On a windy day a J/24 is better with 5. On a windy day, of course sailing is more work, regardless of the boat type. And there are handicap fleets that are not as competitive as one design where J/Boats are used, so I disagree on some comments above. And, the J/22 is a really neat boat and fast. If you are racing one design, then all the boats are the same and you play that game. If you are racing in a handicap fleet, it is more fun to have a fast boat or at least one that is competitive with your competition. It is no fun to be the last one across the line and the race committee is patiently waiting for you to finally finish. If you are new and learning, That's one thing. But if you have a slow boat that can't get out of its own way, then you need to find a different boat. One comment is about having to fly a spinnaker. Well, that is part of racing. If you don't want to own a bag of terror, then sail the beer can races and don't worry about it. Find the level you are comfortable with, but don't let someone else tell you what your comfort level is based on their comfort level.
