Imagine a boat with 85 computers and likely you are envisaging something reminiscent of the QEII. But you might not be thinking quite along the lines of the Boatel. The Boatel is merely the most luxurious houseboat afloat, and its operators rightly describe it as being more like a hotel. The sleek two-storey vessel, which has just begun operating on the Murray River from Mannum in South Australia, is virtually self-contained and boasts five ensuite king bedrooms and a commercial-grade kitchen. Practically everything that opens and shuts is controlled electronically.
