For The living in CA and registering in AZ, it would depend on the value of your boat on wether it makes sense for you to do this or not. In CA you pay $20 a year for registration, then a "supplemental property tax" which is 1% of the value of the boat. State values my boat at around 60k, so I would get a tax bill of $600 per year. (Amazing how boats don't depreciate with the state assessor). In AZ a non resident registration is based on the length of your boat. (I register in AZ). My registration there is $239 a year. Still saving me $400 a year, so for me it's worth it. I use my boat in Parker a lot, but do visit lakes here and I've never had an issue. The trailer is registered in CA, as it is two different items. If the value of your boat tax would be less than the non resident registration, not worth doing. BUT, AZ does not have sales tax on buying a used boat, so if you bought a boat, registered it there right away, you avoid the sales tax
