42.3 (b) A boat’s crew may move their bodies to exaggerate the rolling that facilitates steering the boat through a tack or a gybe, provided that, just after the tack or gybe is completed, the boat’s speed is not greater than it would have been in the absence of the tack or gybe. A boat's crew may not hang on the mast or shrouds to promote roll tacking or gybing.
42.3 (c) Except on a beat to windward, when surfing (rapidly accelerating down the leeward side of a wave) or planing is possible, the boat’s crew may pull the sheet and the guy controlling any sail in order to initiate surfing or planing, but only once for each wave or gust of wind.

This includes mast at the deck, spreader sweep, forestay length, height of forestay attachment and other items listed.
My forestay is not longer than the legally allowed length of the class rules (8600 mm between pin eyes).
I (Skipper)............................... certify that my J24 (BOAT NAME)........................... has not been altered from the condition I bought it in and I have not added or subtracted weight from the hull other than in the form of repairs. To the best of my knowledge it complies with the intent of the one design rules of the J24 Class as well as with the above specified rules.
