I believe it. I am hoping to avoid doing this multiple times, the advice I got was to buy my last big boat first. I have been enjoying a 45' Motorcoach for the past couple of years, I can't say it is on par with the complexity and maintenance of a boat, but it has to be in the ballpark.
Not really the same ballpark. Two engines, 4-5 ACs, exposed props, boat sinks if you screw up, etc. And pavement doesn't move, whereas wind, tide, and current remove the whole idea of "firmament" as you're trying to park (dock).
Good luck with that "last first" thing; it's really difficult.
Since folks have morphed into advice mode, I'll add a thought that has helped us: when you're looking at (on) a boat to evaluate whether it's for you or not... imagine yourself actually doing each/all of the various tasks and chores that come with boating life.
In the house, don't just look at the shower... instead, imagine yourself taking a shower. Is there room to turn, bend, etc? Don't just look at the galley, imagine yourselves making breakfast or dinner. Enough storage? Cooktop or whatever easily accessible? Don't just look at the bed, imagine climbing out of the rack for a midnite trip to the head. Et cetera.
On deck, imagine yourself docking. Who stands where to do what? Can you see all round the boat from the helm? How do you communicate with each other? Can you reach cleats on the dock from onboard the boat? What if there's no dock hand -- or even worse (and not uncommon) an incompetent dock hand? Et cetera.
In the engine room, imagine yourself changing a raw water pump impeller. Imagine yourself changing the oil and filters. Imagine yourself changing the fuel and filters. Et cetera.
We had really good luck with buying our first big boat, and we've been able to build on that... but our first wasn't our last, and each boat since then has become an informed improvement over what we had before. Some of that of course being because our needs/wants morphed gradually over time.
I hope this is helpful. And good luck with your search!
