INTRODUCTIONSKUD 18 hulls, hull appendages, rigs and sails shall only be manufactured by builders
licensed by Hansa Sailing Systems Pty Ltd in the class rules referred to as licensed
manufacturers. Equipment is required to comply with the SKUD 18 Building
Specification.
SKUD 18 hulls, hull appendages, rigs and sails may, after having left the manufacturer,
only be altered to the extent permitted in Section C of the class rules.
Rules regulating the use of equipment during a race are contained in Section C of theseclass rules, in ERS Part I and in the Racing Rules of Sailing.
The objective of these Class Rules is to keep the absolute one design aspect of the Classby ensuring that all boats are as identical as possible in terms of construction
procedures, shape of hull and appendages, weight and weight distribution, equipment,
sail plan and performanceThis introduction only provides an informal background and the SKUD 18 Class Rules
proper begin on the next page.

RULES
(a) The ERS Part I – Use of Equipment shall apply.
(b) RRS 50.4 Headsails shall not apply.
(c) RRS 52 is amended so that to compensate for a sailors disability, a boat’s

C.2

CREW

C.2.1

LIMITATIONS(a) The crew of a SKUD 18.2 shall consist of two (2) persons.
(b) The crew of a SKUD 18.3 shall consist of three (3) persons.

in contact with their seat’s sitting surface at all times while racing.
(e) If one centreline seat only is fitted, one crew may use a trapeze if the
Notice of Race specifies J1 or J2 configurations. This changes RRS 49.1.

C.3

PERSONAL EQUIPMENT

C.3.1

MANDATORY(a) The boat shall be equipped with personal buoyancy for each crew member
to the minimum standard ISO 12402-4 (CE 50 Newtons), or USCG Type III, or

Seating may be produced by any manufacturer. If fitted, seating shall meet thefollowing specifications:a) All seating shall be mechanically attached to the hull on the centreline via theprovided tracks in a manner to avoid separation whilst under sail. Theirlongitudinal position is optional but shall be fixed longitudinally during racing.
b) Every seat shall have restraints which shall secure the crew within the seating
surface of their seat (as defined in C.3.3.c) at all times during racing. Every
restraint shall have a quick release mechanism which shall be clearly visible forfast assistance on the water.
c) The seating surface shall not exceed 500mm athwartships or 450mm
longitudinally. Longitudinal dimension is measured from the centre of the seatback at the sitting surface to the most forward sitting surface (i.e. to the steering
joystick if mounted in centre of seat). Leg rests are not part of the seat length,
but can be integral to the seating. The seating surface is defined as the surface
upon which the sailor sits and shall include any cushion or padding.
d) A canting mechanism on the seat is permitted, limited to a maximum totalrotation of +/- 25 degrees from vertical. Safety mechanisms to prevent
uncontrolled motion of the seat shall be demonstrated. The intent of thisprovision is to allow for the comfort and wellbeing of a sailor and not to projectweight to windward.
Canting seats shall pivot around a single point which shall be along the hullcentreline, and not less than 150mm above the cockpit floor.
e) All seating shall have a backrest and sides with a minimum height above thesitting surface of 125mm. Backrest and sides shall be of rigid construction
extend for a minimum of 100% of the seat width and length respectively,
measured at the seating surface. The sides of canting seats shall be within 5
degrees of vertical. The sides of non-canting seats shall be within 25 degrees ofvertical. Sitting on the legrest, backrest or sides is not permitted at any time
during racing. The intent of this provision is to allow for the comfort andwellbeing of a sailor and not to project weight to windward.
Where commercially available seats are installed to meet a sailor’s individual
disability, such as ‘go-kart’ seats or similar, the requirements of this sub-clausemay be waived subject to approval of the SKUD 18 Technical Committee.
f) Maximum seat height from the cockpit floor to the seating surface shall not
exceed 450mm. Upon application to the SKUD 18 Technical Committee, anincreased seat height may be allowed for individual sailors of short stature.
