Class Rule Interpretations

Written by Editor on . Posted in Articles

Question 1 dated June 2012:

Is it allowed to change the bridles on a production kite?

Interpretation:

1.5 defines rigging as "Any equipment attached at one or both ends to spars, sails or other rigging and capable of working in tension only. Includes associated fittings which are not permanently fixed to a hull, spar or spreader." As the bridles are connected to the bridle attachment points they are considered being part of the rigging. In general, everything that is fixed connected with the kite is part of the "sail" and therefore restricted in change, everything that is made to be disconnected without tools from the kite should be considered to be rigging.

We confirm that bridles are considered part of the rigging and therefore can be changed

Question 2 dated September 2012:

The NOR of the 2012 worlds states: "9.2 Special Notice is drawn to the use of leaches and fully functional flag out systems." What does this mean?

Interpretation:

The IKA class rules require in C.3.1 that a "detachable kite leash shall be used" and in C.8.2 that "lines shall have a depowering device". This article in the Notice of Race repeats these requirements: All competitors shall have at all time a "kite leach" and a "depower system". A "fully functional flag out system" is a synonym to a "depowering system".


Question 3 dated September 2012:

Is it allowed to change the footpad to make it more comfortable?

Interpretation:

The introduction of the IKA class rules stats: "THESE CLASS RULES ARE OPEN CLASS RULES WHERE IF IT IS NOT SPECIFICALLY SAY THAT YOU SHALL NOT, THEN YOU MAY ". Changing the footpad does not conflict with C.6.3 so it is allowed.

Important Note: In the near future the IKA open class rules will be replaced by closed class rules. In these closed class rules "WHERE IF IT IS NOT SPECIFICALLY SAY THAT YOU MAY, THEN YOU MUST NOT" . Think twice before you damage your board so it would then have no value any more on the secondhand board market as it is not in compliance with future class rules anymore.



Question 4 dated October 2012:

Can a rider change the inserts for straps, or even add additional inserts for additional straps

Interpretation:

Yes as long as it does not alter the shape or other key characteristics of the board like the weight, which needs to remain in the allowed tolerances.


Question 5 dated October 2012:

Can a rider change the footpads

Interpretation:

Yes as long as it does not alter the shape or other key characteristics of the board like the volume.


 

Question 6 dated May 2013:

I just bought a 2012 board second hand. It has a lot of dings with some minor delamination between core and plies. I was wondering whether it is allowed to remove the damaged section and insert something stronger like more layers of glass fiber or carbon, as long as you maintain the specified weight as per its IKA registration.

Interpretation:

Class Rule c.6.3 (a) specifies:

"(a) Alteration of hull shape, major underside re-fairing or deliberate removal of the finishing coat/s is not permitted unless in the case of the result of local repairs to unintentional damage. The serial number shall remain legible."

Only the above mentioned repairs are allowed. A repair can only use the same material used while the board was manufactured.If carbon was present when the board was manufactured, a similar layer of carbon may be applied, if not, then no carbon must be used.

 


Question 7 dated May 2013:

Is it allowed to put additional plugs for footstraps further to the rail.

Interpretation:

The introduction of the IKA class rules stats: "THESE CLASS RULES ARE OPEN CLASS RULES WHERE IF IT IS NOT SPECIFICALLY SAY THAT YOU SHALL NOT, THEN YOU MAY ". Adding additional plugs for footstraps does not conflict with C.6.3.

Important Note: In the near future the IKA open class rules will be replaced by closed class rules. In these closed class rules "WHERE IF IT IS NOT SPECIFICALLY SAY THAT YOU MAY, THEN YOU MUST NOT" . Think twice before you damage your board so it would then have no value any more on the secondhand board market as it is not in compliance with future class rules anymore.
 

Question 8 dated August 2013:

Are 2011 model kites built in 2012 or 2013 in compliance with the class rules ?

Interpretation:
 
No. Class Rule B.1.2 requires that kites not falling under the registered production equipment scheme are manufactured before 2012.


Question 9 dated August 2013:

Are kites built before 2012 eligible to race at the 2013 kiteracing world championships ?

Interpretation - updated:

Class rule B.1.2 states that 'production kites built before 2012 will be included on the relevant Production Equipment List'. To include such kites on the relevant Production Equipment List, the manufacturer is required to apply to IKA for inclusion and proof 
a) the exact manufacturing date of the kites to be included (if they have been continued to be built in 2012 and later)
b) that the kite is series production (a considerable amount of kites have been produced to exactly the same building specification)
c) that each of such kites is clearly identifiable at an event
Only kites listed on the registration list on the day of registration of the 2013 world championships are class legal. However, sailors using such kites may be required to prove at the event that the kite they are using is identical with the ones listed.


Question 10 dated August 2013:

2011 model kites built in 2012 and 2013 have not been protested in recent major championships. Why are they not eligible to race at the 2013 kiteracing world championships ?

Interpretation:

The fact that kites that were pre-2012 models but manufactured in 2012 or 2013 have not been protested in past competitions by other sailors does not change the interpretation of the class rule. Sailing is a self-policing sport – that a sailor has not been protested in past competitions for using class-illegal kites does not mean that such equipment would be automatically class legal.
 

Question 11 dated September 2013:
 
What are the tolerances in the builder provided measurements that equipment inspectors will accept as manufacturing variances during event post-race measurement ?

Interpretation:
 
Except for the Rockerline, Concave and Vee, Equipment Inspectors normally consider a variation of 3mm as acceptable manufacturing tolerance. However, the final decision if a measurement difference is caused through normal prodcution variation, wear and tear, or other reasons, and the value of the accepted variation is solely within the equipment inspectors descretion, 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".
 
However, any minimum/maximum dimensions stated in the class rules MUST NOT be exceeded even considering acceptable tolerances.

Note: From the 2014 equipment registration cycle onwards stricter tolerances may be applied which will vary from measurement point to measurement point.
