On passage from Boston to Walton on the Naze, at 0030hrs, came within 20 metres of an unlit red bouy at about 52deg.53'N 01deg.27'E. This is not marked on my C28 Imray chart and I cannot find it mentioned in any updates. Coastguard says it has been there for ever and marks the outfall at Mundesley. Does anyone have an Admiralty chart for Norfolk, or one of the electronic charts and if so is the bouy marked. I would like to be sure of my facts before talking to Imray. Thanks. Paul
 
Thanks for the replies. That C-Map online chart is very good and I have bookmarked it. The bouy is definately not marked on C28 Imray chart. The boat owner is now ringing Imray to see what they have to say. I will let you know the outcome. Paul
PS The bouy is definately not lit and it is a big one!
 
You cant always trust new charts! I also had an Imray (new) with a lighthouse on the wrong headland! they said sorry! and sent me a new chart....but I could have quite easily ended up on the rocks had I just used the lights to enter the harbour.

I think they said it was just human error in transposing data.
 
You can't expect an Imray chart to have every buoy and detail on it, the scale is not appropriate. I expect that's what they'll say to you if you phone.
Just checking my local chart out of interest, the buoys at the entrance to Ardrossan are not marked on Imray, but that does not surprise me - to put all the detail in would clutter the chart.
I think if you are driving about the coast in the middle of the night you should be carrying the relevant admiralty charts - IMHO Imrays are for planning and not much else (although some of the little chartlets are good).
It seems a bit odd to be phoning CG, Imray et al when you appear to have been ill-eqipped to navigate safely in the first place.
Anyway - you missed it!

If my (solent) Imray charts can display all the racing marks in addition to the Nav marks then I'd be supprised too if I discovered a long established mark not shown on a new chart.
What scale was the chart that didn't show the mark? There's hardly that many marks round there that they couldn't fit it on .. do the chart makers have specific rules on which marks they show or not depending on the scale?
 
It's certainly on C-map (2002 charts)at pos 52deg52.723N 1deg26.653E.

Described as "Beacon Port hand Colour Red, Pipeline Mundesley"

Its on the 2m contour more or less.

Get yourself some decent electronic cartography like C-map.
There is no substitute.

Well, I would not use a 1:125,000 chart to navigate in less than 5m of charted depth, less than 3 cables from the beach, at midnight. That's only my view, of course, but what do I know? Your Solent chart is, I think, 1:35,000 so can include a lot more detail.
 
Imray admit that CAN BOUY at 52deg53'24N and 001deg27'36E was not shown on the May 2002 edition of C28 but it is shown on the 2004 edition. As soon as a new edition is issued they delete the "internet" corrections to the previous chart so I am unsure as to whether the bouy has been there "for ever" as the Coastguard said or whether there was an update we have not seen. On the night the Coastguard said he would notify Trinity House of the unlit bouy and we have since been told by TH that they got the call and non of their bouys were missing. I cannot understand why the Coastguard did not inform us that the bouy was in the correct position.

The C-Map link mentioned by AngusMcDoon shows the bouy and the beacon. We were in 10 metres of water 1 mile offshore.

Steverow. Does your chart show the Bouy? You are talking about the beacon in shallow water.

Superatrath. Well equipped (note the English spelling!) boat, 4 yachtmasters/each yacht owners (over 100 years experience between them), working a watch system with 3 on watch at that time because there were loads of fishing boats about, a passage we have done 10 times in the last 5 years. Maybe you have not experienced night passages, but in any case you do not know enough facts to criticise how well prepare, or competant, we were. IMHO.

Conclusion-: Either the bouy has allways been there and the Imray chart was not correct, or somehow we missed a chart update. Thanks for the interest shown. Paul
 
Even Admiralty Charts of that scale dont show all the inshore buoys.

In my neck of the woods there are quite a few unlit buoys which due to the large tidal range can be a long way offshore at HW .

IMHO they shouldnt be allowed.
 
|If they can get a lighthouse on the wrong side of a harbour entrance, transposed from admiralty chart incorrectly twice...July 2001 and Jan 2003 revisions on C18 then to miss one bouy must be quite easy.

Hopefully its corrected now but it was Pta Sarridal on the entrance to Cedeira, just up the coast from Coruna... in case any body is heading that way with an older chart.

Well equipped. As for the facts regarding preparation and competency, you were, by you own admission, navigating at night with one out-of-date chart of an unsuitable scale, which you have clearly demonstrated to be inadequate for your purposes. Hmm?
I do, as it happens, have a little experience of night-time navigation, a bit of it on that very stretch of coast.
 
Thanks Talbot.
Our C28, and also Y9 of The Wash, had both been updated with every correction issued. No correction had been issued for this bouy. It would appear, from what has been said, that Imray do have the habit of missing information off charts, or indeed putting navigation marks in the wrong place. If a chart is not correct when issued then a user will have little chance of verifying all the data sufficient to guarentee all the data is correct. I will not be buying Imray charts again. Thanks for your help. Paul

I'm sorry to be so pushy about this, but, from Imray's site - Please Note : Charts that have been superseded by new editions cannot be corrected. Correction Notices on this site are correct to the date specified on the notice, please check back from time to time to keep your charts up to date

and from the corrections page for C28, it is clear that a new edition was printed in June 2004. Therefore, your chart was out of date and could not be updated. It was obsolete, and they had published a note to this effect.
Build a proper folio of appropriate charts and update them, which includes replacement when new editions are published.
I think your indignation about this buoy is ridiculous.

FWIW, compare Imray's published corrections for a given area and compare with the Admiralty equivalent - chalk and cheese.

Sorry again to be so stroppy - but look at the situation you got into, and think about it. It's not Imray's fault.
