1. ENGLAND – East Coast – Measuring instruments. Buoyage. – Last year two Temporary Notices were about the installation of seabed equipment and special buoys in and around the Blackwater.

2. ENGLAND – East Coast – Depths. – Four increases in depth in the Deep Water Channel in the Black Deep and Sunk Inner area. Unlikely to hinder leisure craft.
3. BELGIUM – NM Block. – A new UKHO block for Oostende Harbour for Chart 1873.

1. SPORT & RECREATION ON THE THAMES – COVID-19 UPDATE – 5TH JANUARY 2021 – This notice supersedes and replaces Portwide Notice No.14 of 2020 – On Wednesday 6th January 2021 England enters a third period of national lockdown. The government has instructed that you must not leave or be outside of your home except for specific purposes. These purposes include exercise outdoors or visits to an outdoor public place. You should refer to the latest government guidelines prior to undertaking any sporting or recreational activity on the river and follow guidance from your NGB. It is for the individual to determine whether sport or recreation on the river is essential or justifiable under the current government guidelines.
Anyone considering recreational activity on the Thames must consider carefully the risks before going afloat. The Thames remains a challenging environment for recreational activity. Those taking to the water should be experienced, understand the Tideway Code and take all reasonable precautions to ensure their safety, including using the appropriate safety equipment. During this third period of national lockdown the Emergency Services remain available to assist in the case of an incident, but the significant reduction in other river traffic means that should someone come into difficulty, it is unlikely they will be seen and/or rescued by a passing vessel. It should also be noted that the PLA’s river patrol operations in the upper tidal Thames (Putney to Teddington Lock) are currently scaled down as resources are focused on the resilience of essential port operations.

8. Maldon Harbour Improvement Commissioners – COVID 19: NATIONAL LOCKDOWN – HARBOUR USE – (LEISURE VESSELS) – On Monday 4th January, the Prime Minister announced a new national lockdown to counter the steep rise in coronavirus (Covid-19) infections in England. Through the British Ports Association, we have now heard that Government have confirmed that “boating is allowed as exercise [in England]. This covers all sailing boats/yachts as long as persons abide by the gathering limits, social distance rules and stay local rules”. The use of kayaks, canoes and paddleboards etc, is also deemed as exercise. More information about what is and isn’t allowed is available on the government’s website. Further information is available on the RYA website and Sport England website. Obviously, the intention of the regulations is to reduce the spread of Coronavirus by ensuring that only necessary and permitted activities take place within the wider rules, including local travel. When making a decision on whether to go out on the water, please consider the risks and bear in mind that if you get into difficulty, you may be putting the lives of those come to your rescue at risk. We would be grateful if any enquiries can be made through email at
