Small craft - Hull construction and scantlings - Part 7: Determination of loads for multihulls and of their local scantlings using ISO 12215-5 (ISO 12215-7:2020)
EN ISO 12215-7:2020

This document defines the dimensions, local design pressures and global loads acting on multihull
craft with a hull length (LH) or load line length of up to 24 m (see Note). It considers all parts of the
craft that are assumed watertight or weathertight when assessing stability, freeboard and buoyancy in
accordance with ISO 12217 (all parts). Scantlings corresponding to the local design pressures are then
assessed using ISO 12215-5.
NOTE The load line length is defined in the OMI "International Load Lines Convention 1966/2005", it can
be smaller than LH for craft with overhangs. This length also sets up at 24 m the lower limit of several IMO
conventions.
This document is applicable to multihulls built from the same materials as in ISO 12215-5, in intact
condition, and of the two following types:
— recreational craft, including recreational charter vessels;
— commercial craft and workboats.
It is not applicable to multihull racing craft designed only for professional racing.
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 in conjunction with
ISO 12215-8 for rudders, ISO 12215-9 for appendages of sailing craft and ISO 12215-10 for rig loads and
rig attachment in sailing craft. ISO 12215-6 can be used for additional details.
Throughout this document, unless otherwise specified, dimensions are in (m), areas in (m2), masses
in (kg), forces in (N), moments in (Nm), Pressures in (kN/m2) (1 kN/m2 = 1 kPa), stresses and elastic
modulus in (N/mm2) (1 N/mm2 = 1 MPa).

Small craft - Hull construction and scantlings - Part 10: Rig loads and rig attachment in sailing craft (ISO 12215-10:2020)
EN ISO 12215-10:2020

This document specifies methods for the determination of:
— the design loads and design stresses on rig elements; and
— the loads and scantlings of rig attachments and mast steps/pillars;
on monohull and multihulls sailing craft.
It also gives, in Annexes, "established practices" for the assessment of mast steps/pillars or chainplates
NOTE 1 Other engineering methods can be used provided the design loads and design stresses are used.
This document is applicable to craft with a hull length LH up to 24 m but it can also be applied to craft up
to 24 m load line length.
NOTE 2 The load line length is defined in the OMI "International Load Lines Convention 1966/2005", it is
smaller than LH. This length also sets up, at 24 m, the lower limit of several IMO conventions.
Scantlings derived from this document are primarily intended to apply to recreational craft, including
charter vessels.
This document is not applicable to racing craft designed only for professional racing.
This document only considers the loads exerted when sailing. Any loads that may result from other
situations are not considered in this document.
Throughout this document, and unless otherwise specified, dimensions are in (m), areas in (m2), masses
in (kg), forces in (N), moments in (N m), stresses and elastic modulus in N/mm2 (1 N / mm2 = 1 Mpa).
Unless otherwise stated, the craft is assessed in fully loaded ready for use condition.

Small craft - Hull construction and scantlings - Part 5: Design pressures for monohulls, design stresses, scantlings determination (ISO 12215-5:2019)
EN ISO 12215-5:2019

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 NOTE 1) of up to 24 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 ISO 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 24 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 NOTE 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 Clause 12 and Annex J.
It is not applicable to racing craft designed only for professional racing.
NOTE 2 Local pressures and stresses for multihulls are given in ISO 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 ISO 12215-8 for
rudders, ISO 12215-9 for appendages and ISO 12215-10 for 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 6 m (see Annex 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 (1 kN/m2 = 1 kPa), stresses and elastic
modulus in N/mm2 (1 N/mm2 = 1 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.

Small craft - Hull construction and scantlings - Part 1: Materials: Thermosetting resins, glass-fibre reinforcement, reference laminate (ISO 12215-1:2000)
EN ISO 12215-1:2018

This part of ISO 12215 is applicable to thermosetting resins and glass-fibre reinforcement used in the construction of
small craft with a length of the hull of up to , in accordance with ISO 8666. This part of ISO 12215 specifies
the minimum requirements for material properties of glass reinforcement and resin matrix and the reference laminate
made thereof.
This part of ISO 12215 may be applicable to materials other than those specified, provided that the minimum requirements
and properties of the reference laminate are met.
NOTE The underlying reason for preparing this International Standard is to harmonize existing standards and recommended
practices for loads on the hull and the dimensioning of small craft because they differ too considerably and thus limit general
worldwide acceptability of boats.

This part of ISO 12215 specifies requirements for core materials for structural use and materials that are embedded
in sandwich construction. It is applicable to small craft with a hull length (LH) according to ISO 8666 of up to 24 m.
NOTE The underlying reason for preparing this part of ISO 12215 is that sandwich structures of small craft require careful
selection of core materials from a multitude of choices, and that the manufacturing has to follow certain procedures to achieve
the intended long-term durability under the expected loads and environmental conditions.

This part of ISO 12215 concerns structural details and structural components not explicitly included in
ISO 12215-5, ISO 12215-7, ISO 12215-8 and ISO 12215-9. It applies to monohull and multihull small craft
constructed from fibre reinforced plastics (FRP), aluminium or steel alloys, wood or other suitable boat
building material, with a hull length, in accordance with ISO 8666, of up to 24 m.
This part of ISO 12215 fulfils two functions. Firstly, it supports ISO 12215-5 by providing further explanations
and calculation procedures and formulae. Secondly, it gives a number of examples of arrangements and
structural details which illustrate principles of good practice. These principles provide a standard against which
alternative arrangements and structural details can be benchmarked, using the equivalence criteria specified
