Guy next to me on pontoon many moons ago (late eighties?) used to have one. Bit of an unusual layout but quite a lot of accomodation for size. Had twin 145hp Volvos on outdrives and boat did about 5 knts at tickover which made berthing a bit interesting. Depending on where you live, raised helm position is a bit exposed in weather with no real option to cover with canopy but other than that she was quite a good sea boat.
Engine access to do any real work was hopeless. Even routine maintenance was difficult.
