Recreational sailors navigating the Thames Estuary should take note of key guidelines from the Port of London Authority (PLA) regarding the use of the Black Deep Channel. A recent statement from the Deputy Harbour Master clarifies the rules and considerations for pleasure vessels in this vital area, which is primarily used by large commercial ships due to its depth and strategic importance.
Black Deep Regulations: What Sailors Need to Know
The PLA General Directions for Navigation include GD 17.5, which prohibits vessels with a draught of less than 6.0m from using the Black Deep Channel without explicit permission from London Vessel Traffic Services (VTS). This regulation, unchanged for several years, aims to separate smaller vessels from the ultra-large container ships and other commercial vessels that rely on this route.
By reducing traffic density, the regulation ensures greater safety in this narrow channel, particularly where one-way working is enforced during the transit of ultra-large ships.
Key points for recreational sailors include:
•Permission Required: Smaller vessels, including pleasure boats, must seek permission from London VTS before entering the Black Deep.
•Crossing the Channel: Permission is likely to be granted for east-west crossings or for journeys to/from Foulger’s Gat or Fisherman’s Gat. However, onward navigation through the Knock John Channel is unlikely to be approved.
•Advance Communication: If VHF communication issues are anticipated, sailors are encouraged to contact London VTS by telephone in advance.
•Possible Restrictions: Permission may be denied during restricted visibility, heavy weather, or other special circumstances, such as project towage or incident response.
Recreational Sailors Urged to Plan Ahead
The PLA emphasizes the importance of preparation for all vessel masters, including recreational sailors, navigating within its jurisdiction. While not all regulations apply to smaller pleasure vessels, understanding those that do is critical. The International Collision Regulations (Colregs) must also be adhered to, particularly Rules 9 and 18, which prioritize vessels constrained by their draught.
Sailors are reminded that failing to research and comply with PLA regulations could lead to serious consequences in the event of an incident.
Practical Advice for Thames Navigation
The Deputy Harbour Master advises sailors to consider alternative routes where possible, avoiding the Black Deep and other channels primarily used by large commercial vessels. For those who must navigate the Black Deep:
•Contact London VTS in advance via telephone (01474 560311) or VHF (Channel 69 east of Sea Reach 4 or Channel 68 west of SR4).
•Anticipate the possibility of waiting for large vessel traffic to pass before permission is granted.
•Ensure familiarity with PLA regulations, which can be accessed online or by contacting the Harbour Master team at recreation@pla.co.uk.
Maintaining Safety and Compliance
The PLA’s goal is to ensure safe and orderly navigation for all users of the Thames Estuary. By adhering to these guidelines, recreational sailors can enjoy their passage while minimizing risks in one of the UK’s busiest maritime areas.
