A power-driven vessel may show an all-round white light instead of a masthead light when at anchor. Additionally, when under way and restricted in her ability to maneuver, she may display a special light configuration, including a white light at the top and red and green sidelights. This ensures other vessels can easily identify her status and intentions.

What may a power driven vessel of less than 12 meters in length show instead of the masthead light and sternlight?
A power-driven vessel of less than 12 meters in length may show an all-round white light in lieu of the masthead light and sternlight. This all-round white light must be visible from all directions and is typically mounted at a height that ensures visibility. Additionally, the vessel may also display sidelights if it is engaged in activities requiring them.
What is the colour of the masthead light?
The masthead light is typically white in color. It is displayed at the top of a vessel to indicate the presence of another vessel at night.
What may a power drivin vess less than 12 meters in length carry instead of the masthead light and sternlight?
A power-driven vessel less than 12 meters in length may carry an all-round white light instead of the standard masthead light and sternlight. This all-round white light must be visible from all directions and should be positioned at or near the highest point of the vessel to ensure visibility. Additionally, the vessel should display side lights when operating between sunset and sunrise.
On power-driven vessals what are the navigation lights?
Generally they are masthead light, port and starboard steaming light and stern light. Others may be displayed depending on the length of the vessel and what duties it is carrying out.
What are the characteristics of nav lights on a power driven vessel?
The characteristics of navigation lights on a power driven vessel includes sidelights, sternlight, masthead light, and all-round white lights. Navigation lights must be displayed from sunset until sunrise as well as anytime visibility is restricted.
What is a masthead light on a vessel?
Rules of the Road Lights & Shapes, Rule 21-International Definitions (a) "Masthead light" means a white light placed over the fore and aft centerline of the vessel showing an unbroken light over an arc of the horizon of 225 degrees and so fixed as to show the light from the right ahead to 22.5 degrees abaft the beam on either side of the vessel.
In addition to an all round white light what light must power-driven vessels less than 65.6 feet exhibit when underway between sunset and sunrise?
Rules of the RoadInternational/InlandLights & shapesRule 23-Power-driven vessels underway(a) A power-driven vessel underway shall exhibit:(i) a Masthead light forward;(ii) a second masthead light abaft of and higher than the forward one; except that a vessel of less than 50 meters in length shall not be obliged to exhibit such a light but may do so;(iii) sidelights; and(iv) a stern light*note on side lights. Red is port side (left) and green is starboard side (right)
What is the Arc of visibility of masthead light?
The arc of visibility for a masthead light is 225 degrees. This means that the light must be visible from dead ahead to 22.5 degrees abaft the beam on either side of the vessel.
What is a masthead light?
A masthead light is a white light located at the highest point of a vessel, typically on the mast or superstructure. It helps other vessels identify the boat's presence, direction of travel, and size when navigating in low visibility conditions. The masthead light is required by maritime regulations, especially at night or in restricted visibility.
A powerboat is operating at night from which directions must the white masthead light be visible?
Rule 21 of the Navigational Rules of the Road. (a) "Masthead light" Means a white light placed over the fore and aft center-line of the vessel showing an unbroken light over an arc of the horizon of 225 degrees and so fixed to show the light from right ahead to 22.5 degrees abaft of the beam on either side of the vessel, except that on a vessel of less than 12 meters (39'4") in length the masthead light shall be placed as nearly as practical to the fore and aft center-line of the vessel.
In addition to an all-round white light what lights must power-driven vessels less than 65.6 feet long exhibit when underway between sunset and sunrise?
Rules of the RoadInternational/InlandLights & shapesRule 23-Power-driven vessels underway(a) A power-driven vessel underway shall exhibit:(i) a Masthead light forward;(ii) a second masthead light abaft of and higher than the forward one; except that a vessel of less than 50 meters in length shall not be obliged to exhibit such a light but may do so;(iii) sidelights; and(iv) a stern light*note on side lights. Red is port side (left) and green is starboard side (right)
What direction should the masthead light be visible from while boating at night?
The masthead light on a vessel should be visible from the front and sides, specifically from 22.5 degrees on either side of the bow, extending to the stern. This light is white and must be displayed from sunset to sunrise, ensuring that other vessels can see your boat's heading and position. Proper visibility of the masthead light is crucial for safe navigation and collision avoidance at night.
