Swansea Marina is accessed through the Marina Lock with access from the sea also through the Tawe Lock. Information on lock operating hours, access and procedures are available below.

Lock Operating Hours

Access to Tidal Locks

All access from the sea to the Marina is through the Tawe Barrage Lock during the published hours. During busy locking periods a queuing system will be in operation.

Vessels that do not make contact with the Lockmaster or disobey his/her instruction will not be given priority over other traffic. In the interest of every boat owner's safety, it is of the utmost importance that the Lockmaster's instructions are obeyed at all times.

Vessels leaving either lock must then transfer to the next lock's VHF channel on approach and use the appropriate procedure above.

Lock Availability
Marina & Swingbridge - call sign: 'Swansea Marina' CH. 80 Tawe Barrage Lock - call sign: 'Tawe Lock CH. 18
It is essential that all boat owners wishing to proceed through the locks or swingbridge operate a VHF radio.

Vessels must call 'Swansea Marina' on channel 80 before leaving their berth to request lock information and must remain listening on CH. 80 until passage through the bridge or lock is completed.

When you require use of the Tawe Barrage lock you must call 'Tawe Lock' to request information and remain listening on CH. 18 until the passage through the lock is completed. Do not proceed into the locks unless instruction has been given.

Important Notes - Lock Procedure

Normal procedure for locking out through the Tawe Barrage lock is for the lock to be taken down on the hour and return to the river on the half hour.

The first lock out of the day at the Tawe lock will be taken down at approximately 0710. The last Tawe lock in is half an hour before the close of business each day. Boat owners should be ready to leave their berth at approximately quarter to the hour to allow vessels sufficient time to enter the Tawe lock.

Any deviation from the above will be at the discretion of the duty Tawe Lockmaster who will pay due regard to the volume of traffic and any other prevailing conditions.

Any vessels not returning on the same day are required to inform the Lockmaster and Coastguard. Two holding buoys are situated downstream from the lock and may be used outside of locking hours. Great care is necessary at low water spring tides as there is a danger of drying out.

Milford Marina 51o42.25N 05o02.02W
Standard Port - Milford Haven (-0500 Dover)

Situated in an ideal location on the Milford Haven Waterway, Milford Marina provides more than just shelter along the Pembrokeshire coast. The locked marina offers fantastic sailing and water sports opportunities as well as plenty of things to do off the pontoon.

Access to Milford Marina is via the entrance lock. The lock gates are staffed 24/7 and with the installation of the Samson Gate, accessing the marina has never been easier.

Navigating to Milford Marina

For tides, refer to the Port of Milford Haven Tide Tables and consult Admiralty charts 1478, 2878, 3273, 3274, 3275, and Leisure Charts SC1478, SC2878, Imray 2600.11, C60.

For information on the Milford Haven Waterway, please refer to the Leisure User Guide. Milford Haven Port Control Centre can be contacted on VHF channel 12 (call sign 'Port Control').All vessels with a LOA of 20m and over must report to Port Control as required by the Port of Milford Haven General Directions.

During the summer months, to avoid disappointment we recommend contacting Marina Control (Tel: +44 1646 696312) 24 hours before your ETA to confirm availability.

Access to the dock basin is via the entrance lock. Lock times are published in advance on our website as well as displayed in Marina Control and on marina notice boards.

During the 'freeflow' period - which operates two hours before high water - up until high water, vessel movement is generally unrestricted.

Whilst every effort is made to adhere to the published lock times, mechanical failure, operational requirements, severe weather and/or planned maintenance may affect the programme.

Milford Docks Pier Head can be contacted on VHF channel 14 (call sign 'Pier Head') and to be allocated a marina berth contact Pier Head or Marina Control (call sign 'Marina Control') on channel 37.

Lock etiquette

All traffic using the lock is controlled by the Pier Head staff contacted via VHF Channel 14, call sign 'Pier Head'. (Tel: +44 1646 696310).

It is essential that vessels contact Pier Head before leaving the berth or entering the dock basin.

During all lock operations, vessels must moor alongside the pontoon/fenders provided, as directed by the duty lock keeper.

Moor as far forward on the pontoon as possible. If the pontoon is full, then it may be necessary to raft up, so fenders are recommended on both sides of your vessel.

When the lock cycle is completed, allow the vessels ahead and/or outside you to leave first.

All the vessels in the lock are to be secured with breast lines and springs.

Please observe the 'Dead Slow' speed at all times and remain vigilant when entering or leaving the lock.
