Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national
standards bodies (ISO member bodies). The work of preparing International Standards is normally
carried out through ISO technical committees. Each member body interested in a subject for which a
technical committee has been established has the right to be represented on that committee.
International organizations, governmental and non-governmental, in liaison with ISO, also take part in
the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all
matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

69, Small craft.
This second edition cancels and replaces the first edition (ISO 15085:2003), of which it constitutes a
major revision. The main changes are:
 New definition of design categories in 3.1;
 Improvement of the list of functions to be performed on or from the working deck in 4.2;
 Improvement of text and drawings on Risk of falling from elevated parts now in 4.5;
 Improvements in Table 4 and 5;
 Addition of requirements for habitable multihulls susceptible to inversion;
 New section 13 on "Crew accommodation deck;
 Improvement of section 14 means of reboarding
 All the strength requirements are grouped in Section 16 (Tables 6 and 7) and Annex A modified
accordingly.
ISO/DIS 15085
Introduction
This International Standard is based on the idea that safety on board of small craft is not obtained through one
simple safety item, but through the conjunction of several items.
It is also based on the knowledge that there is not one single set of safety items per design category and craft
type, but several. In some instances, it therefore provides the boat builder with different options according to
the general use he intends for the craft, within its design category.
The main issue is the definition of the working deck, up to the boat builder, and how people present on the
working deck under normal operation, i.e. under way, shall be protected. This definition is of major
importance. For example, on some craft the working deck is limited to the cockpit, whereas in others it
encompasses the whole deck area.
Access to and use of strong points is a separate issue and is therefore treated differently: this access and use
is needed, but not necessarily when the craft is under way and never at full speed, hence not necessarily on
the working deck.
In this revision, based on 10 years of application background, emphases has been brought to:
 provide means of reboarding directly usable by a person in the water without any exterior help, including
its deploying, where needed;
 checking, where needed, by physical test the fulfilling of the requirements;
 improve the definition of the working deck and the tasks to be performed from it;
 clarification of requirements.

Figure 3 shows a few examples of foot-stops.
8.2 Provision for foot stops
Unless covered by the exceptions listed below, foot-stops shall be installed around the full periphery of the
working deck and located as close as practicable to the outboard edges of the working deck.
Foot-stops are not required on the following:
 capsize-recoverable sailing dinghies;
 on sailing craft in places where people are not intended to walk but only sit when the craft is underway,
such as sailing boat deck edge where the crew hikes;
 the aft limit (perpendicular to the longitudinal axis) of monohull working deck, e.g. top of transoms;
 the aft limit (perpendicular to the longitudinal axis) of the rigid part of multihull working deck;
 front and aft beams (perpendicular to the longitudinal axis) of multihulls.
ISO/DIS 15085
8.3 Minimum foot-stop height and angle
The height of the upper edge of the foot-stop, where fitted above the adjacent working deck level shall be not
less than:
 25 mm for sailing boats of design category C;
 30 mm for sailing boats of design category A and B;
 25 mm for non-sailing boats of design category A and B.
These heights are the smallest distances, measured perpendicularly to the deck, from the highest inner point
of the foot-stop to the highest point of the deck within 100 mm of the foot-stop (see Figure 3.a).
If the edges of the foot-stop have a fillet radius greater than 5 mm, the height of the foot stop shall be
measured between the closest points of these fillets (see Figure 3.b).
To stop the foot from slipping outboard, the angle in the internal face (or of a tangent to it) shall not be more
than 30° from the vertical (see Figure 3.c), except on non-sailing boats using the device described in 8.4 (for
non-sailing boats only).
8.4 Foot-stops made of angled surfaces
Angled surfaces foot-stops are allowed on non-sailing boats of design categories C and D. These surfaces
shall have an inclination of not less than 20° from the horizontal and a height according to 8.3 (see
Figure 3.d).
These angled surfaces shall be slip-resistant.
8.5 Maximum foot-stop clearance between deck and foot stop
If there is a vertical clearance between deck and foot-stop level the open spaces between the deck level and
the bottom of the lowest foot-stopping point shall not be greater than 40 mm (see Figure 3.e).
EXAMPLE Soft or rigid line parallel to the working deck.
8.6 Continuity on the working deck level in way of the foot-stop
In order to guarantee foot-stopping action there shall be no step in the working deck level greater than 15 mm
within 100 mm from the foot-stop (see Figure 3.a).

8.7 Discontinuity in foot-stop rails
Gaps in foot stops and between foot stops and other equipment that can be used as foot stop are allowed in
way of equipment for ease of use or water drainage, but each gap shall with the exceptions below be max
100 mm.
The following cases are exceptions from general requirements above:
 150 mm for mooring cleats on boats where 6 m ≤ L <12 m;
H
 200 mm for mooring cleats on craft where L ≥12 m;
H
 600 mm in areas within pulpits, pushpits and gates where rigid handholds are provided at each side.
This distance being measured along the foot stop general line from the closest part of the foot-stop rail to the
edge of the adjacent fitting
Fittings providing foot-stopping action are considered to be local foot-stops.
EXAMPLE Stanchions, pulpit feet, cleats.

8.8 Strength
The strength of non-integral foot stops, as built and installed, in the plan parallel to the adjacent deck at the
top height of foot stop and in the direction perpendicular to the main direction of the foot stop shall be
according to Table 6
9 Requirements for handholds
9.1 General
The requirements of 9.2 to 9.5 apply to all handholds fitted on the craft.
Guard rails, pulpits and guard lines meeting the requirements of 9.2 to 9.5may be used as a handhold. In such
case 10.1 does not apply.
9.2 General provisions for handholds
On the route along the outer edges of the working deck:
- the maximum horizontal distance between the outer edge of the working deck and handholds shall not
exceed 1 000 mm;
- the maximum horizontal distance between two adjacent handholds shall not exceed 1 500 mm.
9.3 Handhold location in way of side decks
On decks limited by continuous adjacent superstructures up to 1000 mm above deck lever and narrower than
300 mm at 1 000 mm, rigid handholds shall be placed vertically between 450 and 1500 mm above deck level,
and in such a location that it can be reached easily by any person walking on the side deck.
For all the other cases, handholds may be placed at any height.
Figure 4 shows sketches illustrating this requirement.
NOTE This requirement derives from the fact that, on narrow passageways, it is possible only to pass standing, and
therefore, low handholds cannot be reached.
9.4 Handhold Locations on Side deck
On side decks of 300mm width or less with an adjacent superstructure greater than 1000 mm height, Rigid
handholds may be placed at any height.
On side decks of 300mm width or less with an adjacent superstructure up to 1000 mm height, Rigid handholds
should be placed at a minimum height of 450mm.
or
On side decks of 300mm width or less with an adjacent superstructure less than 450 mm height, Rigid
handholds should be placed at the maximum height available.
