The JC strap is not key on the aero, but in the very light helps keep the light boom forward. If you used it as an effective return spring for 'pumping' then I would assume it may fall foul of rule 52, but the whole question of pumping is a moot point. The Finn has specific rules which I believe permit one pump per wave and Sir Ben's Olympic coverage showed that to its max. I don't know what the class rule for the solo says, but I have certainly observed plenty of pumping! The aero can certainly be pumped along quite impressively in light winds as it is itself so light, but there is no set in stone view as what is acceptable.

Once the wind is light, the Finn pumping switches off. I really hope the Aero CA has a very strict view on pumping, given the difference it will make on such a light boat.

There is no variance in the ca rules so rule 52 and rule 42 apply to the aero I.e no pumping or ouching. ISAF rule 42 allows one pump per wave only IF that is to induce planning. So the Finn is basically just using rule 42 correctly.

What is never going to be entirely clear for any dinghy is where the line is in regards to rule 42 and usually young bendy people being 'kinetic' in a boat. As I understand it the rules basically say you can't except to induce a roll tack.

The Finns do go beyond normal R 42, they and the 470s have a class rule that if the wind is above 10knots a signal is made before the race that switches off R42.2 completely so unlimited pumping and ooching is allowed.

C.1.1 RULES (1) RRS 42.3 is changed by adding: The Race Committee may signal in accordance with RRS Appendix P5 that pumping, rocking and ooching are permitted after the starting signal, except when the boat’s proper course is close-hauled or above. This changes rules 42.2(a), 42.2(b) and 42.2(c). (2) The Finn Class recommends that race committees apply 
Rule C.1.1 (1) in winds of 10 knots and above, measured at deck level on a race committee boat at the windward mark. See also A.7.2.  

So in light winds normal rules apply, is strong winds all bets are off!

Class to class, what is acceptable varies, so I was suggesting that the CA (ie the regular sailors) set the tone and ensure it is pumping free. Suspect this is a Pipedream.

And yet the RRS don't appear to define what planing is.

Who really knows what planing is anyway - its already been debated to death on here. i think we all know when we are 'surfing' and that is probably what rule 42 encourages through a pump per wave definition. The aero is no different to any other dinghy in application of the sailing rules. Same applies to blaze, solo, supernova, dzero, phantom , solution, streaker etc etc..

How can you have a rule that allows pumping to facilitate planing if you can't define what planing is? Protest city Arizona.

Well it applies to your class as well so how do you define it? 

Its not a class thing its the ISAF rules of racing.

I didn't mean to imply it was an aero problem. Maybe better suited to one of the rules posts.
