A reference in these Regulations to the length of a ship, being a ship that is a passenger ship, shall be read as a reference to the length measured between the perpendiculars at the extremities of the deepest subdivision load waterline of the ship.

(2)

A reference in these Regulations to the length of a ship, being a ship that is a cargo ship, shall be read as a reference to:

(a)

a distance equal to 96 per cent of the total length of the ship measured on a waterline that is:

(i)

in the case of a ship other than a ship referred to in subparagraph (ii) or (iii) — at a distance, from the top of the keel, equal to 85 per cent of the least moulded depth of the ship;

(ii)

in the case of a wood ship or a composite ship — at a distance, from the lower edge of the keel rabbet, equal to 85 per cent of the least moulded depth of the ship; or

(iii)

in the case of a ship in which the form at the lower part of the midship section is of a hollow character or in which thick garboards are fitted — at a distance, from the point where the line of the flat of the bottom continued inwards cuts the side of the keel of the ship, equal to 85 per cent of the least moulded depth of the ship; or

(b)

if the distance measured from the fore side of the stem to the axis of the rudder stock on that waterline is greater than the distance applicable under paragraph (a) — that greater distance.

(3)

In the case of a cargo ship designed with a rake of keel, the waterline on which the total length of the ship is to be measured for the purposes of subregulation (2) shall be parallel to the designed waterline.
