The H16 is a pretty tough boat and can take a good beating. You will go plety fast to satify your need for speed... even in an old design.

Trust me... you will be racing almost every time you are on the water. Any time more than one boat are near each other there is a race <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />

Also, for casual sailing you need to think if the availability and cost of spare parts. For the H16 it is very good. I'm not sure about the Narca.

Good luck in whatever you choose.
