Full title and description

AS 4132.1-1993 — Boat and ship design and construction, Part 1: Design loadings. Specifies the loads to be used in the determination of scantling sizes for vessels not exceeding 35 m in length; includes guidance for multi-hull vessels and excludes novel vessel types and special operating conditions.

Abstract

This Standard sets out the design loadings (static and operational) applicable when determining structural scantlings for small craft and vessels up to 35 m hull length. It gives values and methods for longitudinal and transverse loading, local pressures and environmental actions (waves, wind, slamming, deck loads), and special provisions for multi‑hull craft. It does not cover novel configurations (for example hydrofoils or SWATH) or exceptional operations such as docking and towage, nor does it itself include factors of safety for material or workmanship uncertainties.

Scope

Applies to the design loadings used in calculating scantlings for vessels not exceeding 35 m in length. Includes multi‑hull considerations but excludes hydrofoils, small‑waterplane‑area twin‑hull (SWATH) vessels and other unusual configurations. The Standard is intended for normal service in unprotected waters and for handling consistent with good seamanship; it excludes special operating procedures (e.g. docking, towage) and does not prescribe additional safety factors for material or workmanship uncertainty.

Key topics and requirements

• Definition of design load cases for small vessels (operational and environmental loads).
• Longitudinal bending moments and distribution for hull girder scantling calculations.
• Transverse and local loads (deck, machinery, fittings) and their application to local scantlings.
• Wave, wind and slamming load considerations appropriate to vessels ≤35 m.
• Special requirements and adjustments for multi‑hull craft.
• Exclusions: novel vessel types (hydrofoils, SWATH), docking/tugging/towing load cases and explicit material safety factors.

Typical use and users

Used by naval architects, small craft designers, boatbuilders, classification societies, surveyors and regulatory bodies when establishing structural scantlings and checking designs for vessels up to 35 m. Also used as a reference in procurement, certification and educational/training material for small vessel structural design.

FAQ

Q: What is this standard?

A: AS 4132.1-1993 is an Australian Standard titled "Boat and ship design and construction — Part 1: Design loadings" that defines the load cases and magnitudes used to determine structural scantlings for vessels up to 35 m in length.

Q: What does it cover?

A: It covers operational and environmental design loadings (longitudinal, transverse and local loads, plus wind and wave actions) for normal service afloat and includes special considerations for multi‑hull vessels. It excludes novel hull forms (e.g. hydrofoils, SWATH) and special operations such as docking or towage.

Q: Who typically uses it?

A: Naval architects, small craft designers, boatbuilders, surveyors, classification societies and regulators use it when designing, checking or certifying the structural scantlings of vessels up to 35 m.

Q: Is it current or superseded?

A: AS 4132.1-1993 was withdrawn on 6 June 2019. It is no longer an active sale publication; users should check for any more recent standards or national/regulatory requirements that have replaced or superseded its content.

Q: Is it part of a series?

A: Yes — it is Part 1 of the AS 4132 series. Companion parts include AS 4132.2-1993 (Aluminium construction) and AS 4132.3-1993 (Fibre‑reinforced plastics construction).
