Well, I'll flog an American location I'd settle in if I had remained in the States after attending college and university there. My suggestion is kind of a compromise approach.
As another has suggested, the cruising waters in PNW/coastal BC/Alaskan Panhandle is second to none. And at my age - 72 - I'm not sure I'd want to live 365 on a boat now, when I was younger - absolutely. But I wouldn't mind living on the boat for 7 months of the year up here in God's land.
Since 1974 I have lived with 4 blocks but the majority of the time 1 block of the ocean. I find this gets me so close the ocean I see it everyday and I don't need a view from my living room for the remainder of the day.
If your marina is like mine (Comox), I find some couples are on their boat for months at a time, just tied up to the marina. Not the way I would want to do it but I can tell you they love doing it that way.
I have suggested this area - Whidbey Island - a number of times here at TF. To me it feels like Vancouver Island except downsized, the regular order of fries instead of supersize. It takes a couple of hours driving from top to bottom and about a half an hour drive across. It was where An Officer and a Gentleman was shot.
The island has bridge access at the North end and ferry access at the south end. On average, it is more expensive to live at the south end as many of the residents commute everyday on a ferry to go work at the Boeing plant.
It is rainy but not that bad. The Olympic Peninsula drains the clouds of most of their rain so by the time they drift across to Whidbey Island most of the precipitation has been dumped already. In fact, there is sort of a little desert roughly in the middle of the island.
Vancouver and Victoria is accessible to you to the North (once the plague is over) and Seattle is relatively close to you in the South. The "major" community is Oak Harbor which is a pleasant place to live and is the support town for Whidbey Island Naval Air Station.
If it were me, knowing the great cruising grounds up here, I'd been living the majority of the time on the boat, but in Nov - March I'd being out doing day or two or three trips no more as the wind is a big factor during those months. And I would get something modest, a small home, a townhouse, a condo within a block or two of the water (cheaper) and live there during the off season.
Island living is a slower paced experience. But for me, Islands can be too small, Whidby and Vancouver Island are just right, enough things to do on the island to keep a person interested and active.
