I was just reading further, and this might be of comarative interest:
"Who Owns Foreshore?
In British Columbia, the Province owns nearly all freshwater and
sal****er foreshore. Land adjacent to foreshore maybe privately owned,
but in common law the public retains the privilege or "bare licence" to
access the foreshore."
from:
http://www.lwbc.bc.ca/02land/tenuring/privatemoorage/
Note the point about "access to the foreshore". Again, quite proper
IMHO.
