River Draught

The 'timeline' gives the nominal depth of the navigation channel (as defined by the Environment Agency for the non-tidal Thames)

The difference between the nominal depth and the draft of your vessel is the clearance under your keel.

Notwithstanding the nominal depths, it is advisable to use some form of depth gauge to ensure you do not run aground.
