stand-on vesselWhen one of two vessels is to keep out of the way (give-way vessel), the other, the stand-on vessel, must maintain course and speed. The stand-on vessel must take avoiding action when it becomes apparent that the vessel required to give way is not taking appropriate action.
Sound Signals & Rules For Overtaking & Crossing The vessel being overtaken is the Stand-On Vessel. The Stand-On Vessel maintains course and speed. The Give-Way Vessel must take early and substantial action to avoid the Stand-On Vessel. In the diagram above Vessel 1 is the overtaking or, Give-Way Vessel.
Give-way vesselGive-way vessel: The vessel that is required to take early and substantial action to keep well away from other vessels by stopping, slowing down, or changing course.
D. on the inland waters of the U.S. In which situation do the Rules require both vessels to change course? If a sailing vessel with the wind on the port side sees a sailing vessel to windward and cannot tell whether the other vessel has the wind on the port or starboard side.
In accordance with Rule 16 (Action by give-way vessel), every vessel (vessel B) which is directed to keep out of the way of another vessel (vessel C) shall, so far as possible, take early and substantial action to keep well clear.
Meaning: The action that the stand on vessel finally takes to avoid the situation depends on what is the nature of the action of the give-way vessel, if the action is insufficient to clear the close quarter situation than the stand on vessel has to take action which will get the two ships safely away from each other.
When two power-driven vessels are in crossing situation on a collision course, give way to the vessel to starboard (right). The give way vessel must take early and obvious action to avoid a collision by either stopping or altering course to starboard.
When two vessels are operating in the same general area, who is responsible for avoiding collision? The operators of both vessels.
the give-way vesselVessel A is overtaking and is the give-way vessel. Vessel B is the stand-on vessel. As the give-way vessel, A must take EARLY and SUBSTANTIAL action to keep clear of the stand-on vessel B.
ColRegs Rule 14 governs meeting or head-on situations and states that “when two power-driven vessels are meeting on reciprocal or nearly reciprocal courses so as to involve risk of collision, each shall alter her course to starboard so that each shall pass on the port side of the other.”
Rule 17(a)(i): when you are the 'stand-on vessel', you must keep your course and speed. You must not do anything unexpected. Rule 17(a)(ii): 'as soon as it becomes apparent' that the give-way vessel is not taking appropriate action, then you may take your own action to avoid a collision.
When, from any cause, the vessel required to keep her course and speed finds herself so close that collision cannot be avoided by the action of the give-way vessel alone, she shall take such action as will best aid to avoid collision.
Any vessel fishing with nets, lines, trawls, or other fishing equipment that restricts maneuverability; however, does not include a vessel fishing with trolling lines or other fishing equipment that do not restrict maneuverability
The vessel that is overtaking another vessel is the give-way vessel. The vessel being overtaken is the stand-on vessel.
The vessel that must maintain its course and speed unless it becomes apparent that the give-way vessel is not taking appropriate action. If you must take action, do not turn toward the give-way vessel or cross in front of it.
Any condition in which visibility is restricted by fog, mist, falling snow, heavy rainstorms, sandstorms or any other similar causes
When two sailing vessels are approaching one another with the wind on the same side, the leeward sailing vessel is the stand-on vessel.
neither vessel is the stand-on vessel, both move to the right (starboard) (unless sailing vessel-always stand-on)
