In order for other vessels to see you and take the proper measures to avoid a collision while you are operating between sunset and sunrise, or in other periods of impaired visibility, such as fog or rain, you must use your navigation lights.

When at anchor, all vessels up to 50 meters in length must illuminate an all-around white light in a prominent location so that it may be seen easily. Keeping a thorough watch and displaying other lights – such as deck lights or cabin lights – when at anchor in a crowded location can help ensure that you are spotted.
What lights must a power driven vessel display when pushing another vessel?
Vessels Are Being Pressurized It is mandatory to have the following lights on your powerboat when towing another vessel or pushing another vessel ahead of you: two masthead lights in a vertical line, two sidelights, and one sternlight.
When operating a human-powered boat at night, keep in mind that you must have a functional electric torch, flashlight, or illuminated lantern that emits white light to comply with maritime regulations (this rule applies if the boat cannot be equipped with standard navigation lights.).
When other vessels notice you, the information provided by these lights is vital to their operations. Other boats in your vicinity make collision avoidance judgments based on the information they have at their disposal, which is why it is critical that the information your navigation lights are providing them is accurate.
Which lights must a vessel under sail exhibit from sunset to sunrise?
From sunset until sunrise, the operator of a sailboat sailing under sails at night must have the following lights on: sidelights (red – green); and sternlight (white) (white). If the length of the mast is less than 20 meters, the three lights may be integrated at or near the top of the mast to save space.
Which vessel must exhibit forward and after masthead lights when underway?
Vessel in motion with a power source: a masthead light ahead; a second masthead light abaft of and higher than the forward one; except that a vessel of less than 50 metres in length is not required to show a masthead light but may do so; There are sidelights and a sternlight.
What lights are required on a sailboat?
A red and green sidelight visible from a distance of at least two miles away—or, if the vehicle is shorter than 39.4 feet (12 meters) in length, from a distance of at least one mile away—on a dark and clear night are necessary. For vessels shorter than 39.4 feet in length, an all-around white light or a masthead light and sternlight may be used instead of the sternlight.
What lights must a 12m powerboat anchored at night display?
Power boats with a length of less than 39.4 feet (12 meters) are required to be equipped with the following set of navigation lights.
- Two kilometers away, you can see one white light that is all around you and can be seen from 360 degrees
- One pair of red and green sidelights that are visible at 112.5 degrees and from a distance of one mile.
What lights should be displayed when anchored at night?
(a) When a vessel is at anchor, it must display itself in the following locations: I an all-round white light or one ball in the forepart; (ii) an all-round white light or one ball at or near the stern and at a lower level than the light specified in subparagraph I an all-round white light in the aft part of the ship.
What must the operator of a powered vessel do in the presence of human-powered craft?
(a) When a vessel is at anchor, it should display itself in the following locations: (1) An all-round white light or one ball in the forepart; (2) an all-round white light or one ball at or near the stern and at a lower level than the light specified in subparagraph I (3) an all-round white light or one ball in the midsection.
What light should a sailboat use at night?
Generally speaking, a single white light that shines forward of the mast in a 225-degree circle is the most typical steaming light. Combining the stern light with the navigation light, a boat under power will now be flashing a 360-degree white light in addition to its red and green navigation lights. It is recommended that you employ this sequence of lights while MOTORING at night.
What is required on power driven vessels over 9m in length?
If you are operating a boat that is 9 meters or more in length, you are required to carry an anchor. The Small Vessel Regulations further require that an anchor be equipped with at least 15, 30, or 50m of cable, rope, or chain, in any combination, in addition to the minimum lengths specified above (the length depends on your boat).
This determines what type of navigation lights you must use and how they must be displayed: The length and width of your boat. Regardless of whether your boat is powered by electricity, human power, or sail power. Whether your boat is underway or at anchor, we have you covered.
On bridges that span navigable waters in the United States, navigational lights and other marine signals are required to be installed. The sole purpose of these signals is to prevent collisions between vessels and bridges.
Why should a vessel operator keep a proper lookout?
It is your obligation as a boat captain to ensure that you have an unobstructed view from the helm. Maintaining a watchful eye over your vessel and crew assures their safety. It entails modifying boat management techniques to account for factors such as darkness, fog, and boat traffic.
