These rules are used internationally, and are also enforced by the United States Coast Guard and local agencies. You should be aware of these rules, and follow them whenever you encounter another vessel on the water.
General information ed area must yield to you (they are the GiveWay vessels). Both you and the meeting vessel must alter course to avoid each other. that you should maintain course and direction, provided the other vessel gives you the right-of-way as it should. Meeting If you are meeting another power vessel head on, and are close enough to run the risk of collision, neither of you has the right-ofway! Both of you should alter course to avoid an accident.
General information from local marine supply stores. Fishing vessel right-of-way All vessels which are fishing with nets, lines or trawls are considered to be “fishing vessels” under the International Rules. Vessels with trolling lines are not considered fishing vessels. Fishing vessels have the right-ofway regardless of position. Fishing vessels cannot, however, impede the passage of other vessels in narrow channels. Sailing vessel right-of-way Sailing vessels should normally be given the right-of-way.
