On a boat we navigate the other side, but it does depend on the local buoyage system , which if at sea, depends on the tidal streams, on rivers we navigate on the right.
Not used canals to 'boat' on ,but I imagine, it follows the navigation rules.
On a bicycle, if on an off road route then I follow the Highway code and use the Left hand side of the shared path, slowing or stopping for pedestrians, they have the right of way, as far as I am concerned.
But on a cycle path, I become a 'Psychopath' ! It's my dedicated route to use, and I will ride at speed on it, I don't give way , unless impeded by oncoming traffic, if your a Ped, on the Pysco' then expect to be warned, I'm not willingly going to concede.
I am told ,or verbally abused to use the Cycle way enough , so by the same token ,keep of my cycle paths!
In Sarfend we haven't many anyway, , apart from the prom, which is an abomination, narrow and poorly constructed, with amberling Peds wondering around to access the beach.
