Collision risk may sometimes exist even when appreciable bearing change is evident, particularly when approaching a very large vessel or a vessel towing or when approaching a vessel at very close ranges. Toggle navigation.

Here are the main navigation rules that you should know before ever stepping foot behind the helm of a boat. When approaching another vessel head-on, you should navigate your course starboard, meaning you will pass each other on the port side.
An indicator of a head-on meeting at night is if you see both side lights, green and red, of the opposing vessel at the same time. The vessel that has the opposing boat coming up on its starboard side is called the give-way vessel.
The boat coming in from the starboard side is called the stand-on vessel. The stand-on vessel has the right of way, and it is up to the give-way vessel to maneuver in a way that will avoid a collision.
You will know this at night if you see the red port light crossing from right to left in front of you. In that case, you are the give-way vessel and should maneuver to avoid collision. If you see the green starboard light crossing from left to right in front of you, you are the stand-on vessel and should continue your course. A sailing vessel using its motor is considered to be power vessel even though sails motor sailing may be hoisted. In this situation the sailing vessel with sails hoisted and using motor should hoist a cone forward of the mast to show that she is "motor sailing".
The overtaking vessel must keep clear. This also applies when a sailing vessel is overtaking a power boat. When two or more sailing vessels are approaching one another the tack they are sailing on determines which boat has the right of way.
The Chart Room Blog. Now let's focus on the previously introduced terms and definitions by introducing stand-on Vessel and give-way vessels. Stand-on vessels and give-way vessels each have specific responsibilities based on the situation, and this allows boaters to navigate waters together with safety and certainty. Stand-on vessel: The stand-on vessel is the vessel which currently has the right of way.
In the event of two vessels approaching one another, the stand-on vessel has three obligations. The stand-on vessel must maintain its current speed and course, keep a lookout and stay alert, and look out for and return any communication from the give-way vessel. Despite having the right of way, the stand-on vessel still must be ready to act, if needed.
Give-way vessel: The give-way vessel must yield and get out of the way of the approaching vessel. When two vessels approach one another, it is the give-way vessel's obligation to take early and substantial action to avoid a collision. We know the responsibilities of the stand-on vessel and the give-way vessel, but here's how to determine which vessel is which. Here are three examples which demonstrate the roles of each vessel:. If a vessel approaches one from their starboard right side, keep out of its way If one or both vessels are sailboats then this rule may not apply.
As a rule of thumb, if one is approached from the stern or port side then one is the stand-on vessel. If one is approached from the starboard side, then one is the give-way vessel.
A power-driven vessel is deemed the give-way vessel when approaching a vessel which is not under command, has restricted maneuverability, or a vessel engaged in commercial fishing.
If one is operating a power-driven vessel and approaches any of these situations, they need to take early and appropriate action to avoid a collision. A sailing vessel is deemed the give-way vessel when approaching a vessel which is not under command, a vessel with restricted maneuverability, or a vessel engaged in commercial fishing.
Any vessel engaged in commercial fishing must take action to avoid any vessel that is not under command or restricted in their maneuverability. Finally, if one notices that a vessel is operating in water too shallow for its safe passage, one should take appropriate action to give it ample room to navigate. Always take early and appropriate action to avoid a collision regardless of the situation.
