Watchin the AC this afternoon made me see lots of similarities between the 20 and Oracle, in foil and hull design.

Big notice was the BOR was pitchin a lot less the Alinghi, floats seem better designed and those curved boards probably were doing a nice lot.

Hope fully we shud see these advantages on the new 20 with the curved boards and similar hull shapes? as the new 20 was based on BOR.  Maybee we should get a wing for the new boat aswell to spruce it up even more!!!

 

Well done BOR and Alinghi
There's no such thing as bad day on the water!!

What's the theory behind curved boards?

Very simply to provide some lift to:

 

1, Allow the boat to lift out a little (or a lot) and thus reduce drag)

2, Alllow the bot to be driven much harder down wind as they creat lift and so lift the bows out; There are pictures on the web of an M20 almost taking off on jjust these type of plates.

That it an interesting question. BOR proved that it can
work but would one be too fragile for 'general' racing
use... those C class cat rigs are delicate to say the
least.

Maybe a smaller wing on a tornado platform might work,
maybe invigorate the class for Rio or is this all a load
of Bow Locks?

Norbert, have you ever actually seen a C-class wing face to face? or only in pictures?

They arnt particularly fragile. Certainly the Cogito and Alpha wings are really quite tough and I would imagine that you would only suffer slight damage if you did capsize.
As an example Paul Larsens solid wingsail on Sailrocket took an amazing amount of abuse, and bar a few small repairs soldiered on even having done 2 back flips.
Going back to C-class the wings have developed into something fairly robust, dont make the assumption that they are all like the pieces you see from previous failed attempts in the 80s or the first Invictus wing.

you would need a support team to use one, though, taking the rig out of the boat and restepping it - not as easy as putting the sails up, really.
In the IYRU B class trials in 1968, one of the Tornados had a large wing mast, but not a totally solid one. They came later.
