                          2 Horsepower or Less
 
Sec. 183.320  Preconditioning for tests.

    A boat must meet the following conditions for at least 18 hours 
before the tests required by Sec. Sec. 183.325, 183.330, and 183.335:
    (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) Two-fifteenths of the persons capacity marked on the boat.
    (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 the maximum horsepower 
marked on the boat; less the persons capacity marked on the boat.
    (c) The weights required by paragraph (b) of this section are 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 mid-length 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 in lieu of this equipment. The quantity of weight 
used for this purpose depends upon the maximum rated horsepower of the 
boat being tested and is specified in Column 2 of Table 4 for the 
swamped weight of the motor and controls.
    (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 the 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.
