Fishing Vessel Safety Regulations

18 (1) Subject to subsection (2), where the propulsion shafting of a fishing vessel is driven by a diesel or a gasoline engine, the intermediate shaft shall

• (a) be made of material having a tensile strength of not less than 372 MPa; and

• (b) have a diameter not less than that obtained by the following formula:

  d = 106.41 cubic root (H/R) x [cubic root (414/S) or 0.85, whichever is the greater]

  where

  d =

  diameter of the intermediate shaft in millimetres,

  H =

  brake kilowatt power of the engine at continuous rating,

  R =

  revolutions per minute of the intermediate shaft at continuous rating,

  S =

  tensile strength of the intermediate shaft material in megapascals.

(2) Where a fishing vessel is operated exclusively in fresh water, the diameter of the intermediate shaft may be 1.75 per cent less than the diameter obtained by the formula set out in subsection (1).

(3) Where the propulsion shafting of a fishing vessel is not driven by a diesel or gasoline engine, the size of the intermediate shaft shall be determined by the Board.
