in the shadedarea must yield to you (they are the Give-Wayvessels). Both you and the meeting vesselmust alter course to avoid each other.MeetingIf you are meeting another power vessel headon, and are close enough to run the risk of col-lision, neither of you has the right-of-way Bothof you should alter course to avoid an acci-dent. You should keep the other vessel onyour port (left) side. This rule doesn’t apply ifboth of you will clear one another if you con-tinue on your set course and speed.CrossingWhen two power driven vessels are crossingeach other’s path close enough to run the riskof collision, the vessel which has the other onthe starboard (right) side must keep out of theway of the other. If the other vessel is on yourright, you must keep out of its way; you are theGive-Way vessel. If the other vessel is onyour port (left) side, remember that youshould maintain course and direction, provid-ed the other vessel gives you the right-of-wayas it should.
