B. Mandatory Class Notations
B 100 General
101 All ships being assigned class with the Society will begiven a class notation consisting of a construction symbol, amain character of class, service area restriction notations andmain ship type notations, as applicable.
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

801 NAUTICUS is a notation describing a standard for in-formation and information availability based on access to theSociety’s product model software technology.
802 The NAUTICUS notation will be assigned in combina-tion with additional notations describing specific features re-lating to specific documentation standards. Applicable
notations are given in Table C7 and described in separate sec-tions under Pt.3 and Pt.7.
803 Ships assigned the NAUTICUS notation with additionalnotations will be given the notation NAUTICUS (notation 1,notation 2, etc.).
804 New ships may be ordered with the NAUTICUS (New-building) notation, see Pt.3 Ch.1. Upon delivery from theyard, the NAUTICUS (Newbuilding) notation is retainedand relevant parts of the newbuilding product model are trans-
