Once inside the lock, there is always water in the port (does not dry out). However, the water level varies according to sea levels: contact the lock manager (+33 (0) 2 31 98 72 82 or VHF channel 17) to check the water depth
The Old Basin (Vieux Bassin) is the marina of Honfleur. Boats must moor alongside each other on the visitors pontoon on the right hand side of the Old Basin as you go in (under a lifting bridge). Boats 14 metres or more in length are not admitted to the Old Basin and are invited to moor up 200 metres beyond the lock entrance, alongside the quai or on the pontoons with water and electricity.
Contact the lock manager for times of the lifting bridge also.
