B 200 Construction symbols

201 The construction symbol will be assigned to ships built under the supervision of the Society.

202 The construction symbol will be assigned to ships built under the supervision of a recognized classification soci-

ety and later assigned class with the Society. For such shipsthe class notations which the Society considers to have theequivalent intent will be assigned.

203 Ships other than those described in 201 and 202, will not be assigned construction symbol when classed with the Society.

B 300 Main character of class

301 The notation 1A1 will be assigned to ships with hull, ma-chinery, systems and equipment found to be in compliance withapplicable rule requirements as given in Pt.2, Pt.3 and Pt.4.

302 The notation 1A1 will also be assigned to ships designedand constructed in accordance with the rules of another classi-fication society, and later assigned class with the Society.

B 400 Service restrictions

401 The service area notation R followed by a number or aletter will be assigned to ships with certain modifications to ar-rangement, equipment or scantlings, in relation to ships builtfor unrestricted trade.

The service area restrictions, given in nautical miles and repre-senting the maximum distance from nearest port or safe an-chorage, are given in Table B1. For the various service areanotations the restrictions are related to the zones, areas and sea-sonal periods as defined in the International Convention on

SECTION 2HISTORICAL CLASS NOTATIONS

A. Historical Class Notations

A 100 General101 Historically, a number of ships will retain previous classnotations that will not be covered under the current rules; these

class notations shall remain extant under the rules in force atthe time the class notations were originally assigned. Survey

requirements are those of the latest rules covering the notation.Table D1 gives reference to the last issue of the rules contain-ing the requirements for such notations.

1A2

Last remaining of a series of Maincharacter of Class that startedwith the 1A1 (the highest class)stepwise down to at one time 3C2.

Given in the last few years to ves-sels found meeting the require-ments, but for reason of specialdesign, materials, general condi-tion and/or age, it was considerednecessary to stipulate shorter in-tervals between surveys than

those of main class 1A1.
