Advanced Mooring Systems (AMS) are one of the practical, innovative ways that we’re exploring to reduce seabed damage that can occur from the anchoring and mooring of recreational boats.

We’ve begun installing and trialling AMS within the Special Areas of Conservation that ReMEDIES is focusing on.

Traditional mooring

Figure A

Traditional swing moorings are most commonly used in UK waters, consisting of an anchor, chain (rode) and float. But they can result in abrasion to seagrass beds. As the tide rises and falls, differing amounts of chain will lie across the seabed, and will be pulled around in a circle as the tide and wind direction changes. Abrasion from the chain can remove leaves and shoots, as well as the rhizome system.

AMS are specially designed to reduce the interaction between the mooring and sensitive seabed habitats, including seagrass and maerl beds. These moorings are better for the environment and for boats.
