Sec. 183.315  Reference depth.

    Reference depth is the minimum distance between the uppermost 
surface of the submerged reference area of a boat and the surface of the 
water measured at the centerline of the boat, as illustrated in Figure 
10. If there is no deck surface at the centerline of the boat from which 
a measurement can be made, the reference depth is the average of two 
depth measurements made on opposite sides of, and at an equal distance 
from, the centerline of the boat.
