My first real motorboat was a 1963 Chris Craft Constellation. My dad and I owned it for 19 years. It's not exactly a modern express cruiser. You have two choices. 6 knots or 16 knots.
Displacement speeds is not really comfortable, or fuel efficient. At 8 knots, the bow is pointed skyward. Those types of yachts are suited for the bay on nice days. But for living aboard, if you like the studio 54 type of look I guess it would suit you. For the same money, the Californian has the diesels, a much better ride, is better looking (in my opinion) and is here in California. You could have that on a truck to Oakland next week. They are not at all the same boat.
A younger member of my club has a Bayliner express cruiser. We can't really buddy boat because he has to go full tilt boogie or way slow. I guess express cruisers are my least favorite type of motor yacht.
Things that are important to me, straight drives (or Vee), not I/O, Good visiblity, pilothouse or sedan (I'm a longtime sailor had have had enough of being outside in foulies), galley up, easy to make bed, icemaker, washer/dryer. Those last two items make living aboard very humanizing. I'm sure there are many here who don't agree.
The 1968 Chris Craft below is for sale in Kelwona, BC. $30000 (USD). The one with the white bimini was mine, the washer combo is on my current boat. I can't the pic to rotate.
Shit man, take a serious look at that Californian. If I had room in my life for another boat, I'd be tempted. My babe would kill me.
