Congratulations to the Paradox team, thanks SL for posting video, very convincing stability and no significant pitching, for sure it will add to the rig efficiency.

I am a bit surprised by the figure 20knts boat speed for 12 knts TWS ?

Could you please disclose the TW Angle ?

Sometimes I wonder if it would deserve to create a thread which would primarily gather infos to establish a proxy of A-Cat polar curves.

Thanks AClassUSA230 for posting such datas on a regular basis, so far you are already the main contributor of the polar project.

Hold on Mates you get it

Congratulations again

Cheers Mate

So since the  thread is back on its core topic, a pre-requisite would be to make a box rule draft which would be foiling friendly, in order to minimize the cost of such boat.

Some target ratios involving: weight/lenght/righting moment/sail area/foil area, should be investigate first, an Excel spreadsheet should provide a good proxy.

So far, we have 4 pages of 50+ posts  on this topic and as one can see, little off these threads aim to move things ahead, instead you can observe endless steril verbal fllows, which aims primarily to sink the thread.

Hi Everybody,

It should be recognized, that all the efforts to achieve foiling within a box rules deliberatly written to prevent foiling, is not the best approach to achieve a foiling cost effective solution,, instead it creates extra costs. 

Weither A-Cat rules must be changed or another foiling cat serie should be launched, I would not get into that fight, but it seems rational to look first for what would be a foiling friendly box rule, and compare with A-Cat box rule, then take a decision.

This has not been done yet.

If unstable foiling like Mischa on his DNA remains the only solution, I am afraid that a big stake of the A-Cat fleet dont feel they are able to do it, and/or they will be to afraid to put a rig at risk, if they capsize. So they will be quickly discouraged to travel for regatta, if they have to remain second league players.

Either DNA will achieve a stable safe and practicable foiling, either rules should become more foiling friendly, future will tell.

That's my 2 cts

Cheers Everybody

Congratulations, but is there any "cost" for flying ? or is it free ?

At first glance one can notice the A-Cat world's champion is not leading the whole fleet despite "demolishing" the fleet downwind ?

Wind conditions were probably slightly lighter than for last World, so "Misha's prefered conditions"

So should we conclude that the new J board have a little performance give-up windward ?

Otherwise Misha should be leading the fleet, No??

Cheers Everybody

So let this topic dedicated to both ChrisO and his peer

Incredible how one can waste  his time writting blabla
