This document defines the dimensions, design local pressures, mechanical properties and design stresses for the scantlings determination of monohull small craft with a hull length (LH) or a load line length (see NOTEá 1) of up to 24á m. It considers all parts of the craft that are assumed to be watertight or weathertight when assessing stability, freeboard and buoyancy in accordance with ISOá 12217.

NOTE 1

The load line length is defined in the IMO "International Load Lines Convention 1966/2005", it can be larger than LH for craft with overhangs. This length also sets up at 24á m the lower limit of several IMO conventions.

The main core of this document determines the local design pressures and stresses for monohulls and details the possible scantlings methods derived from these pressures and stresses, both for monohulls and multihulls (see NOTEá 2). The assessment process requires, where relevant, the application of Annexes.

This document is applicable to small craft, in intact condition, of the two following types:

  • recreational craft, including recreational charter vessels;

  • small commercial craft and workboats, see Clauseá 12 and Annexá J.

It is not applicable to racing craft designed only for professional racing.

NOTE 2

Local pressures and stresses for multihulls are given in ISOá  12215-7 .

This document is applicable to the structures supporting windows, portlights, hatches, deadlights, and doors.

For the complete scantlings of the craft, this document is intended to be used with ISOá 12215-8for rudders, ISOá 12215-9for appendages and ISOá 12215-10for rig loads and rig attachments.

This document covers small craft built from the following materials:

  • fibre-reinforced plastics, either in single skin or sandwich construction;

  • aluminium or steel alloys;

  • glued wood or plywood (single skin or sandwich), excluding traditional wood construction;

  • non-reinforced plastics for craft with a hull length less than 6á m (see Annexá D).

Throughout this document, unless otherwise specified, dimensions are in (m), areas in (m2), masses in (kg), forces in (N), moments in (N.m), pressures in kN/m2(1á kN/m2á =á 1Ãâ₠¬Å¡Ãƒâ€š ÃƒÆ’¡Ãƒâ€š kPa), stresses and elastic modulus in N/mm2(1á N/mm2á =á 1Ãâ₠¬Å¡Ãƒâ€š Mpa). Max(a;b;c) means that the required value is the maximum of a, b, and c; and min(d;e;f) means that the required value is the minimum of d, e, and f.
