(1) Where the effective length of superstructures
and trunks is 1L, the deduction from the freeboard shall be 350 mm
at 24 m length of ship, 860 mm at 85 m length and 1,070 mm at 122
m length and above. Deductions at intermediate lengths shall be obtained
by linear interpolation.
(2) Where the total effective length of superstructures
and trunks is less than 1L, the deduction shall be a percentage obtained
from the following table:
