Not only the ducks and coots!

Although the German-British composer George Handel composed « The Water Music » for fifty musicians on a barge cruising along the River Thames, for the past century the noise of petrol-engined boats deterred the gentle sounds of music along the river. The silence of cruising along in an electric boat is ideal for playing or singing music. PBG rules mean that you must have a least three people on board during the cruise – a trio, string or barber shop – not nothing stops you increasing to a sextet or a small orchestra.
