Bristol - Docking
Any kind of approach to Bristol needs good timing and planning. The tides in the Severn Estuary are fierce with ranges of up to 13m. These will have to be negotiated before you get anywhere near the River Avon. Streams can reach up to 5 knots at springs and 3 Knots at neaps.
The marina at Portishead makes timing your arrival at the entrance to the Avon, a relatively simple matter, however with such a tidal range the correct timing of harbour approaches is crucial. The cross-tide at Avonmouth can be 5 knots.
Yachts bound for Bristol must keep a listening watch on VHF channel 12 at all times. When passing Black Rock (just under a mile before the first lock) call City Docks Radio on VHF channel 14 (low power) to make contact. A further call should be made to City Docks Radio for final instructions on entering the lock when passing Hotwells Pontoons.
It is 6 miles up the Avon to the city docks, and yachts must aim to be at the river entrance 2 hours before HW Avonmouth. After passing under Brunel’s suspension bridge, the Cumberland Basin lock is not far, just around the next bend. Once through into the Floating Harbour, there is a wide number of options for berthing.
The lock into the Floating Harbour only opens from a couple of hours before HW to about 15 minutes before HW. Visiting vessels, therefore, need to arrive at the lock entrance within this window of time. If you miss the lock by arriving too late you will have no alternative other than to exit the River Avon completely, as there is nowhere to stop safely while awaiting the next tide.
Cumberland Basin Lock
Dock Master
Tel:+44 (0)117 927 3633
VHF Channel 14 “City Docks Radio” (use low power)
The lock opens at HW -2½, HW -1½ and HW -¼ If the last lock-in is missed, call VHF channel 12 for advice. The river dries, but the mud at the waiting pontoons is soft. The lockmaster is on duty from 3 hours before HW until about 45 minutes after. The bridges are not opened if the level in the river is above the level in the Floating Harbour. Nor are they opened between 08:00-09:00 and 17:00-18:00 (Mon-Fri).
