Red – vessels must not proceed. Vessels inbound to the lock should heave to or give way to outward bound vessels
Green – vessels may enter the lock.
Green/white/green – caution. Vessels may proceed only when specific instructions to do so have been received.
Obey the directions of the lock keeper, approach the locks with fenders rigged on both sides of your vessel and mooring lines ready. Tie up as far forward into the lock as possible, or alongside other vessels. Always move as far forward in the lock as possible and when secure, switch off your engines and radar. Help others coming alongside after you.
We recommend springs are used where possible, although even when the locks are sluicing there is very little water movement in the area where the boats are moored. A lock keeper will greet you onboard, take basic details of your vessel and allocate a suitable berth via a computerised management system.Once you are secured in your berth, please call at the Marina Reception to register.
The basins behind the lock need occasional ‘top-ups’ which we do during high tide. At this time we operate a single lock. Regular broadcasts on VHF Channel 17 announce the status of the locks and timings of any closures
Do not use lock ladders unless in an emergency
