The "Cruiser Stern" narrowboat has a much larger rear deck, taking its inspiration from cabin cruiser style boats, which is typically 8ft in length. This is generally protected by a "taff" rail that can incorporate bench seating. The boats controls are provided on a control tower mounted on the rear deck and the engine is located beneath the rear deck.
The larger rear deck provides more social open space when out cruising or for sitting outside in fine weather.
Reduced interior cabin space for a given length of boat. The location of the controls of the rear open deck mean that the helmsman is very exposed to the elements. As the engine is located beneath the rear deck, there is increased opportunity for rainwater to collect in the engine bilge. [an error occurred while processing this directive]
