    Anchoring is one of the great joys of sailing—dropping anchor in a quiet cove or an empty beach can be peaceful, scenic, and cost-effective compared to marinas. But it does require careful planning and awareness to do safely and comfortably. Here’s what to keep in mind:


    ⛵ 1. Safety First: Anchor Watch & Dragging

    Anchors can slip, so staying vigilant is key:

    Anchors can slip – this is the biggest worry.

    Anchor watch – If anchoring overnight, consider having one or two crew members monitor position regularly.

    GPS alarms – Modern alarms alert you if the boat moves beyond a set radius, but trust your eyes more than electronics.

    Preparedness – Always be ready for changing conditions.


    🌊 2. Check the Chart and Sea Bed

    Knowing the seabed and surroundings improves safety and environmental responsibility:

    Avoid hazards – Cables, pipelines, moorings, wrecks, or coral; anchoring on coral is harmful and often illegal.

    Sea bed type – Mud and sand generally hold better than rock.

    Anchor type – Choose wisely as different anchors perform better on different bottoms.


    📍 3. Scope and Depth

    The length of anchor rode matters for secure anchoring:

    Scope – Length of chain/rope relative to depth.

    Rules of thumb – Chain only: ~4x depth; Rope (warp): ~6x depth.

    Swing radius – More scope improves holding but increases swing; account for tidal changes!


    🛠 4. Allow for Swing Radius & Neighbours

    Consider your boat’s movement and nearby vessels:

    Swing radius – Equal to length of anchor rode out.

    Obstacles – Check for rocks or other boats within this radius.

    Stern anchor – Reduces swing; inform nearby boats to avoid conflicts.


    🏆 5. Consider the Weather & Shelter

    Weather can change quickly—plan anchoring locations carefully:

    Wind and tides – Avoid lee shores; understand local patterns.

    Comfort & safety – Overnight wind shifts may affect both.


    🏆 6. Be Considerate of Other Boats

    Maintain good etiquette for a safe and pleasant anchorage:

    Quiet arrivals/departures

    Leave room to swing

    Use correct lights or day shapes overnight

    Avoid crowding anchorages


    🌊 7. Swimming Safety at Anchor

    Ensure swimmers’ safety when anchored:

    Easy re-boarding – Make it simple for swimmers to get back on board.

    Tidal currents – Rig a line/fender from the stern for swimme
