Well at this stage, I can pick the most cost effective location. The boat will be my residence and I plan on cruising the Bahamas then the loop.
I will have no land based home. To say I'm flexible is accurate.
But then you need to reestablish residency. You're still a California resident. Where are you living today?
Some steps needed and the reasons why.
-Drivers license and insurance changed.
-Physical location and legal address changed
-Bank account opened or changed
-Voting registration changed
-Physical location of both you and anything you own.
Why?
-Until you establish somewhere else as your legal residence, you're subject to California income taxes, property taxes, and other.
Florida and Texas are easy and used by many boaters and RV'ers. There are places in both states specializing in helping set up up. However, until you make the moves to change, the old state still has a hold on you.
This is all separate from where you register and keep the boat but can play a role. May be wise to consult an attorney. I don't know your income or if you have insurance settlements coming or anything else about you.
We went through a relocation from NC to FL in 2012. We accomplished it all in less than a week but that was a rapid pace. NC made us provide proof of the new residency with the things I mentioned above as they wanted to tax out income after the move.
