APPROVED SKIFFS
The Class is the final interpreter and arbitrator of this rule.
PART 1
Approved skiffs shall comply with the following requirements in order to be first registered.
a) Length:
Length to be measured between two vertical marks positioned at each end of the skiff. These marks to reflect comments under (i) & (ii) below.
The horizontal distance between these verticals is not to exceed 3.700 m and must not be less than 3.650 m. No fittings, whether fixed or removable may extend the overall ‘waterline’ length beyond 3.700m. The skiff must be set up on a floor in such a way that the height of spring or keel rocker is equidistant from the floor at each end. (See Fig.1) All fittings and spars extending the overall length must be removable for measuring except for:
(i) integrated bow structures that may extend the ‘out of water’ length by 700mm. The structure can extend below the top edge of the gunwale 100mm with a width of 370mm. Web members may extend below this to within 100mm height of the forefoot with maximum total cross-sectional dimensions of 80mm by 15mm width. (see fig 2).
(ii) integrated stern outrigger structures that may extend the ‘out of water’ length by 550mm. Buoyant compartments, included within these structures to have a maximum width of 600mm.
b) Planking:
The maximum thickness of the planking below the gunwales shall be 25mm. (See Fig. 3)
c) Beam:
(i) Maximum Beam Overall 1.800 m
INTERPRETATION:The maximum beam overall shall be measured from the outside edge of one gunwale to the outside edge of the other gunwale at the widest point and at right angles to the centreline of the skiff.
d) Spare:
e) Trapezing Extensions:
Trapezes on skiffs are permitted. No extension, device or fitting that projects beyond the maximum beam overall measurements will be permitted if such extension, device or fitting enables the crew to obtain additional leverage from their trapeze.
f) Weight:
The minimum weight shall be 45kg when dry. The minimum weight shall include all fittings except spinnaker pole,rudder box, boom, centreboard, rudder, mast, sails, jib main and spinnaker sheets.
g) Buoyancy:
Buoyancy must be contained within the buoyancy measurements given below.
(i) The skiff must have a minimum of two sealed compartments of adequate combined volume to support a rigged boat and two crew when capsized.
(ii) The forward buoyancy compartment must be a minimum 1.100m in length and must not exceed 2.600 m in length measured from the outside of the stem to the aft edge of the buoyancy compartment. Alternatively the skiff must have one watertight bulkhead down the entire length of the centreline.
(iii) The Vertical distance between the top edge of the gunwales and the top of any buoyancy compartment must be greater than 300mm between the front edge of the centreboard case and 700mm forward of the transom measured on the centreline.
INTERPRETATION: Planking, gunwales and other structures as defined by these rules will not be classed as buoyancy. The length of bouyancy will be measured horizontally parallel to the centreline.
h) Spare:
i) Hull form:
The skiff have the deepest part of its hull on the centreline.
j) Appendages:
Hydrofoils, sponsons or other devices designed to provide vertical lift are not permitted. The maximum thickness of any foil shall be 100mm, measured at right angles to the centreline of the skiff.
k)Spare:
l) Spare:
m) Name:
The registered name of the skiff must be placed externally on the transom in no less than 50mm high durable letter. No other writing but the registered name and the skiffs club may be placed on the transom. Writings and logos on other parts of the hull are unrestricted.
n) Registered design:
Each skiff must have a distinguishing sponsors name or colored design attached to both sides of each mainsail it uses. No two skiffs shall have the same name or registered design. Such a name or registered design shall measure at least 600mm in length in any direction.
o) Sails and spars:
Sail areas, designs and configuration is completely unrestricted.
PART 2
A skiff, including hull and spars, may not be altered or changed after initial registration so as to become illegal under the measurement rules for new boats in force at the time of alteration. Otherwise, a skiff will be an approved skiff and may be re-registered provided that it complied
with the measurement rules in force when it was first registered.
PART 3
A skiff may not sail in an Association, interclub or Inter-Dominion race unless:-
(i) It is registered
(ii) It displays a registered name and design,
(iii) It is sailed by at least two persons
(iv) It does not carry electronic equipment
(v) All skiffs using a "fixed pole" system must have an Association Approved "safety orange" stripe at least 100mm long affixed to the pole within 350mm of the outward end.
(vi) Arrangements have been made for Marine Third Party Liability Insurance and acknowledgment of it has been made on the Association registration form.
