1) What is the differecne between an I20 and Nacra 20?
The Nacra 20 is just the new name for the I20. Same boat.
2) What are the benfits/cons to end pole or midpole snuffer system?
End pole has a lot of windage where it doesn't need to be. People say its easier to snuff, but the consensus on the race course is that the midpole is a better solution. It also allows a better tackline solution.
3) What does a new main or jib or spin cost?
I believe a new main is $1500, Jib about $500, Spin about $1400. These are of course always subject to change.
4) How is the boat righted after capsize?
Same way any other catamaran is righted. You get the righting line out and you pull it over.
5) What should I be looking for in apreowned boat?
These boats are solid. There aren't really many problem areas on them that I can think of. Just make sure that it looks like it's been well-cared for. Make sure the tramp doesn't look old. The slot-fit tramp system can be a PITA to get right but the latest solution from EP that I have on my tramp has worked wonders for it.
6) What should be a warning sign in a bad boat?
See above.
7) What are the set up and derig approx times?
1 person can take up to an hour. 2 People can get it done in as little as 20 minutes if both know what they are doing and are motivated to get on the water.
8) Ideal combined crew weights?
360lbs up to 400lbs. The N20 handles weight really well.
9) Are there tuning guides availiable for the boat?
