(i) The minimum freeboards for flush deck steamers are obtained
by an addition to the above Table at the rate of 1½ inches for every
100 feet of length.
(ii) The freeboards at intermediate lengths are obtained by inter-
polation.
(iii) Where c exceeds 0·68, the freeboard is multiplied by the
factor (\frac{c + ·68}{1·36}).
(iv) Where D exceeds (\frac{L}{15}) the freeboard is increased by
(\left{D - \frac{L}{15}\right} R) inches, where R is (\frac{L}{130}) at lengths less than 390 feet, and
3 at 390 feet length and above.
In a ship with an enclosed superstructure covering at least 0·6 L
amidships, with a complete trunk, or with a combination of intact
partial superstructures and trunk which extends all fore and aft,
where D is less than (\frac{L}{15}), the freeboard is reduced at the above rate.
Where the height of superstructures or trunk is less than the standard
height, the reduction is in the ratio of the actual to the standard
height.
(v) Where the actual depth to the surface of the freeboard deck
amidships is greater or less than D, the difference between the depths
(in inches) is added to or deducted from the freeboard.
