SLSA National Surf Craft Manufacturers Registration
Scheme
4.1 Applicant to apply in writing to SLSA, outlining company name,
company principal, address, contact numbers, company
background or profile, and craft to be manufactured (i.e. junior
boards, single skis, etc). An initial (non-refundable) registration
fee of $385 (includes GST) is to accompany the initial
application.
4.2 Subsequent applications, from a registered manufacturer for
registration to manufacture additional types of surf craft, must
be accompanied by a supplementary (non-refundable)
registration fee of $110 (includes GST).
4.3 On receipt of the above application, applicant will be advised in
writing that they will be required to build one craft, of each type
LSV SOP 5.6 – Design & Manufacture of Surfcraft Policy
Page 2
INDEX
5.6:POL:1
EFFECTIVE DATE:
01/10/2004
for which registration is sought, for inspection by the National
Surf Craft Officer (or nominee). The applicant will also be issued
with a copy of current relevant SLSA specifications.
4.4 On advice from the Manufacturer that the craft moulds, (if
appropriate) and appropriate manufactured craft are ready for
inspection, the National Surf Craft Officer (or nominee) will
arrange an inspection to check that the appropriate standards
are met.
4.5 Following the inspection, the manufacturer will be advised in
writing of the outcome of the Application for Registration. The
outcome of the application cannot be assumed until written
confirmation has been received by the manufacturer from
SLSA.
4.6 If successful, an Official Agreement will then be forwarded to
the manufacturer for their signature. Manufacturers cannot
manufacture or sell items purporting to comply with SLSA
specifications until the agreement has been signed and
returned by SLSA.
4.7 If registration is not approved, the Manufacturer will be notified
by the SLSA of the reasons and what action that should be
taken in order that registration may be reconsidered.
4.8 The Manufacturer is then required (if successful) to purchase
from SLSA, Compliance labels ($2.20 each - includes GST) to
be glassed under the surface of all craft (except junior foam
surfboards) manufactured to SLSA specifications.
4.9 Compliance Labels are numbered and stamped with
Manufacturers name. The Manufacturer is also required to date
the label with date of manufacture (month and year). Further,
the manufacturer is required to keep an up-to-date record of all
numbers in sequence, craft type, colour, finished weight, and
name and address of purchaser of each craft.
4.10 Annual re-registration will occur on September 30 each year at
which time an agreement will be forwarded by SLSA to each
manufacturer. A re-registration fee of $110 (non-refundableincludes GST) must accompany the agreement when returned
to SLSA. If the agreement and fee is not received by SLSA in
30 days, the manufacturer’s agreement will become null and
void. Should this occur, the manufacturer must again pay the
$385 (includes GST) initial non-refundable registration fee and
proceed through the original process in becoming a registered

manufacturer if they wish to become a SLSA Registered
Manufacturer.
4.11 Manufacturers applying for annual re-registration may continue
to manufacture craft or sell items while the new agreement is
being signed.
4.12 Penalties for non compliance with SLSA specifications (also see
Agreement):
-
A letter from SLSA will be sent asking the manufacturer
to explain their actions to SLSA in writing.
-
A panel consisting of the SLSA Chief Executive Officer,
Director of Competition and the National Surf Craft
Officer (or their nominee), will adjudicate on each non
compliance matter separately and on its` merits, as
required.
4.13 Manufacturers should be aware that an authorised SLSA
representative shall be entitled at all times during normal
working hours to have necessary access to the premises of a
manufacturer to inspect craft, moulds if appropriate, the
manufacturing process and the Craft Manufacturing Register.
This is necessary to ensure that craft, which have been
manufactured or are in the course of manufacture comply with
the conditions and specifications as outlined in this document
and SLSA specifications for manufacturing of surf craft.
4.14 Manufacturers will be placed on the SLSA national mailing list
and will receive club mail in order to keep them abreast of
current matters within SLSA.
Note: i)
Craft built by Registered Manufacturers and not bearing
the “SLSA Approved” sticker will not be permitted to
participate in SLSA competitions/activity, with the exception of
Junior (Nipper) Foam Surf Boards which must comply to
Specification No. 6 of this Bulletin but may be subject to safety
checks and compliance at all SLSA activities.
INDEX
5.6:POL:1
ii)
Craft not built by Registered Manufacturers and not
bearing the “SLSA Approved” sticker will need to be
scrutineered by a Surf Craft Inspector nominated by the
National Surf Craft Officer with the manufacturer paying a fee
as advised by the SLSA.

iii)
The SLSA at all levels through carnival/activity
organisers, reserves the right to scrutineer any or all
equipment at any said activity.
Purpose of the Specification
These specifications refer to Craft used in SLSA competition/rescue
and will be used by SLSA Officials to determine the eligibility, or
otherwise, of competitor's craft.
Any competitor, or club, who attempts to win a race by any other than
honourable means may be disqualified. This includes the use of Craft
not meeting the requirements of the appropriate SLSA specifications.
Manufacturers have an obligation to SLSA to ensure that all craft
manufactured comply with the appropriate specifications.
Clubs/competitors have a responsibility to ensure craft remain within
specification.
When a change in basic design is contemplated, manufacturers shall
first seek the advice of the National Surf Craft Officer or his/her
nominee as assigned by Surf Life Saving Australia.

mechanism.
Floatation: Double Skis shall contain a minimum floatation in
the form of foam or other approved material to provide
buoyancy of 40kg mass.
Note I: Isolite foam provides buoyancy of 10kg for each 0.01
cubic metre.
9.8
Design: Minimum measurements along the hull from a flat
horizontal surface required are:
(i)
75mm at stern to underside, which will be the general
continued curvature line of the hull;
(ii)
300mm at bow along true line of gunwale (deflectors
are not considered to be a part of a true line of the
gunwale and should not be included in the
measurement);

(iii)
At 600mm in from stern, a clearance of 50mm;
(iv)
At 100mm in from bow, a clearance of 200mm;
(v)
At 400mm in from bow, a clearance of 75 mm;

A double ski less than the maximum length of 7.32
metres must still comply to the measurements from bow
and stern - for the curvature check.
Measuring: The ski must sit on SLSA’s standard jig (see figure
5) and touch or clear all jig measurements, keeping within the
overall length. For skis less than the minimum length the jig
must be adjusted to the length of the ski.
There must be no reverse curvature of the bottom of the ski
from the bow to the line of SLSA's standard jig.
Note I: For details of procedures of measurement refer to
appropriate Bulletins issued by Australian Council on
Scrutineering of Surf Craft.
9.10 As a safety precaution, minimum profile of hull / deck at tail
and bow (where removable deflector is used) of skis in either
plan or side elevation shall be 25mm. Minimum radii in other
direction to be 3mm.
Further minimum radii of V bow to be 3mm.
Note I: Projection of overlapping deck past the hull at tail (and
bow) to not exceed 5mm.
Note II: If a deck overlap is less than 25mm deep at the join
the 25mm radius must extend to 25 mm depth minimum.
9.11 Surf Ski Paddles. Currently no specification for paddles exist,
however all paddles must be free of sharp or jagged edges
which may cause injury. Metal tipped paddles are not
permitted to be used.
