When you're on the water after dark, are you sure your boat can be seen? Whether you're on a sailboat or motorized watercraft, your vessel needs navigation lights. Great Lakes Skipper's huge inventory includes marine bow lights, red and green bow lights, all-round boat stern lights, navigation side lights, boat transom lights, marine masthead lights, as well as spare bicolor lenses, plug-in light bases, spare sockets, bulbs, and boat light connectors from Perko, Aqua Signal, Attwood, Whitecap, Accon, and more top marine manufacturers.

Stern Light: This is a white light that is visible from behind a vessel.

Three Reds in a Row No Room Below: You have a duty to keep clear of a boat displaying three reds in a row. This refers to the runner rubbing on rocks or a vessel constrained by its draft. Is experiencing problems and should be avoided.

If two boats of similar size are approaching one another, then you want to alter your course to starboard. A handy way to remember this is by saying stay to the right and you’ll be alright.

[joechip]

If both the stern lights and side lights are seen brightly at the same time you still have a problem. A boat approaching won’t know whether they are overtaking or crossing and whether they should give-way or stand-on.

To alert other vessels of conditions that may be hazardous, there are requirements to display lights at night and shapes during the day.

Boating at night (or in reduced visibility) can present some special challenges. Not only is your depth perception lessened, but bright lights on the shore can also cast misleading reflections on the water and if you wear glasses, or worse yet bifocals, you simply don’t see as well at night as you do during the day.

Check your sidelights from dead ahead. You should see both red and green. However, by moving toward one side just 1-3º you should then see only one light. If you still see two lights, an approaching boat won’t be able to tell which direction you’re are going. more

Additionally, most of these flush-mounted sidelights are installed below the vessel’s rub rail. International Navigation Rules require that sidelights be installed above the uppermost continuous deck. Therefore, this configuration would not be in compliance with International Navigation Rules.

It is very important to be seen from a distance but also for an approaching boat to be able to determine your direction of travel.

There are a few fundamentals to help you figure out what that is you see on the horizon, which way it is going, and whether it is a danger to you. here

When you can see the color, you know which way the bow is pointing. If it's red, it's pointing more or less to the left and will travel in that direction. A green light shows it is heading more or less to your right. [links]

The good news is you need not measure these angles. Any properly installed USCG or COLREGS approved light which will cover the correct arcs. If you have to replace the original light from your boat, make sure it's with an approved replacement.

Be aware of red and green lights used in combination with other red, green and white lights. These may not be running lights and could have other significance. [links]

For all navigational purposes a sailboat under power is considered a power boat. This includes motor sailing - if the engine is on and providing propulsion you are on a power boat, even if the sails are up. This applies to navigation lighting, sound signals in fog and limited visibility, and rights of way.

is a navigation light used for towing. It's a yellow light placed at the forward end of a towing vessel or vessel being towed. more

If you are caught by the police not showing lights or showing improper lights, you will likely be fined. Worse yet, if the information your navigation lights are providing is incorrect and an accident occurs as a result of this, there could be serious repercussions.

The operator of a sailboat operating under sails at night shall, from sunset to sunrise, display: here

[Vasiliev]

At anchor, the operator of a pleasure craft shall display, from sunset to sunrise, in the fore part, an all-around white light. A powerboat anchored at night must display an all-around white light.
