Houseboat Marinas comparable to Mobile Home Parks?

[David Edwards]

Anybody in the business of Marinas? Specifically I am looking at marina's capable of and focused on providing docks for houseboats, either year round or as vacation homes. I am seeing anecdotal evidence (needs more research) that Marina's are in the same place as mobile home parks with a lot of mom & pop operators, deferred maintenance, and potential too be more of an infrastructure provider than a home provider.

There certainly seems to be various classes of maria's as well and location matters as areas closer to big cities can charge higher dock rents while still being cheaper than a home or rent.

I'd love any thoughts here. Thank you
