The use of a deadweight for anchoring is common in restricted areas, municipal ports and protected marine areas. Although this maneuver is often thought of as harmless, there are a number of factors that can complicate it. Here are the eight essentials you need to know.
1- Preparing for the upwind approach: a basic rule
Arriving into the wind stabilizes the boat and makes it easier to grab the trunk.
This is the classic method, particularly recommended for maneuvers with inexperienced family crews. With the engine idling, the boat moves slowly towards the buoy.

2 - Reversing: a technique for more experienced boaters
Arriving upwind allows the transom to be presented at the buoy, within easy reach of the helmsman, who still has a good view of the boat for maneuvering. This method, often recommended by experienced sailors, requires a good assessment of the boat's headway and precise coordination between helm and gaff. It may be easier to catch the buoy from the cockpit on some boats. But it requires a boat that remains maneuverable in reverse.
3 - Managing the current: a tricky maneuver in a dynamic zone
Wind and current dictate a dual reading of the water. In areas such as the Gulf of Morbihan or certain Breton rias, the current can dominate the wind. You need to observe the behavior of other boats already moored on their chests, identify the combined dunnage, and adjust your approach with great flexibility, engine idling.

4 - Mooring on the buoy: attach directly to the chain
The ring on the top of the buoy should only be used as an aid for gripping the trunk. It allows you to capture the buoy with the boat hook and pass a first temporary mooring line. For a more secure mooring, you need to lift the buoy and attach it directly to the chain underneath.
5 - Passing a double mooring line: for manoeuvring comfort
Using a double mooring line reduces stress on the cleats and facilitates departure. This set-up makes it possible to pick up the trunk quickly and release it efficiently on departure. But if you're going to keep this mooring for more than an afternoon, it's advisable to tie a bowline knot on the deadweight.

6 - Avoiding errors on the ring: for safe mooring
Direct friction quickly weakens the hawser on the deadweight. Making a dead turn in the ring before hitting the cleat limits the amount of chafing. This happens quickly in windy or fast-moving areas.
7 - Protecting mooring lines: a question of longevity
Protective hoses prevent premature hawser wear. The addition of a piece of hose, held in place by toggles, reduces friction on the buoy and in the fairleads on the planking. Simple, reliable, inexpensive and suitable for long-term installation.

8 - Anticipating the release of the deadweight: for a successful start
Knowing where the boat is drifting before casting off is essential. Observing the boat's behavior, estimating the direction of drift, and keeping the engine engaged at idle allow a safe release, without the risk of drifting towards other units or wrapping the mooring line in the propeller.
