It might be my plotting skills, but trying to plot the grid reference given for Tetney Monobuoy (52º 32'.36N 000º 06'.75E) is very firmly on land near the Fenland town of March. I believe the grid reference should be 53º 32'.36 N 000º 06'.78 E

Ed note: Thanks, typo corrected 52º should be 53º

Tetney monobouy has a 500 m exclusion zone around it this is monitored 24 7 by a support vessel and VTS who will contact you on C14

I reviewed these notes in June 2022. I've added some notes on the Donna Nook firing range. There's a new Aldi nearby and I've had a look at the train times from the Docks to the centre.

I reviewed these notes in May 2021 and the AIS screen was full when I did it! There haven't been much in the way of changes although the marina price has gone up 10p a metre. I've also rewritten the text a bit to emphasize the fact that yachts inbound for the Marina use the smaller lock gates to the East of the tall tower.

The cost of entering Fish Dock outside of free flow times is now £20

We have altered the Approach notes in regard to crossing the Humber TSS from North to South with reference to the ABP Humber preferred routes; we have kept the option of crossing inside Spurn Head.

These notes were updated by Don in March 2015. They are not changing their visitors fees for 2015. I've changed the call sign for the VHF as suggested by "mudlark"

The call sign for the lock is actually Fish Dock Island & you might be ignored if you use Fish Docks as in script.

These notes were reviewed by Don T on the 9th April 2013. The prices for visiting boats for the summer of 2013 have been held to the 2011 rates. I have changed the tidal reference to Immingham as that is the local primary port and a link to those tide tables has been included in the "Tides" section

11-14/7 – Grimsby – Grimsby used to be the biggest fishing port in the world, however as the industry declined so has the port and the surrounding area. The Grimsby yacht club has a nice marina an hour down the Humber, on approach there is LOTS of shipping and it is wise to radio the pilot and see what the traffic is doing. The surrounding area has a large Asda for restocking but the town is fairly derelict and run down. The people who run the marina are very nice and there’s a great time to be had in the clubhouse.
