Deck arrangements consist of the following: A hatch to the fo'castle, followed by; the emplacement for the rapid-fire gun. Following this is the steering shelter containing duplicate controls, &c., for the engine room and for the steering. Immediately aft of the steering shelter is the bridge deck, located on top of the engine room trunk house. The entire after half of the vessel is a clear sweep of deck with the exception of a booby hatch to crews' quarters well aft. The boats are arranged for wireless with foremast and jigger mast. Rail stanchions in the way of the torpedo tube are hinged down, giving clear sweep to the tube for firing purposes. PROVISION FOR OFFICERS AND CREW. Below decks ample space has been provided for the crew and officers. The forepeak is arranged for chain lockers and bosun's gear lockers, followed by ship's galley, which has two pipe berths. Next to the galley is located the officers' cabin and wireless room, which is entered by a hatch from the steering shelter. This cabin accommodates two officers and includes lavatory, officers' desks, wireless desk and folding mess table. Next aft is the machinery space, in which are located the three eight cylinder Duesenberg motors, a three k.w. universal lighting set, the necessary oil tanks, batteries and a work bench. The next compartment contains fuel tanks, with 1300 gallons capacity. Aft of this compartment is located the crew's quarters, berthing eight men, with lavatory attached. The hull is divided into six water-tight compartments by steel bulkheads. The hull is of wooden construction, as developed for this service by the builders. The 72-footers develop a speed of twenty-eight knots and have a cruising radius exceeding 1200 miles. The design of the hull is the concave bottom, square bilge type, developed for this particular service. It furnishes a steady gun platform, which, with the necessary speed, is the most vital feature of a submarine chaser. The demand for speed and stability was borne out by the experience of the Russian and Italian navies in their active work and no consideration at all is given propositions from these two countries which do not range well about twenty-five knots. Exceptional success was attained by the Russian Black Sea and by the Italian high speed fleets in actual use and their demand for exceptional speed was based on experience. It is a well known fact that the Russian government was successful in patrolling its shores and in protecting its harbors and shipping. The Italian government also was exceptionally successful in maintaining its mercantile fleet in comparative safety and in protecting its harbors against the offensive work of enemy submarines. The entire Italian fleet of submarine chasers consists of high speed, high powered motor patrol boats, most of which were equipped with American made motors. CATALOGUED AS "PATROL BOATS."
