Most of the local Maerl Beds around Falmouth are only accessible by boat. There are several beds around, including in the Carrick Roads, Percuil River, Helford River and an area off Pendennis. Although Maerl can be found across a lot of Falmouth bay, it is mostly a light smattering.

The Maerl beds are mainly shallow, between 5m to 9m. All lie in tidal areas, so need to be dived around slack water.
