On the east coast
so can speak for Cali, but if your check Activecaptian.com you can click on your state and narrow it down form there. Most give information about if the Mariana is liveaboard
friendly. If there is nothing listed in the liveaboard section I have found that it is most likely not accepted.
Some marina at least by me in the NYC
metro area allow liveabords but not on houseboats... Motor
yachts, trawlers, and sailboats are accepted just not pontoon style boats. so that's something you may want to calland check on.
Hope this helps and good luck!
