If I sail up the Thames in my superyacht, then decide to take off and land my helicopter on my yacht, is there any law to prevent this?
(Based on the fact the Thames is a waterway, maritime rules and all that)
If it is legal, do I have to be steaming up and down for this to be legal, or would it still be legal if I was moored up alongside or on anchor in the middle (or mooring buoy)?
Enquiring minds want to know..
