Sections 54 to 58 provide for the Continuation or Restoration of the Character A 1 for further periods.
Ships Classed A 1 in Red.—Section 60 provides for the Survey and Classing of Ships A 1 in Red, which is also a Class of vessels fit for the safe conveyance of dry and perishable goods to and from all parts of the world. They are allowed to retain this Character upon Special Survey, for terms in no case exceeding two-thirds the periods originally assigned to them.
They are also subject to Annual Survey, and to the half-time Survey prescribed in Section 34.
Ships Classed Æ, for the conveyance of dry and perishable goods on shorter voyages, and for the conveyance of cargoes not in their nature subject to sea damage on any voyage.
Section 61 requires that they should be submitted to Annual Survey, and to Special Survey within periods not exceeding four years.
Ships Classed E.—For the conveyance of cargoes not subject to sea damage on any voyage.
Section 65 requires that they should be submitted to Annual Survey, and to Special Survey within periods not exceeding three years.
Provision is made in the Rules for the Classification of Composite Ships; also of Foreign-built Ships constructed not in accordance with the Rules.
As all vessels are required to be surveyed periodically, the date of Survey is the criterion of their state of efficiency at that time only.
