Study Notes
Three Major Responsibilities
- Practice good seamanship to ensure safe navigation and operation of the vessel.
- Keep a proper lookout to prevent collisions.
- Maintain a safe speed to allow for adequate stopping distance and reaction time.
Give-way Vessel
- Required to take early and substantial action to avoid other vessels.
- Should not cross in front of other vessels; changes in course or speed must be clearly visible.
Stand-on Vessel
- Must maintain its course and speed unless the give-way vessel is not taking appropriate action.
- Do not turn toward or cross in front of the give-way vessel.
Two Vessels Propelled
- Includes two power-driven vessels, two sailing vessels, or a mixture of both.
Two Vessels Approaching
- Meeting head-on: situation where vessels are nearly aligned.
- Crossing paths: vessels on a trajectory that poses collision risk.
- Overtaking: when a vessel approaches another from behind.
Definition of a Vessel
- Any watercraft capable of transportation on water, including seaplanes.
Power-driven Vessel
- Any vessel propelled by machinery, including those that utilize engines.
Sailing Vessel
- A vessel operated solely by sails without an activated engine.
Vessel Engaged in Fishing
- A vessel utilizing nets or equipment that limits maneuverability is considered engaged in fishing, excluding trolling activities.
Underway
- A vessel is considered underway when it is not anchored, tied to shore, or aground.
Risk of Collision (Power vs Power)
- Arises when approaching vessels maintain a constant collision course or when encountering large vessels.
Meeting Head On (Power vs Power)
- Neither vessel is designated as a stand-on; both should turn to starboard (right).
Paths That Cross (Power vs Power)
- The vessel on the operator's left (port) is the give-way vessel; the vessel on the right (starboard) is the stand-on vessel.
Overtaking
- The vessel performing the overtaking maneuver is the give-way vessel; the overtaken vessel remains the stand-on vessel.
Give-way Vessel
- Defined as the vessel needing to take action to avoid collision by stopping or altering course.
Stand-on Vessel
- Required to maintain its course unless it becomes evident that the give-way vessel is not acting appropriately.
Meeting Head On (Sail vs Power)
- The power-driven vessel is the give-way vessel; the sailing vessel remains the stand-on vessel.
Paths that Cross (Sail vs Power)
- The power-driven vessel is the give-way vessel, while the sailing vessel is the stand-on vessel.
Overtaking (Sail vs Power)
- The overtaking vessel, regardless of type, is the give-way vessel; the one being overtaken is the stand-on vessel.
Wind on Same Side
- The leeward vessel (downwind) is the stand-on vessel when sailing vessels approach each other with the wind on the same side.
Wind on Different Side
- The sailing vessel with wind on its starboard side is the stand-on vessel when approaching one another with the wind on different sides.
Leeward and Windward
- Leeward refers to the direction the wind is blowing towards; it pertains to vessels downwind of others.
- Windward indicates the direction from which the wind originates; it pertains to vessels upwind of others.
Meeting Head On (PWC vs PWC)
- Both vessels must turn to starboard as neither is the stand-on vessel.
Crossing Paths (PWC vs PWC)
- The vessel on the port side is the give-way vessel, while the starboard vessel is the stand-on vessel.
Overtaking (PWC vs PWC)
- The overtaking vessel is the give-way vessel, while the one being overtaken is the stand-on vessel.
Operator Of Power Give-Way Rules
- Certain vessels not under command or restricted in maneuverability must give way; this includes those engaged in commercial fishing.
Operator of Sailboat Give-Way Rules
- Similar rules apply, where vessels not under command, restricted, or engaged in commercial fishing must yield.
Engaged in Commercial Fishing
- Defined by use of equipment that restricts maneuverability, excluding trolling.
Restricted Visibility
- Weather conditions that impair visibility, such as fog, mist, rain, or snow.
Navigation Lights
- Sidelights are red (port) and green (starboard) visible from side and head-on.
- Sternlight is a white light visible from behind.
- Masthead light shines forward and is required on power-driven vessels.
- All-round white light can replace masthead and sternlights on smaller vessels.
Light Signals
- Different light combinations indicate vessel status and intent, such as overtaking, anchored, or stand-on positions.
- Short blasts signal passing intentions; prolonged blasts are used as warnings or sailing vessel signals.
General Safety Signals
- A series of rapid blasts indicate danger or confusion regarding intentions, guiding operators in navigation decisions.
