That IS a huge boat compared even to a sailboat of equal length. If nothing else, if you plan to cruise the east coast, consider the cost of slips these days.
I'm not sure whether you are sailing alone, but with that freeboard you'll need some help docking sometimes. Few people are going to be able to jump to a dock from that height, so you'll have to bring her right alongside a dock, and hold her there until someone can get off safely and secure at least a spring line. Using someone on the dock is something I won't do, unless I have no choice at all, and even then, they often do not follow directions well and can really screw things up. I had a "helping hand" secure my bow line to the midships cleat on the dock, leaving me w/an 80 footer crosswise in the slip.
One of the great adventures one can do on a motor yacht that isn't practical on a sailing boat is the "Great Loop" or "circumnavigating the east coast" as I call it. I took a corporate yacht to Nova Scotia, through the Canso Canal to PEI and down the St Lawrence to Kingston. Some do the Erie Canal, but in doing so you'll miss Quebec, which I think is a HUGE mistake. The locks were also a blast (to me).
I went through the Lakes to Chicago, from where we took the Illinois River to the Mighty Mississippi, and down to NO. Last time I checked (a number of years back) 17' was the maximum air draft for that run.
Volvos require almost all OEM parts (super expensive), which makes it imperative you find a really good mechanic, well versed in them, to survey the engines for you.
You might want to look at smaller boats, as they would still be much more comfortable than the equivalent size sailboat, but much cheaper to operate than the one you posted the link to.
Good Luck.
