Thanks for good answers, Karl. Always assumed the minor control on downhaul and rotation on the FX since the mast is like it is. Nothing to compare it to locally since there are few other brands sailing regularly. There are some H17's around and their masts on that platform look even bigger.
hookey, don't know anything about Nacra 17 but from my point of view all the boats 16' and up are on a different, faster level of sailing. That may even include a newer H16. First difference is a larger number of things you can rig up. While it is true of all sailboats 17' and up, you really have to learn the rigging -- to the point, in my opinion, where you first have to become good at rigging up in the backyard before you even get out in the beach. Then there's controls on the water to learn, of course. And if you get an older boat, there is working with dealers for replacement parts or optional stuff which is something H16 owners don't deal with as much because the boat has been around so long and the parts and extras have been designed, modified, improved, and are available and the dealers know H16 parts pretty well. The bigger boats are a great experience, for sure. But I wish the FX were as quick and easy to rig as the Wave! And there were more of them.
