The limits of your fishing zone are vast and cover the whole Cornish coast.
The Northern border has been set as the point to the South West of Welcombe, Devon. You may fish anywhere up to the Southern side of the point marked on the map. No fishing North of here.
The fishing zone then covers the whole of Cornwall, down the North coast , around at Lands end and back up the English Channel (obviously private land is out of the question). The Southern county border is the River Tamar. You may fish anywhere up to the Cornish side of the river. Crossing the Tamar Bridge will take you out of bounds.

Fishing outside of the allocated zone is strictly prohibited and anglers seen or heard doing so will be disqualified.
