horizontal.
    (2) Any point on either the forward or aft reference area is above 
the surface of the water.
    (3) The reference depth at the reference area that is opposite the 
reference area that is above the surface of the water is 12 inches or 
less.
    (b) Quantity of weight used. Load the boat with quantity of weight 
that, when submerged, is equal to the sum of the following:
    (1) One-half the quantity of weight required by Sec. 183.320(b)(1).

the center of gravity of the quantity of weight is located within the 
shaded area illustrated in Figure 12, the center of gravity of the 
amount of weight placed on the floor of the boat is at least 4 inches 
above the floor and the center of gravity of the amount of weight placed 
on a seat is at least 4 inches above the seat. The location and 
dimensions of the shaded area are as follows:
    (i) The shaded area is centered at the mid-length of the passenger 
carrying area;
    (ii) The length of the shaded area is equal to 70 percent of the
