A. H. Y. MARCH 30, 1912. * * * * * DRAFT AMENDMENT OF GENERAL RULES. (1) _Boats._--All boats shall be constructed and properly equipped as provided by these rules, and shall be of such form and proportions that they shall have sufficient freeboard, and ample stability in a seaway, when loaded with their full complement of persons and equipment. All thwart and side seats must be fitted as low in the boat as practicable, and bottom boards must be fitted so that the thwarts shall not be more than 2 feet 9 inches above them. All boats and other life-saving appliances are to be kept ready for use to the satisfaction of the board of trade. Internal buoyancy apparatus may be constructed of wood, or of copper or yellow metal of not less than 18 ounces to the superficial foot, or of other durable material. SECTION (A). A boat of this section shall be a lifeboat of whaleboat form, properly constructed of wood or metal, having for every 10 cubic feet of her capacity, computed as in rule (2), at least 1 cubic foot of strong and serviceable inclosed air-tight compartments, so constructed that water can not find its way into them. In the case of metal boats an addition will have to be made to the cubic capacity of the air-tight compartments, so as to give them buoyancy equal to that of the wooden boat.
