UK, UK Overseas Territories and UK Crown Dependencies Maritime Limits and Law of the Sea

We have a team of experts who specialise in technical aspects of maritime baselines, limits, zones and boundaries.

Maritime Limits

The limits and boundaries of the UK, UK Overseas Territories and UK Crown Dependencies are available from this website in accordance with Articles 16, 74 and 84 of the United Nations Convention on the Law of the Sea.

Limits are calculated from the normal baseline (the low water line on the largest UKHO charts) and limits are maintained by UKHO. Please note that these shape files will only be updated annually and that all limits and diagrams are released under the Open Government Licence.

Current Limits illustrations are available to view or download below.
