Boating After Dark

Essential Tips for Boating After Dark

Boating after dark requires slower speeds, working navigation lights, careful route planning, reduced glare, and a constant lookout. Visibility is limited at night, which makes it harder to spot other boats, channel markers, floating debris, docks, jetties, shoals, and changes in weather or water conditions.

Before boating at night, check your equipment, dim bright displays, and make sure you have reliable communication tools onboard.

True, you probably have plenty of lighting, a good electronics package and enough local knowledge to ensure a safe passage.

So, what could possibly go wrong?

The answer is “plenty” if you don’t take the task seriously enough.

Miscalculation, poor judgement and bad luck compounded by restricted vision have a habit of leading to uncomfortable, dicey and even dangerous situations once the sun goes down. Indeed, boaters are more likely to miss-identify their destination or even home ports once the sun drops below the horizon. Others might fail to see another vessel, leading to collision. Some have struck jetties or docks at full speed, and even the most seasoned skippers and their crews are more likely to run aground under the cover of darkness.

Dislodged dock pilings, floating logs, low-profile sandbars and the like are harder to spot, and are a recipe for damage to your boat and possible injuries to you and your crew. Even gauging the height and force of waves becomes more complex in a nighttime scenario. If passengers are prone to motion sickness, rougher nighttime conditions can also make it harder to prevent sea sickness before discomfort sets in. That can lend itself to some surprising bumps in the dark if you fail to notice a rogue roller, large boat wake, strong rip, or confluence of currents.

As with most things on the water that old scout saying, “Be prepared,” serves well especially on the darkest of nights. If you expect to be cruising after sunset, prepare in advance before leaving the dock or launch ramp. 

Night Boating Safety Checklist

Before leaving the dock or continuing a trip after sunset, confirm that the boat, route, and crew are prepared for reduced visibility. Your night boating checklist should include:

• Red, green, and white navigation lights
• Anchor light
• Chartplotter, GPS, or navigation app
• Updated route and waypoints
• VHF radio or backup communication tool
• Flashlights or headlamps with red light mode
• Life jackets
• Visual distress signals
• Weather and tide conditions
• Fuel level and battery charge
• Local hazards, channels, markers, and no-wake zones

Check each item is in working order before departure rather than waiting until visibility is limited. Nighttime is not the time to discover a failed navigation light, low battery, or missing communication device.

What Do Boat Navigation Lights Mean at Night?

Navigation lights help other boaters understand a vessel’s position, orientation, and direction of travel. On most recreational boats underway, the red sidelight is on the port (left) side, while the green sidelight is on the starboard (right) side.. White lights may indicate the stern, masthead, or an all-round light, depending on the type of vessel and how it is operating. 

If you see both red and green sidelights, the vessel is generally approaching from ahead. If you see only red or only green, you are typically viewing one side of the boat. A white light by itself can have different meanings depending on the vessel and situation, including a stern or anchor light, so always interpret lights together with your surroundings, charts, radar when equipped, and a proper lookout.

Navigation light requirements vary by vessel size, type, and operating status. Make sure your boat displays the lights required for your situation and that every light is working before boating after dark.

Tips for Boating in the Dark

Review Navigation Charts Before Boating at Night

Start with a look at your navigation charts to ensure your route and way points are accurate and clearly defined.

Double-check that all navigation lights are functioning properly, and that you have working red-filtered flashlights on board (the filters reduce the flashlight glare). If you use them, ensure headlamp batteries are fully charged, too. Prior to departure  you’ll also want to clear the deck of the day’s debris, toys or fishing gear. Naturally, ensure you have the required number of properly-fitted jackets aboard.

Dim Onboard Lights That Affect Night Vision

Before getting underway be sure to dim or eliminate onboard lights that compete with your vision.

Dim cabin lights, accessory deck-lighting and electronics displays so you’ll have the clearest vision possible when peering out from the helm in any direction.

Keep a Proper Lookout at Night

Making way, stay alert and appoint a lookout.

Carefully follow the guidance provided by navigation devices, and keep your ears open for whistles, horns, gongs, voices and other boats. Realize, too, that seeing both red and green lights approaching is a boat headed straight in your direction. Take evasive action early to alleviate such threats. As with any other boating situation, a word on your VHF radio can help clear things up.

Slow Down When Boating After Dark

Lastly, pull back on the throttle when cruising after dark.

Caution should be your safe word at all times because it’s never worth risking family, friends, crew or your vessel to tie up a few minutes sooner.

In short, prepare ahead, slow down and stay well within the rules to ensure you get home safely.

FAQs

What lights are required when boating at night?

The exact navigation light configuration depends on the type, size, and operating status of the vessel. Recreational boaters should confirm that the required red and green sidelights and appropriate white stern, masthead, or all-round lights are working before getting underway. Boats at anchor may also need to display an all-round white anchor light. Check the navigation rules that apply to your vessel and boating area.

Why is boating at night more difficult?

Boating at night is more difficult because reduced visibility makes it harder to identify other vessels, channel markers, shorelines, floating debris, shallow water, and changing conditions. Fatigue and glare from on board lights can also reduce reaction time and make navigation more challenging.

Should you slow down when boating after dark?

Yes. Operating at a slower speed gives you more time to identify hazards, understand navigation lights, react to other vessels, and stop or change course if necessary. Your speed should always match the conditions, traffic, visibility, and surrounding hazards.

What should you do if your boat loses power at night?

If your boat loses power at night, make sure everyone is safe and wearing a life jacket, keep required navigation or anchor lights on, and immediately assess how the boat is drifting. Anchor if it is safe and appropriate to do so, share your GPS position, and use a VHF radio or phone to request help. If anyone is in immediate danger, contact the Coast Guard or local authorities.
