Here is an excellent way for two people to see the Thames from a new perspective and take in some of the great sights of our capital city from the river. Jump aboard this small, light and high-speed powerboat, otherwise known as a RIB, and get ready for some fast fun. There is always a safety briefing to start with before being kitted out with the kind of gear needed for this waterborne experience. Then it's all systems go as the skipper takes you up and down the meandering river penetrating central London, pointing out areas of interest and telling interesting tales.
