Smallgains Marina sits on Smallgains Creek off Canvey Island, Essex, providing access to the Thames Estuary via the Ray channel.

The marina offers jetty moorings on both the north and south banks of the creek, along with hardstanding storage options including covered dome shed space and concrete hardstanding.

Facilities include crane and forklift hire, jet washing, hull scrubbing, and water. Lift-out and re-launch services are available for both monohulls and catamarans. The creek is tidal, so skippers should plan arrival and departure times accordingly.
