The thinking is that T-foils on the rudders make the Stealth "virtually" 4 feet longer. Without going into a debate on this, which we have had before ( smile ), the conservative conclusion is probably still "not enough data".

Good question about carbon masts. Never heard that modern A-class or other carbon masts had issues. Masts come with UV filtering clear coat or paint so it should be OK. I think I would want a white painted carbon mast though.

Today we have about 1 meter of snow outside our house and I am about to put on my snowboard. You on the other hand have UV and heat to worry about *boggle* grin
