Seems they are pointed outward, are they S boards or C boards?

Posts: 12,310 South Carolina | There is a rule that limits how close together the daggerboard tips can be to each other when fully down...foiling is not technically prohibited - they just made it much harder to do from a technical standpoint.
8.1 No part of each hull or hull appendages below the waterline shall be less than 0.75 meters from the centre line. 8.2 Movable and retractable hull appendages shall be inserted from the top or be capable of being fully retractable into the hull.
I'm not sure how 8.2 applies to rudders...I saw one boat with some small horizontal stabilizers on the rudders at worlds this year...so presumably this applies to daggerboards only?

Seems they are pointed outward, are they S boards or C boards? I don't know what you call them, but they're not C or banana boards. They are designed to allow you to tune the amount of lift vs. side force you get out of the foils. I also wouldn't expect this boat to be fully born on foils - just "lift enhanced".

We'll have to see on the foiling part, won't we? They're S boards and as long as they don't extend past max beam ( up or down) or inboard to the specs Jake stated, they are legal. They were tried on DOGzilla and the Alinghi cat back in the Deed of Gift build up, but I don't think they got used in the actual match. I love this boat,Dario has done an outstanding job. Can't wait to see if it is a performer.
