PART 183--BOATS AND ASSOCIATED EQUIPMENT--Table of Contents
 
 Subpart G--Flotation Requirements for Outboard Boats Rated for Engines 
                        of More Than 2 Horsepower
 
Sec. 183.220  Preconditioning for tests.

    A boat must meet the following conditions for at least 18 hours 
before the tests required by Secs. 183.225, 183,230, and 183.235:
    (a) Manufacturer supplied permanent appurtenances such as 
windshields and convertible tops must be installed on the boat.
    (b) The boat must be loaded with a quantity of weight that, when 
submerged, is equal to the sum of the following:
    (1) The sum of 50 percent of the first 550 pounds of the persons 
capacity marked on the boat and 12\1/2\ percent of the remainder of the 
persons capacity.
    (2) Twenty-five percent of the result of the following calculation, 
but not less than zero: The maximum weight capacity marked on the boat; 
less the weight shown in Column 6 of Table 4 for maximum horsepower 
marked on the boat; less the persons capacity marked on the boat.
    (c) The weights required by paragraph (b) of this section must be 
placed in the boat so that the center of gravity of each amount of 
weight required by paragraphs (b)(1) and (b)(2) of this section is 
within the shaded area illustrated in Figure 11. The location and 
dimensions of the shaded area are as follows:
    (1) The shaded area is centered at the mid-length of the passenger 
carrying area and at the mid-breadth of the boat;
    (2) The length of the shaded area, measured along the centerline of 
the boat, is equal to 40 percent of the length of the passenger carrying 
area of the boat; and
    (3) The breadth of the shaded area, measured at the midlength of the 
passenger carrying area, is equal to 40 percent of the breadth of the 
passenger carrying area of the boat.
    (d) Weight must be placed in the normal operating position of the 
motor and controls and the battery in lieu of this equipment. The 
required quantity of weight used for this purpose depends upon the 
maximum rated horsepower of the boat being tested and is specified in 
Columns 2 and 4 of Table 4 for the swamped weight of the motor and 
controls and for the submerged weight or the battery, respectively.
    (e) Permanent fuel tanks must be filled with fuel and each external 
opening into the fuel tank must be sealed.
    (f) The boat must be keel down in the water.
    (g) The boat must be swamped, allowing water to flow between the 
inside and outside of the boat, either over the sides, through a hull 
opening, or both. Entrapped air in the flooded portion of the boat must 
be eliminated.
    (h) Water must flood the two largest air chambers and all air 
chambers integral with the hull.
