I corresponded with the Blackfeather folks about the cruising version before they had finished one. As I recollect the cost was going to be fairly close to $200K. I'll have to read all of Ken's reports. There a number of things I like about the boat, but the beam is 10 1/6 feet. This wide load goes into another category where there are more restrictions than at 10 feet. I would love the see the tunnel a little higher, even tough it is higher than the Tom Cat 255. I also more of a gull wing area under the bridge deck (not as flat--and less chance for slam.
I got a chance to get a very good look at the Motorcat 30 this last week. It is an interesting boat. Interior layout is very good and sleeps 4 easily. But the side decks are much more difficult to negotiate than in the Tom Cat. the cockpit is much different-and it is more of an express cruiser. Also semi displacement (with pads aft) hull so it is a slower, lower hp boat.
I have looked at the larger ProKats, Glacier Bays, TwinVee's, and World Cats, plus several custom boats (think $600K up to several million --but a whole different type of boat)
