1234 TREATIES If the sheer is less than the standard sheer defined above, the minimum freeboard is obtained by adding to the figures in the table one-seventh of the difference between the standard sheer and the actual mean sheer measured at the stem and stern post; no deduction is to be made from the freeboard on account of the sheer being greater than the standard sheer or on account of the camber of the deck. (iii.) All decked lifeboats shall be fitted with efficient means for clearing the deck of water. REGULATION XXVII. Motor Boats. Moto bots.

The motor and its accessories shall be suitably enclosed to ensure operation under adverse weather conditions, and provision shall be made for going astern. (d.)
