Regulation 17 



Pilot Ladders 



Ships engaged on voyages in the course of which pilots are likely to be 

 employed shall comply with the following requirements respecting pilot 

 ladders : — 



(a) The ladder shall be kept in good order and for use only by ofl&cials 

 and other persons while a ship is arriving at or leaving a port, and 

 for embarkation and disembarkation of pilots. 



(Z>) The ladder shall be secured in a position so that each step rests 

 firmly against the ship's side and so that the pilot can gain safe 

 and convenient access to the ship after climbing not less than 

 5 feet (or 1-5 metres) and not more than 30 feet (or 9 metres). 

 A single length of ladder shall be used capable of reaching sea 

 level in all normal conditions of trim of the ship. Whenever the 

 distance from sea level to the point of access to the ship is more 

 than 30 feet (or 9 metres), access from the pilot ladder to the ship 

 shall be by means of an accommodation ladder or other equally 

 safe and convenient means. 



(c) The treads of the ladder shall be not less than 19 inches (or 48 



centimetres) long, 4^ inches (or 11-4 centimetres) wide and 1 inch 

 (or 2-5 centimetres) in depth. Steps shall be joined in such a 

 manner as will provide a ladder of adequate strength whose treads 

 are maintained in a horizontal position and not less than 12 inches 

 (or 30 -5 centimetres) or more than 15 inches (or 38 centimetres) 

 apart. 



(d) A man-rope, properly secured, and a safety line shall be available 



and ready for use if required.

(i) The rigging of the ladder and the embarkation and disembarka- 

 tion of a pilot is supervised by a responsible officer of the 

 ship.
