Situation
Class rules permit the use of a harness, with a maximum weight of 4kgs. A competitor uses a harness which weighed 2.5kg when purchased and 3,9 kg after being modified.

Question
Will it qualify as wearing equipment for the purpose of increasing competitor’s weight?

Answer 
It depends. If the primary purpose for modifying the harness is to increase its weight by adding heavyweight elements or components, wearing such equipment will be considered as purposeful increasing of competitor’s weight and therefore it will break rule 50.1(a), even if the harness is within the maximum weight allowed by the class rules.

The same principle applies to wearing an unnecessarily heavy unmodified equipment.
