The following pages will provide information for builders wishing to register a new TT:R hull model for use in IKA TwinTip:Racing class events.
IKA Approved Series Production boards and kites is mass produced kiteboarding equipment made in a series production run of at least 75 pieces per model/size.Each piece of equipment shall be produced using the same manufacturing specification and materials and shall be within tightest production tolerances.The brand guarantees a minimum capacity to build 25 pieces per equipment/model/size per month after the initial production run.The brand guarantees that world wide distribution is available and that equipment will be delivered to customers on a first come-first served basis if not otherwise agreed with IKA or World Sailing.
Equipment will be eligible to compete 3 months after registration is completed (75 pieces built, successful factory inspection by class measurer, registration fees paid, and availability world wide).
All equipment is registered as "model". The IKA fees apply regardless of the number of equipment produced and are used for administering the scheme.The fee (500 EUR plus VAT where applicable) is payable per model and size.
The manufacturer agrees to cover reasonable expenses (travel, accommodation, subsistance) for an initial factory inspection by a class measurer before equipment becomes eligible to compete as well as an annual factory inspection by a class measurer.
IKA will enter the equipment on the relevant list of IKA Approved Series Production Equipment only when the registration procedure has been completed to the IKAs and WORLD SAILINGs satisfaction, and all invoices and costs settled.
The final registration deadline for new equipment is 3 months before the first qualification event to the next Youth Olympic Games.
The "IKA Registered Series Production Equipment" logo shall be attached or printed to all equipment.All equipment is required to carry a unique manufacturers serial number on every equipment part.
Instructions on Plaque usage:
The plaque layout may be requested in electronic form (vector format) from the IKA
All measurements submitted shall be taken as the average of at least 10 pieces of equipment.TT:R HULL STIFFNESSThe Registration Form refers to the 'stiffness' of the hull measured in accordance with the WORLD SAILING measurement procedure. This procedure is as follows:1. The hull shall be supported on the underside perpendicular to the outermost heel-side fin-screw holes from each end of the hull.2. The deflection (d) of the hull shall be measured on the under body of the hull on the centreline at the mid-section with 10kg of weight placed on the upper surface of the hull on an area of not more than 100sqcm with its centre of gravity immediately above the measurement point3. The 'stiffness' of the hull shall be determined from the equationStiffness = d x 1000 (d in mm)NotesThe two supports should be constructed of aluminum or other metal.
The graphic below shows the key measurement points.All measurements are taken along the rocker.Measurements A, B, C are taken from the CENTER of a screw-hole or from the OUTERMOST/INNERMOST point of a box.Measurements D, E, F are taken from the outermost point of the rail, where the red line meets the rail.Measurement G, H, I, J are taken from the outermost point of the rail. The yellow lines go through the CENTER of screw-holes and CENTER of boxes.Measurements K, L, M are taken as maximum thickness at the red lines
The following tolerances are considered to be reasonable by the class measurers.Tolerances are intended to allow for necessary manufacturing tolerances and shall not be used to alter the design.When measuring hulls registered after 01.01.2013, equipment inspectors will consider the following tolerances as acceptable, however any measurement must retain within the minimum and maximum dimensions stated elsewhere in the class rules:
The final decision if a measurement difference is caused through normal production variation, wear and tear, or other reasons, and the value of the accepted variation is solely within the equipment inspectors discretion, and he may apply larger or smaller tolerances when justified following the principle that "any equipment is built to the highest possible degree of uniformity in every performance related respect".
Complete a registration for every size / variation.
All measurements for the hull shall be taken as shown in the diagrams
