It should be easy
I bought new North Sails for my '77 C30 two years ago and asked a similar question. I was wondering about performance. As far a rigging goes there weren't any alterations needed. The sail gets attached at both ends in the same manner as the fixed foot except the foot is free. It actually makes it very easy to take the sail on & off. As for performance, mine is also full battened. It works fine, I like it. I think it gives you more control if you want to change the shape. I bought from North Sails, they were very good about coming to the boat and measuring. When the sails were ready, the delivered them to my boat, fitted them on and then we went out for a sail and trimmed. Good deal for cruising sails!
