The harbour entrance lies between two piers. The main channel is indicated by red transit lights at night and diamond shapes by day on the South Quay bearing 239° 38'. The leading lights at the approaches to Weymouth Harbour are high intensity units with a range of 7.5 miles.
Traffic signals are displayed in a vertical line from a mast on the South Pier. When passage in or out of the harbour is restricted the signals will be operational and the lights must be observed.
Weymouth harbour is a small but very busy place with many thousands of transits each year. The speed restriction is that operators of craft proceed at a speed whereby their "wash does not cause annoyance to other harbour users". If in doubt, look behind you, you may be surprised at the effect your wash is having on moored craft left bobbing and dipping in your wake.
A fast cat ferry service to the Channel Islands runs daily usually sailing early and returning late. Movements of all ferries are indicated by the traffic lights on the south pier.
Small rowing ferries operate across the harbour we ask that you give way to them, giving them a wide berth at slow speed.
