We didn't make a "switch" from boating to RVing --- we just jettisoned our 30 ft power boat. After having owned boats for several years, we learned that, unless you have very deep pockets, it is like a hole in the ocean into which you throw money. The cost of moorage fees, maintenance, repairs, and fuel can be prohibitive - especially salt water boating.
Marinas are nice but can be expensive depending upon where you decide to dock - just like RV parks. Many boaters, including myself, enjoyed mooring/anchoring rather than going into marinas - something like dry camping in a way.
Many marinas have pump outs so you can get rid of your waste, plug into electricity and hook up to water and, in some cases, cable TV and the internet.
In boating, the journey from A to B is what makes it enjoyable, not the destination. In camping, it is almost the reverse although you can sit back and also enjoy the scenery along the way. The journey is more work - especially if you sail - but sailors do not think of it as "work" and is open to more adventures along the way.
While at sea or on the open water, you DO NOT want to have engine breakdowns, leaks, etc. There is no place to pull off and get it repaired quickly and usually no emergency road service that will come to your aid - unless it is an emergency of some sort. It is more "risky" than RVing and probably better suited for healthy, younger folks who don't mind a little rocking and rolling when at anchor --- no Steadyfast system for boats to make it "rock solid".
It's quite different from RVing and not everyone's cup of tea.
