ii ABS RULES FOR BUILDING AND CLASSING HIGH-SPEED CRAFT . 2021Notices and General Information
Introduction
1. The year 2021 edition of the Rules for Building and Classing High-Speed Craft consists of the seven
(7) booklets as shown in Table 1. With regard to three booklets, Part 1, Part 2, and Part 7:
a) The purpose of the generic title ABS Rules for Conditions of Classification – High-Speed
Craft (Part 1) is to reflect the expanded contents of PART 1, as a result of including
consolidated requirements for “Classification” applicable to all types of and sizes of high-
speed craft as specified in the Foreword to Part 1. Additional specific requirements are
contained in Chapters 2 and 3 of Part 1.
b) The purpose of the generic title ABS Rules for Materials and Welding of PART 2 is to
emphasize the common applicability of the requirements to ABS-classed vessels, other
marine structures and their associated machinery, and thereby make PART 2 more readily
a common “PART” of various ABS Rules and Guides, as appropriate.
c) The purpose of the generic title ABS Rules for Survey After Construction (Part 7) is to
reflect the expanded contents of PART 7, as a result of including consolidated requirements
for “Surveys After Construction” applicable to all types and sizes of vessels, barges and
specific shipboard arrangements/systems, etc., as specified in Part 7, Chapter 1, Section 1.
2. The numbering system applied in the Rules is shown in Table 2.
3. The primary changes from the 2020 Rules are identified and listed in Table 3. The effective date
of the indicated Rule Changes is 1 January 2021, unless specifically indicated otherwise.
4. The effective date of each technical change since 1993 is shown in parenthesis at the end of the
subsection/paragraph titles within the text of each Part. Unless a particular date and month are
shown, the years in parentheses refer to the following effective dates:
(2000) and after 1 January 2000 (and subsequent years) (1996) 9 May 1996
(1999) 12 May 1999 (1995) 15 May 1995
(1998) 13 May 1998 (1994) 9 May 1994
(1997) 19 May 1997 (1993) 11 May 1993
For certain changes that have a major impact on shipyards, designers and vendors, ABS has
instituted a two-year Rule cycle to give the industry more time to prepare for these changes. The
text of these changes will appear in a box along with the effective date just under the existing Rule
requirement.
5. The listing of CLASSIFICATION SYMBOLS AND NOTATIONS is available from the ABS
website www.eagle.org for download.
