Rules of the Nautical Road The rules of the road are an accepted standard by which all mariners are to comply when operating a vessel upon the water. Basically the rules require that every operator conduct his/her vessel in a prudent manner, at a safe speed, while constantly maintaining a proper lookout by all means available. The Sound Signals All vessels are required to exchange sound signals when their paths will lead them into any close quarters situation. The following signals are prescribed for use by vessels when within sight of each other, to signal their intentions with respect to maneuvering: 1. One short blast - "I intend to leave you on my port side." Often this means a change in course to starboard (right). 2. Two short blasts - "I intend to leave you on my starboard side." Often this means a change in course to port (left). 3. Three short blasts - "I am operating astern propulsion." Usually means that you are backing down. 4. Five or more short blasts - commonly known as the danger signal and is used when either vessel doubts whether sufficient action is being taken by the other vessel to avoid collision. 5. One prolonged blast - the boat is leaving its slip. It is also used for indicating your boats presence when coming around a bend. (A short blast is that of one second in duration. A prolonged blast is that of four to six seconds in duration.) The Situations In the following situations we use the terms "Stand-on" or "Giveway". The Stand-on vessel is generally required by the rules to maintain both course and speed. The Give-way vessel is required to take early and substantial action to keep clear and avoid colliding with the other vessel. MEETING. In this situation both vessels will pass within close proximity to one another on nearly reciprocal headings. The rules require that in this situation both vessels should exchange one short blast and pass with sufficient room on each other's port side. In this case both vessels are required to give way. 30
