First 3D rendering of the new boat for the Super 12 cup.  I really like it except for one thing.  Not that it matters but why the wings on the keel?  Those were done by the AC teams in an attempt to generate more lift than the competition without going deeper with their keels.  If these boats are all one design why deal with the hassle of the wings?  You don't need them...just make the chord length deeper on the keel or just go without all together!

I'm pretty sure the reason for wings is they are trying to limit draft so that the boats can get into at least some yacht clubs and more yards.  It's still fairly deep, and I think they are still messing around with some design parameters.

 

I completely understand the need to limit draft but given that the playing field is made even because it is a one-design boat there really isn't a need to add a wing - which only adds complexity maneuvering the boat on land and with respect to maintenance - and adds zero marginal performance improvement (boat to boat).  Again, small potatoes in the big picture but it just struck me as odd (like the guardrail for the 13th man).

Sorry to see we lost a member of the 505 family.  My condolences to the family - and his extended 505 family - in Canada and beyond.
