Good boat for the usage you described.
I owned a '91 Skier for 8 years and loved it. My primary use was slalom and that boat has a great wake. I'm sure it would do good for barefoot also. Can't comment much on the wakeboard wake, but we did play a little with it and had fun.
We ended up moving up to a larger boat for the space. Like any closed bow direct drive from that era, more than 4 people gets cramped really fast. The only usable space for stuff you need to get to is directly behind the drivers seat. A tower with board/ski racks would help.
Also, Malibu went to all fiberglass in '93, so check the floors closely. From the looks of the interior, I'd expect soft floors.
I believe I have an old Waterski Mag. review of that boat if you'd be interested in seeing it. PM me and I'll scan and send you a copy.
