March 2013 – RAF crew battled winds and rain to rescue a seriously injured French fisherman from a stricken vessel, 50 miles to the west of Welsh port town Milford Haven in the Irish Sea. English and French coastguards, HMS Echo and RNLI lifeboat Angle also attended the rescue. Photo: RAF
So …what is the length of a piece of string?
Well, it seems it depends on many things like temperature/tension in the string/material/accuracy of equipment etc.
OK I’m sure you get my drift; and it’s a similar situation when you ask “what is the length of UK coastline”.
Even experts disagree but here is a selection of answers when doing an Internet Search:
Wikipedia quotes 19,491miles but also gives the CIA Factbook 7,723miles.
http://en.wikipedia.org/wiki/Coastline_of_the_United_Kingdom
UK Coast Guide states around 7,760miles.
http://www.ukcoastguide.co.uk/
Panoramic Earth website quotes nearly 19,500miles.
http://www.panoramicearth.com/article/uk-ocean-cruises.html
The RNLI also state around 19,000miles
The most explicit answer comes from the British Cartographer’s Society which qualifies its figure of 19,491miles at mean high water mark based on 1:10,000 scale maps, however this is for Principle Islands only!
http://www.cartography.org.uk/default.asp?contentID=749
The general consensus is at least 19,491miles which is why it is utterly surprising that the Maritime Coastguard Agency quote “over 10,500 Nautical miles of Coastline” which equates to over 12,083miles.
It is extremely worrying that the agency responsible for our coastline has underestimated the scope of their remit. So it was rather tongue in cheek that the Coastguard SOS team released a map showing the lost coastline as that responsible by the Maritime Rescue Coordination Centres that are due to close under the current disastrous “modernisation” plan.
Joking aside, how can an agency convince all the general public & stakeholders in Maritime Safety that they have any credible concept of how big the job is when they have something like 160% error rate! This error has been queried with the MCA but they remain unfazed about the lack of accuracy.
The Coastguard SOS campaign group has used the 19,491miles figure in many of its communications as it comes from impeccable sources of both the BCS and Ordinance Survey (the UK Map authority). Indeed we approached OS for a conclusive figure.
OS state that the figure is dependent on the many factors discussed before and pointed us to the BCS site and figures.
How shocking it is to find that a comprehensive answer to the question has already been established via an MP and that it concludes that the figure is around 24,144miles!

On 23rd June 2010 the following answer was given to an MP’s question:
“ The Parliamentary Under-Secretary of State, Department for Communities and Local Government (Baroness Hanham): Information provided by Ordnance Survey for Great Britain and by Land and Property Services, an agency of the Department of Finance and Personnel for Northern Ireland, indicates that the lengths of the coastlines at mean high water (MHW) and mean low water (MLW), (mean high water springs [ordinary spring tides] and mean low water springs in Scotland) are:
| Country | Length of Coastline at Mean Low Water (MLW) [Miles] | Length of Coastline at Mean High Water (MHW) [Miles] |
| England | 8,417 | 9,462 |
| Northern Ireland | 620 | 542 |
| Scotland | 14,675 | 13,186 |
| Wales | 2,323 | 1,999 |
| United Kingdom | 26,035 | 25,189 |
These coastal lengths include all offshore islands, and land areas which are above MLW.The precise length of coastlines will vary from time to time due to natural and gradual changes arising from coastal erosion and silt deposition.”
YES, I believe there is a mistake & that UK lengths are swapped round – (I base this on the fact that the same methodology should give consistent differences between the two figures). There is something of a debate going on about this information here http://www.edparsons.com/2010/06/call-yourself-a-geographer/
Without getting into any further debate, I think that these are figures that truly reflect the lengths of Coastline:
| Country | Length of Coastline at Mean Low Water (MLW) [Miles] | Length of Coastline at Mean High Water (MHW) [Miles] | |
| England |
9,462 |
8,417 |
|
| Northern Ireland |
620 |
542 |
|
| Scotland |
14,675 |
13,186 |
|
| Wales |
2,323 |
1,999 |
difference |
| United Kingdom |
27,080 |
24,144 |
2,936 |
Taking the 24,144miles figure, this is a staggering 200% greater than that quoted by the MCA.
Now you might ask Why this is significant, well not only is it indicative of the complex issue of assessing the scale of the coastline that needs covered by our volunteer Coastal Rescue Officers, RNLI and Independent rescue crews. It is also an excellent gauge of every coastal feature that invariably has a name or even several names for the same one. At low water our coastline increases by nearly 3,000miles, adding yet more features & names to any database!
It’s a good job that OS are partners in the current project with the MCA to capture all the local names & descriptions of features around the whole UK coastline, because of the two organisations, OS has some measure of the task!
This project is called FINTAN http://www.ordnancesurvey.co.uk/oswebsite/news/2012/06/collecting-names-from-coast-to-coast.html
It’s a very ambitious project to have EVERY name of EVERY feature on our coastline in one database. The information is being gathered from multiple sources, in multiple local languages (Welsh, Gaelic etc) and by people that will have not have access to the system. Eventually this database will be integrated with several other Computerised Search & Rescue tools as mentioned in this blog: http://coastguardsos.com/mission-impossible-the-mcas-future-coastguard-system/
It makes you wonder on what basis the MCA was able to justify the cost of this new database. I just hope that they were not using the coastline figure from their website as a guide to acceptable cost per mile; otherwise the final bill will be in error by 200%.

You can see that it is no wonder the UK developed the first Coastguard service over 191 years ago, for a relatively small country, we have a high ratio of coastline regardless of what base measurement is chosen.
It can be said that the UK punches above its weight when it comes to coastline and Maritime Safety.
This is one of the reasons the UK needs to continue to build on the expertise, knowledge and hard learnt lessons that HM Coastguard has experienced in its history.
The Maritime Coastguard Agency has amply demonstrated that it can get facts wrong with the particular subject of coastline. The Coastguard SOS campaign group has striven to enter into dialogue with the MCA regarding the ongoing changes to HM Coastguard.
With the promise of a meeting between the Group and the MCA, we hope to raise a considerable number of concerns including the deepening staffing crisis and safety issues.
Our ‘piece of string’ has grown in a similar way to Coastguard staff being stretched – something is bound to snap and we are becoming increasingly worried if there will be a service left for us to defend.
