Anchoring at night can be more challenging than daytime anchoring, requiring extra caution and preparation. This guide outlines essential steps to ensure a safe and secure night at anchor.

Planning and Preparation Before You Even Drop Anchor

1. Thorough Pre-Departure Checks:

• Weather forecast: Check the forecast meticulously, paying close attention to wind speed, direction, and predicted changes overnight. Unexpected shifts can be dangerous at anchor. A reliable weather app or dedicated weather service is crucial.
• Chart review: Carefully review your charts, noting potential hazards like shallows, rocks, wrecks, or other vessels. Identify backup anchoring locations in case your initial choice proves unsuitable.
• Anchor selection: Ensure your anchor is appropriate for the seabed type and expected conditions. A heavier anchor might be necessary in strong winds or holding on less-than-ideal substrates.
• Chain and rode: Verify you have sufficient rode (anchor chain or rope) – at least 5:1 scope (the ratio of rode to depth) is recommended, and more in windy conditions. Inspect your chain for damage or wear.
• Equipment check: Check your anchor windlass (if fitted), lights, VHF radio, and other essential safety equipment. Make sure everything is in working order.

2. Choosing Your Anchorage:

• Protected location: Opt for a sheltered bay or cove, minimizing exposure to wind and waves. Avoid areas with strong tidal currents or heavy vessel traffic.
• Sufficient depth and swing room: Ensure adequate depth for your vessel's draft plus sufficient swing room for the predicted wind and tidal changes. You need space to prevent colliding with other vessels.
• Clear seabed: Avoid areas with known obstructions or uneven seabed. Use your charts and depth sounder diligently.
• Consider other vessels: Select an anchorage where you can maintain a safe distance from other vessels. Check for any potential obstructions or hazards.

3. Approaching the Anchorage:

• Slow and steady: Approach your chosen anchorage slowly and cautiously, paying close attention to depth, currents, and your surroundings.
• Visual checks: Use binoculars to thoroughly inspect the area for potential hazards before dropping anchor.
• Soundings: Take frequent soundings to confirm your depth and avoid grounding.
• Prepare your anchor: Get your anchor ready before arriving at your planned location to minimize wasted time and potential error in high-stress situations.

Anchoring Procedures at Night

1. Setting the Anchor:

• Motor slowly: Continue to motor slowly while dropping anchor to ensure it settles correctly.
• Monitor rode: Watch your rode carefully to make sure it is paying out smoothly.
• Test the set: Once the anchor is set, try a light pull on the rode to check its holding power. A properly set anchor will hold firm.

2. Checking the Set:

• Use your GPS: Mark your position accurately on your GPS or chartplotter. This is vital for monitoring your position throughout the night.
• Monitor your position: Regularly check your position to ensure you aren't dragging. Look for changes in depth and surroundings, including any noticeable changes in GPS position.
• Visual cues: Look for visual cues, such as changes in the shoreline or other landmarks.

3. Nighttime Procedures:

• Navigation lights: Ensure all navigation lights are properly functioning.
• VHF radio watch: Maintain a constant watch on your VHF radio for weather broadcasts and other important information.
• Regular checks: Conduct regular checks of your anchor and position. How often depends on weather conditions, but at least once an hour is advisable. More frequent checks in adverse weather are essential.
• Alarm system: Consider using an anchor alarm system to alert you to any dragging. This technology provides peace of mind, and can be invaluable in unpredictable weather.
• Consider the tide: The tide is a major factor and must be considered when anchoring anywhere.

4. Troubleshooting:

• Dragging anchor: If you suspect your anchor is dragging, immediately increase your scope and try to reset it. If this fails, consider moving to a more suitable location or seek assistance.
• Emergency situations: In case of an emergency, contact the Coast Guard or other relevant authorities immediately.

Final Considerations

Anchoring at night presents unique challenges that require careful planning and attention to detail. By following these procedures, you can significantly increase your chances of a safe and enjoyable night at anchor. Remember, safety should always be your top priority. Preparation is key. Never underestimate the power of the sea, and always be prepared to react to changing conditions.
