1. Trinity House - GENERAL LIGHTHOUSE AUTHORITIES 2020 AIDS TO NAVIGATION REVIEW - The General Lighthouse Authorities (GLAs) will be undertaking a review of Aids to Navigation provision around the coasts of Great Britain and Ireland during 2019. The Review will be published in 2020 and will inform the GLAs’ work plans for the following five year period. The GLAs currently provide a comprehensive network of Aids to Navigation for general navigation i.e. navigation outside harbour authority areas, commensurate with the degree of risk and volume of traffic. This usually excludes close inshore areas where navigation is not encouraged.

Marine users of Aids to Navigation are invited to contribute to the review by commenting on:
- The usefulness and usability of existing aids to navigation provided by the GLAs
- Any proposed requirement for the provision of new aids to navigation

Comments regarding Aids to Navigation provision around England, Wales and the Channel Islands should be addressed to navigation.directorate@thls.org before 15th March, 2019.

2. LOWESTOFT APPROACHES – POSSIBLE SHOALING EAST OF HARBOUR ENTRANCE - Mariners and Port Users are advised of an area of suspected shoaling approx. 350 metres East of Lowestoft Harbour entrance, centred on approx. position 52˚ 28.260’N, 001˚ 45.700’E. This shoaling has yet to be confirmed, but may have resulted in depth reduction of between 0.5m and 1.0m. This area is shown on the chart extract on the above page in the Temporary list. (A depth reduction of 1m would give 3.1 CD)

3. River Great Ouse – A47 Bridge Inspections - Mariners are advised that inspections and investigations are to be carried out on the A47 Bridge that crosses the River Great Ouse at King’s Lynn on the following dates and times.
 Phase 1, 31-01-19, 1 overnight shift 2000hrs to 0600hrs.  Phase 2, W/C 25-02-19, 3 weeks, overnight shifts, 2000hrs to 0600hrs, Mon to Fri only.
An under bridge inspection platform will be deployed for these operations which will be fully illuminated and can be manoeuvred to allow passage if required. A dedicated lookout will be on the platform to maintain a safe watch for any marine traffic. Mariners are requested to navigate with caution in the vicinity when these operations are underway.

No Port of Wells update, no Havengore Bridge update (broken), no Foulger's Gat issues.

That's it.
