Sailing Anarchy would be a good place for this, sailnet tends to be more monoslugs and cruising cats. I've got a monoslug along with a beach cat now, I enjoy it but it's a very different kind of enjoyment.
Is this your first cat? Some are a lot easier to sail and to right than others. I sail double-handed but sometimes my skipper takes ours out solo. We started with a Hobie Getaway which was fabulous for learning on but being fairly aggressive we grew out of it in a few years. It was fantastic for taking a few people along (even 4 adults) and we didn't have the wings. Things happened relatively slowly so we had time to think and make the appropriate corrections to avoid going for a swim.
When we decided to move up to a faster boat, the skipper decided he wanted an F18 (Hobie Tiger but Nacra makes a lot of them). It's a lot faster and not nearly as forgiving. One of our first times out he commented how it wasn't all that much more difficult to handle and react to than the Getaway. We were in the water less than 15 seconds later. Flying a spinnaker
is great fun though. The 18 is a bit much even for him to right and solo. If I were buying again I'd look for an F16: designed to single-hand but still fun for 2. We avoid taking 3 people out on the F18 since they just get in the way and there are lines
everywhere. So even if you want to take out an extra person or two, I'd focus on getting a boat that you can sail and right yourself, even in swells.
I like the Hobies, a lot of people love their Nacras and Prindles. It depends to some extent what people use in your area. Even if you don't want to race, it's a lot easier to get parts for common boats. The a cats will be a lot to handle if you don't have a lot of cat sailing under your belt. I love the F18 but there's no way we could've started on it and it still scares us frequently. Stuff just happens to fast to learn. Hobie 16's are highly popular but I really like having buoyant bows.
For the most part, cats will take swell nicely. The first guys who crossed the Atlantic did say they'd never do it again and they strongly advise against anyone else doing it.
If you're singlehanding, think about how it's going to get in and out of the water and how much it weighs.
