That would seem like a far too logical and helpful idea.
I would suggest that the fact it hasn't been adopted is to provide for a 'you make your bed and lie in it' scenario at the beginning of the series.
The racing was cancelled today because the rules state there has to be a minimum of 6.5knts of wind constant.
Yep I understand that, my suggestion is simply an extension of the ability to change sails from an approved and measured suit of sails. This is no different. There have been lots of adjustments to the racing rules to try and keep the racing close, eg penalties for racing infringements are very low, ie drop back 50m

Maybe LR have made the right call on foils, placing bets that they are match fit thus likely to win more starts, and if they do all they have to do then is not have a major wobble on the 6 legs to the finish because ETNZ might be a bit quicker on any particular wind conditions but not enough to swap the lead with decent covering. Then there are days where the wind favours LR, even more so in the pre start trying not to fall off the foils.

Dunno, too complicated for me.

As an unbiassed observer, i feel that if a lead greater than 1km occurs while one boat is off its foils then the race should be abandoned.

It will be a great pity if the series is decided by one unrepresentative race especially where both boats struggled because of very variable winds across the course.

No, each team takes its chances and sails the best race it can. Fluky winds have always been a part of sailing.

Wow, races 6&7 were amazing from an independent point of view - proper match racing, with lead changes and then the drama of race 7

Bring it on tomorrow - I think tomorrow will be the decider!!

ETNZ seem to have upped their game on tacks. There's a theory going round that they have discovered how to roll tack, basically by easing the angle of the leeward sponson and wing, thus inducing roll to leeward, centre of effort from sail plan now outside the pivot point and quicker turn through the tack. Data on angles and ground made up to back the theory too. Though what I saw was a bit hit and miss.

Roll tacking one of those up on the foils at 30 knots plus, not for the faint hearted. Amazing to see the skills and the amount of data that is available.

Roll tacking a foiling monohull. That would be incredibly brave. And ingenious.

Agreed but hopefully not and we’ll get a few more days of racing.

Mozzy Sails on YT has an analysis of it. They tack on one foil rather than two, it creates less drag and induces a bit of heel, thus the ‘roll tack’.

Is that like oversteer? I haven't looked it up but assume that would be the effect

Not really. It is more about the boat leaning over towards the outside of the turn, then the sail experiences more pressure as it snaps back upright again. It’s a thing in dinghy sailing, not so much in bigger boats.

Must admit there's been a couple of mark roundings by ETNZ involving a tack-bear away-gybe where the time on two legs has been so short that have been sheer poetry and extremely brave.

Yesterday weren't there were some complaints from LR followers whining about losing to a faster boat and also whinging about the rate of closing the gap when LR were off the foils. Presumably they weren't whinging earlier when ETNZ had fallen off and LR were off into the distance. Didn't have to deliberately sail off race course to get back on foils either. Bah.

Still today, proper racing.

I said proper match racing yesterday, but today is PROPER match racing.

LR gambled on the wind shift and unfortunately it did not pay off.

exciting for tomorrow
