Motor-boats are vessels with diesel engines that are below 20 metres in length. Typically, motor-boats can be hired with a skipper (normally at an extra fee of €250), however he will not live aboard the vessel and will work alone. Charter yachts measure over 20 metres in length, and typically come with at least 2 crew members: a captain and a steward/stewardess. The crew on-board a yacht are typically permanent and included in the price (unless otherwise stated). The level of service on-board yachts is superior to that of motor-boats, and this is reflected in the price. See yachts for charter
