I beleive it's what's called a 'grey area'. Custom and practice is that you can land between the low and high water marks as this is 'common land' (owner by the Queen, I think), but I don't think you'll find this is definitive.
Be careful of rule 5 (OK, before the bitching starts I know you are landing and taking off in accordance with normal aviation practice etc etc, but it's probably a good rule to follow when there are people about), and of course have complete confidence that you can restart the machine....
Cromer: I went to one of their 'heli fly-in's' last year....I was the only one who turned up! Nice crabs though
