UKHO Permanent/Temporary/Preliminary
1. ENGLAND - East Coast - Piles. - Three new yellow special buoys marking artificial nesting structures, one placed off shore Minsmere Haven and two off Kirkley (south of Lowestoft). Mariners are advised to navigate with caution and maintain a safe distance of at least 500m from construction vessels in the area. Presumably the Lowestoft pair are still under construction.
2. NETHERLANDS - NM Blocks. Buoyage. - This notice comprises three UKHO block for two charts and details of changes for buoy positions and characteristics for a third chart, all in relation to the approaches to Roompotsluis. Most of the changes relating to the third chart are slight movement and re-designation but also the insertion of a new east cardinal buoy which acts (effectively) as a port hand buoy for the Roompot channel and as a starboard hand buoy for the Oude Roompot channel. Whilst the UKHO blocks show the changes I have added an annotated ‘chartlet’ showing the changes (courtesy of Imray). Only the annotated image is shown but all four images can be download via the usual button. Notices to Mariners
