There have been a number of questions about boating lights here recently, so I'm assuming this is another.
The answer to this one is complicated, and depends on:
1. If the boat is a sailboat or a powerboat (sailboats which also have motors are considered powerboats if the motor is in use).
2. If the boat is in motion or at anchor.
3. The size of the boat.
You should really be a lot more specific with the question if you want a definitive answer; specifically you should say whether it's a sailboat or a powerboat, if it's under sail/power or at anchor, and how long the keel is.
What else can I help you with?
A powerboat less than 39.4 feet long is anchored at night From which direction must a white light be visible?
A powerboat less than 39.4 feet long is anchored at night white light must be visible from all directions.
Where must the white light be visible for a power boat 395?
A white light on a powerboat (that obviously doesn't have a mast) must be displayed so as to be visible from 360 degrees.
Which direction must the white masthead light be visible?
Rule 21 It must show an unbroken light over an arc of the horizon of 225 degrees and so fixed as to show the light from right ahead to 22.5 degrees abaft of the beam.
When a powerboat is operating at night from which directions must the white masthead light be visible?
When a powerboat is operating at night, the white masthead light must be visible from both the front (fore) and the sides of the vessel. It should be mounted at least 1 meter above the sidelights and visible from an angle of 225 degrees. This ensures that other vessels can see the powerboat's position and direction of travel, enhancing safety on the water.
A vehicle must have a white light that makes the license plate visible from?
25 ft.
What color light must a kayak use at night?
At night, a kayak must use a white light to be visible to other vessels. This can be a 360-degree white light mounted at a height of at least 3 feet above the waterline. Additionally, if the kayak is in motion, it should display a red light on the port (left) side and a green light on the starboard (right) side to indicate its direction. These lights help ensure safety and visibility on the water.
What lights are all vessels required to display when moored or anchored outside a designated mooring a area between sunset and sunrise?
This white-colored light that must be visible from all angles is called an anchor light. It is usually situated atop the mast.
What color light must be displayed by a commercial vessel that is towing at night?
A white light is the color of light that must be displayed on a vessel towing at night, I t must be displayed at 8.2 feet higher than the colored sidelights. It should have an all round white light visible for 2 miles.
What color must be added to a green light to become a white light?
White light is the full spectrum of visible light. So in order to get true white light you need to add violet, blue, yellow, orange, and red.
Will you get white light when you mix yellow light and blue light?
To get white light, you must mix all the colors (red, orange, yellow, green, blue, indigo, and violet)
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.
In For a substance to appear white what must happen to all wavelengths of light?
For a substance to appear white, all wavelengths of light must be reflected equally and simultaneously. This results in a balanced mixture of all visible colors being reflected off the surface.
