Hang on, then we reach a sign and helpful arrow that sends us back in the same direction.
What it really trying to convey is the this is the Disabled Landing Point. Some vertical lines at the blunt/start end of the arrow would help.
The word 'point' does not really help either as it is in fact a landing an 'area' or zone.
And once you've landed, is it suitable to moor the boat one might wonder. Is a "Landing Point" for boats the equivalent to the "Drop off" for cars at supermarkets and train stations....
And then wonder some more....given that there's some disabled landing, there'll logically follow at some point the revere, some disabled boarding.....hopefully that's not somewhere else....
