I like the looks of it and I'm sure it would smoke a C275 upwind, but I see three issues that would give me pause to swap. The first is that every picture shows the helmsman sitting in the middle of the bench. It's common for me to sail with four guests, which on the C275 is easy and I'm behind the traveler. Here you would be between the guests and I would wonder if the aft guests would get in the way of the swinging tiller? Second, in typical J fashion, the head is an after thought. I'd take the C275 head configuration any day over J/9's or any J in this size range. This is one of the biggest reasons I hesitate on the J/95. I'm not even convinced there is a sink on this boat. And lastly, no pole on the bow. I like using the asym and thinking of adding a code 0 or similar to make reaching on the lighter days more enjoyable.
Kind of makes me think of an Alerion 28 and maybe that's the market J is competing for. Both are pretty, but in the end, it just doesn't quite do it for me. If J would take the C275 and make it faster, I'd be in.
