Method of tonnage measurement

(1) The owner and the master of a ship to be measured shall make it available
for measurement by a surveyor and afford all necessary facilities for its
survey and measurement and shall produce such plans, drawings, specifications
and other documents relating to the ship that the surveyor may require for his
use or retention.

(2) The gross and net tonnages shall be determined in accordance with
regulations 6 and 7 of these regulations provided that in the case of novel
types of craft with constructional features which render the application of
the provisions of these regulations unreasonable or impracticable, the gross
and net tonnages shall be determined as required by the Director.

expressed in metres to the nearest centimetre.

(4) Gross and net tonnages shall be expressed as whole numbers, decimals being
