and I want to move to Vancouver and live on our boat." Hmmmm this must be a question googled quite a lot these days
I would consider doing what some SF Bay
Area sailors are doing who cannot find live-aboard slips for the same reasons mentioned. Some get a slip and buy a small RV to stay in on the off days or a second boat. Although, some marinas just don't care about the liveaboard rule
(particularly where it is not the top choice to live - see boatyard marinas or ones in less desirable areas).
It shows this is your first post so we don't know if you are new to sailing or not. If you are looking to liveaboard for the first time or to look for affordable housing options please, please, please learn how to with regard to the environment
and your neighbor.
Good luck out there!
