Updating charts

[PhillM]

I was wondering if there is an easy way to get a list of all updates needed for an Admiralty Chart Folio?

I have found the website :http://www.ukho.gov.uk/nmwebsearch/NMsByChartNumber.aspx?filter=1

After spending ages wondering why the chart numbers from the folio don't work, I found the small print on the chart that says "derived from ...." and that seems to give me a list of corrections to apply.

Is this the best way or is there a shortcut that gives all corrections required for the folio?

Thanks Tex, the problem is I cannot see where to get the NM's from for the folio? Am I being stupid / blind and just missing the link??

Select the "Leisure NMs" tab and then select your folio.
Can take a few minutes to download the pdf. file

Brilliant, that's superb and really helpful. Thank you.

I have just got the NM's for Solent and it looks like I am going to have a few hours fun updating my 12 edition, this weekend ..... Perhaps it might be quicker to buy the 13th edition instead and then try to keep it ip to date!

Unless the Hydrographic Office have changed their policy, as soon as a new folio is issued corrections for the old disappear. When you buy a new folio you must download the NMs for that issue pdq 'cos it won't be in date and there is no warning of new issues being made (which erases the old NMs). There is also no guarantee the same charts are going to have the same numbers in the new issues.
The easy way is to buy real charts from real suppliers and they arrive fully updated to the day you buy them and then you can update them with the weekly NMs like all good 3rd Officers do.

What do you mean by "real charts from a real supplier?" I thourght that Admiralty Charts were the best???

The current NM for Solent includes the previous for 12th edition. I have downloaded them and spent the afternoon updating mine. However, as there are so many changes and the Solent is my prime sailing ground, I will buy the 13th edition before the spring.

Mind you, if I was a bit rusty at chartwork when I started, I'm not now

I mean full size charts from a chart supplier, like Kelvin Hughes, which come annotated with all the current NMs. Leisure folios don't get updated on the shelf and unless you buy right at the start of the issue, and even then, are very probably missing changes.

I think the whole chart correction business is sometimes taken a bit far, and I was very pleased to read an article in the RYA rag by that Tom Cun*lliffe, RYA Examiner, being quite laid back about using out-of date charts. We recently acquired a whole bunch of second hand charts for our possible Orkneys cruise next year and I am sure they will do fine. Kapitanleutnant Gunther Prien managed very well without the latest corrections from UKHO when he visited the area. (If anyone thinks that's in poor taste I apologise for giving offence but am happy to say more about my choice of illustrative example.)

Thanks for the clarification and advice. I will give that some thourght. As it happens I have a client in the same building as then in Southampton, so next time I am in town I will pop in for a chat.

What heresy! You mean you haven't allocated chart updating to the junior member of your triumvirate?
I have a varying regime, depending on how miserable it is outside, but use the UKHO website (it seems to remember the chart numbers) to print off a small print version of all the changes since my last update, graze through them and mark up any I think are v. important on my charts. Things like buoys moving, lights changing and I print off and paste any of the detail plans that tickle my fancy. My Orkneys charts are OSGB36 and there is quite a shift up there from WGS84 so there are big RED letters reminding me.

List price of one Admiralty Standard chart is about £23, a leisure folio is listed at £44.
A standard chart purchased from an Admirastly chart agency is kept corrected up to the moment you purchase it, thats the reason for the big price difference.
They are also twice the size, so unless you have a very large chart table, your expensive chart will live folded in half until it falls apart.
Nice thing with the leisure charts is you can keep the working chart in the placcy sleeve, and just use a fine white board marker or chinograph pencil to mark positions, courses etc, keeps them dry

Noticer to Mariners for Leisure folios contain all the corrections for the previous edition.
In my case, I'm happy to keep a folio until the second subsequent edition is published, then I'll renew.
Apply common sense to what corrections you use, I dont bother with a depth chnage from 98m to 100m

There are some corrections which really should be applied. If Mr TC is happy to ignore chart corrections and navigate on out of date charts thats fine by me, maybe he can afford the penalty for romping the wrong way up a traffic lane which he did not know about, I cannot.

Got me thinking though, maybe I should take my charts to work with me and get some hapless cadet to correct them, good practise before being let loose on the real thing
