[Talk-GB] [talk-gb] Local authority boundaries in the Hebrides

[Colin Smale]

Hi Edward,
That is exactly the reason.  Local authority jurisdiction extends to low water (MLW or MLWS), the coastline is defined as high water MHW or MHWS).
In England and Wales I know it's defined as MLWS but I have a niggling memory of the legal definition being subtly different in Scotland.

I can't recall seeing LAT begging used outside of a shipping context before, but I will be sure to look into your link, thanks!

Regards, Colin
