No dolphin striker to hit waves is faster.

I dont know what happened to the rules in 2010 as the ISAFisation process was going on.. Look at this for the rudders in a PDF of the 2010 rules I found on the forum on the class website.

Quote

E.4.4 CONSTRUCTION
(a) The cross section of each rudder shall be symmetrical about its fore and
aft centre line .



Now what does this mean?? Rudder winglets certainly is allowed in multiplie configuration and is used in the class but this effectively does not allow L-shaped winglets. No discussion, no ballot and comments..
