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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this part of ISO 6185 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 6185-1 was prepared by Technical Committee ISO/TC 188, Small craft.
ISO 6185-1, together with ISO 6185-2 and ISO 6185-3, cancel and replace ISO 6185:1982. They differ significantly
from ISO 6185:1982 as they cover boats made from unsupported materials, whereas the latter only covered boats
made from reinforced materials.
ISO 6185 consists of the following parts, under the general title Inflatable boats:
� Part 1: Boats with a maximum motor power rating of 4,5 kW
� Part 2: Boats with a maximum motor power rating of 4,5 kW to 15 kW inclusive
� Part 3: Boats with a maximum motor power rating of 15 kW and greater
Annexes A and B form a normative part of this part of ISO 6185. Annexes C, D and E are for information only.
ISO 6185-1:2001(E)

Visual inspection during and following in-water performance tests described in 7.2.
5.7 Hull drainage
If the boat is fitted with a transom, it shall be equipped with at least one drainplug or one bailing system.
For RIBs fitted with an integral closed hull/deck assembly which is not filled with closed-cell foam or equivalent, a
facility shall be provided for draining the lower part of the hull.
ISO 6185-1:2001(E)
5.8 Rudder steering system (where offered as standard or optional equipment)
5.8.1 Strength of the assembly
5.8.1.1 Requirement
No fracture or other damage shall occur following 500 movements of the rudder-blade over an angle of 60°.
5.8.1.2 Test method
Each movement (cycle) shall be carried out within 1 s and shall include the complete steering gear. The rudder-
blade shall be submerged in its service position.
5.8.2 Rudder-blade
5.8.2.1 Requirement
The rudder-blade shall be capable of being hoisted to the level of the boat bottom and of being fixed in its working
position without the use of tools.
5.8.2.2 Test method
Function test followed by visual inspection.
5.9 Remote steering system (Type II only where offered as standard or optional equipment)
Any remote steering system shall conform to the requirements of ISO 15652 and ISO 9775.
There shall be no damage or malfunction to either the system or to any related attachments to the boat when
tested in accordance with clause 7.
5.10 Motor-securing line attachment (Type II only)
A means for attaching a motor-securing line shall be provided at an appropriate position.
5.11 Towing device (all types)
All craft shall have, at their bow, a towing device suitable for securing a towline. See 7.3 for strength test.
5.12 Seating and attachment systems (where offered as standard or optional equipment)
There shall be no damage or malfunction to either the seating or to any related attachment systems when tested in
accordance with clause 7.
6 Safety requirements of the completed boat
6.1 Maximum permissible number of persons
The maximum permissible number of persons n carried shall be calculated for each boat type as follows:
A
i
Type I: n �
0,3
where A is the inboard area, in square metres.
i

ISO 6185-1:2001(E)
l
i
Types II, IV: n��1
0,38
where l is the inboard length, in metres.
i
Type III: See annex A.
Under no circumstances shall the value n, expressed in body mass, exceed the maximum load capacity (see 6.4).
The value n is reduced by one person if either the maximum motor power rating exceeds 3 kW (4 hp) or if a sailkit
is mounted.
For Type I, II and IV boats, the value n shall always be rounded down to the nearest integer but, if the first decimal
place is greater than 5, a child may be added or, if greater than 7, an adult may be added.
For calculations, the body mass of a child is defined as 37,5 kg and the body mass of an adult as 75 kg.
The data displayed on the builder’s plate(s), see clause 8 e), shall include at least one adult and not more than one
child.
6.2 Maximum motor power
This is applicable to Type II boats only.
� For boats without a transom: P =0,8F(d)
max
� For boats with a transom: P =1,2F(d)
max
where
P is the maximum motor power rating, in kilowatts, determined in accordance with ISO 8665;
max
F(d) is the dimensional factor = l � b
where
l is the overall length of the boat, in metres, from the bow to the extremity of the rear float
(excluding handholds or other fittings);
b is the overall beam of the boat, in metres (excluding handholds or other fittings).
6.3 Static stability of the boat
6.3.1 Requirement
The boat equipped with the manufacturer's maximum rated motor(s) (see 6.2) shall not capsize when tested as
described in 6.3.2.
6.3.2 Test methods
Carry out the test with the motor(s) fitted but without a fuel tank, battery or sailkit. Evenly distribute the test load
over the test loading area of the boat as shown in Figure 2.
The total test load m , in kilograms, shall be calculated using the following formula:
t
m =(0,67 � n � 75) + (0,67 � 37,5) for a child, if applicable
t
ISO 6185-1:2001(E)
where
n is the maximum permissible number of adults determined by the manufacturer (see 6.1), i.e. 75 kg for
each permissible adult and 37,5 kg for a child, if applicable.
NOTE The dimensions for a 37,5 kg steel test weight are given in Figure 2.
