These small but useful class have recently been adopted for use by Royal Navy; a dozen or so are in service on Earth, and more on Mars. Their 9 HP petrol engine (Engine size 0.075, weight one-quarter ton) has proven somewhat balky and delicate in service; 75 gallons (a quarter-ton) of kerosene fuel are carried, giving the vessel a week's endurance at its top speed of 20 knots. A cramped cabin under the "turtleback" forward deck provides four bunks, a simple galley, etc.; the engine and fuel tanks are under the main deck. Canvas awnings and canopies can be erected to shield the crew from the sun or weather. A winch is fitted to raise about a ton of cargo; about two tons can be carried.
