....its a good idea. The nose cone keeps the yak level by preventing the nose to cut and sink into oncoming chop. Without a nose cone....the bow descends too deep into chop and the black ama bars become frequently submerged. This creates lots of spray that makes the ride wetter than necessary. If you dont believe me go check out some videos of A.Is moving into swell and the look for the origin of the airborne spray.
I'd found a dusty nose cone on the floor of a warehouse that just happened to fit my a.i back in 2009. It was a miracle!!!
I said to the owner "hey ...i found this nose cone in the dirt can i grab it for free?" Nope!! I said"but it was in the dirt!!" He said "they find gold in dirt" and subsequently charged me 60 dollars.....fair enough
