Boating on the tidal Thames presents a unique set of challenges, but for the experienced it can be a most rewarding experience. 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 you can encounter waves over a metre tall and tidal flows in excess of four knots.
The general directions of the Port of London (PLA) require a number of vessels, and those of 13.7m or more in length overall, to have an operational VHF radio on board.
The PLA has information and a very useful guidance document available at: http://www.boatingonthethames.co.uk/Narrow-Boating
