All Marina users are reminded that we share the entrance to the river with the fairway for commercial shipping entering and leaving the port of Swansea.
It is very important that all boat owners obey the rules laid down by the authorities and give way to commercial shipping at all times.
Entering and Leaving the Port
All pleasure craft using the port must observe the rules governing the “Prevention of Collisions at Sea”, particularly when navigating within the dredged channel North of the SWIGG buoy (South West Inner Green Grounds) to the harbour entrance.
You are advised to approach the harbour entrance in the waters to the west of the dredged channel (where practicable).
Large vessels entering or leaving the harbour must be given a wide berth at all times.
All pleasure craft must be under power when in the vicinity of the harbour and should clear waters used by commercial shipping as soon as possible.
To seaward, vessels approaching the harbour will see 9 signal lights displayed in 3 columns of 3 lights. The centre light of the westerly column controls pleasure craft.
When this light is red craft must not enter the river and should hold SW of the western breakwater. If in doubt call Swansea Docks VHF Channel 14, or Tawe Lock Channel 18
When the entry lights of the Tawe lock come into view, vessels should make radio contact for locking instructions and information from the duty lockmaster on VHF Channel 18. Call sign “Tawe Lock”.
