Safe passage requires a sound knowledge of the effects of the tidal stream, including the resultant currents and variable depths which are not found on the (non-tidal) canal system.

The passage between Teddington and Limehouse is only recommended for the experienced boater, as waves over a metre in height and tidal flows in excess of four knots can be encountered.

The PLA’s General Directions require a number of vessels, and those of 13.7m or more in length overall, to have an operational VHF radio on board, but narrow boats greater than 13.7m in length overall, and which are navigating only between Brentford and Teddington, are exempt. However, any narrow boat wishing to complete the “London Ring” (the Grand Union Canal and then transiting from Limehouse to Brentford) are not exempt from this General Direction.
