Hi Jack,
The 500 has a lot of advantages such as:
- can right it single handed
- simpler than a H16 so less things to go wrong.
- lighter than a H16 at 300lbs.
- more stable than a H16 because of better a hull design.

They are plenty tough enough to do any type of sailing you want to do. Most modern boats are built a lot better and stronger than the older designs.

There are Nacra dealers all over North America and some dealers have 500s in stock if you want to check one out. If you are in Ontario Canada I can get you a demo ride.
