INTERNATIONAL CONVENTION SAFETY OF LIFE AT SEA. ~ 227 



The number and arrangement of the boats, and (where they are allowed) of the pon- 

 toon rafts, on a vessel depend upon the total number of persons which the vessel is in- 

 tended to carry; provided that there shall not be required on any voyage a total capacity 

 in boats, and (where they are allowed) pontoon rafts, greater than that necessary to ac- 

 commodate all the persons on board. 



Article 41. 



STANDARD TYPES OF BOATS — PONTOON RAFTS. 



All the lifeboats allowed for a vessel shall comply with the conditions fixed by this 

 Convention and Articles XXVII to XXXII of the Regulations annexed hereto; the same 

 articles describe the standard types which are divided into two classes. 



The conditions required for the pontoon rafts are given in Article XXXIII of the 

 same Regulations. 



Article 42. 



STRENGTH OF BOATS. 



Each boat must be of sufficient strength to enable it to be safely lowered into the 

 water when loaded with its full complement of persons and equipment. 



Article 43. 



ALTERNATIVE TYPES OF BOATS AND RAFTS. 



Any type of boat may be accepted as equivalent to a boat of one of the prescribed 

 classes and any type of raft as equivalent to an approved pontoon raft, if the Administra- 

 tions concerned are satisfied by suitable trials that it is as effective as the standard types 

 of the class in question, or as the approved type of pontoon raft, as the case may be. 



The Government of the High Contracting Party which accepts a new type of boat or 

 raft will communicate to the Governments of the other Contracting Parties particulars of 

 the trials made. It will also inform them of the class in which a new type of boat has 

 been placed. 



Article 44. 



EMBARKATION OF THE PASSENGERS IN THE BOATS AND RAFTS. 



Suitable arrangements shall be made for embarking the passengers in the boats. 

 In vessels which carry rafts there shall be a number of rope ladders always avail- 

 able for use in embarking the persons on to the rafts. 



Article 45. 



CAPACITY OF BOATS AND PONTOON RAFTS. 



The number of persons that a boat of one of the standard types or an approved pon- 

 toon raft can accommodate is determined by the methods indicated in Articles XXXIV to 

 XXXIX, inclusive, of the Regulations annexed hereto.
