Week 18

UKHO Permanent/Preliminary/Temporary

1. ENGLAND – East Coast – Depths. – One reduction of depth in northern part of Caister Road (north of Caister).
2. ENGLAND – East Coast – Depths. – One quite significant reduction of depth right in the middle of the gutway at the entrance of the lock of King George V Entrance Lock, River Thames.
3. ENGLAND – East Coast – Depths. – One reduction of depth well off shore (2.8nm) east of the South Cross Sand off Great Yarmouth. Not likely to hinder leisure craft.
4. ENGLAND – East Coast – Depths. – One reduction of depth at the southern entrance of the North Edinburgh Channel. I noticed there was a survey a couple of months back so only one reduction of depth is good news.
5. ENGLAND – East Coast – Depths. – Two reductions of depth in the River Thames: one right off the Tilbury Cruise Terminal, the second off the Esso Jetties off Pufleet. Neither likely to hinder leisure craft and not where ought to be!
6. BELGIUM – Buoy. – New north cardinal buoy temporarily installed in the middle of the Wenduine channel leading to Blankenberge.
7. BELGIUM – Depths. – Some serious depth problems right at the entrance to Nieuwpoort. Normally a 3m channel is maintained but is reported as less than 1m. I am sure we can expect some early dredging.
8. BELGIUM – Marine Reserves. Restricted areas. Mine laying practice area. – 5 different boundary changes:
A new marine reserve on the Vlakte Van De Raan.
An update of the boundary of the Marine Reserve extending just east of Oostende harbour northerly – very small change.
A restricted area prohibiting anchoring and fishing near Middelkerke; a small area unmarked visually.
A revision of the boundaries for the min-laying practice area off Wenduine.
A prohibited area just east of Zeebrugge.
Five separate images.
