Welcome to CF, Cascadian!
As you know, C27s are a dime a dozen in our neck of the woods, so you shouldn't have any trouble finding one & it's an iron-clad guarantee that you'll "get to" reacquaint yourself with boat maintenance!
I'd suggest checking out the moorage situation first, though. Long wait for the civics. If you're moving up to Whistler, boats at Sewell's - Horseshoe Bay, as you'd know - only really take a beating in November. Squamish is no place to keep a boat in the winter though, imho. Don't know how long you've been boatless, but Popeye's is a mere shadow of it's former self & the Steveston Mariner's Exchange closed down earlier this year. In other words, you might want to make sure the fittings & equipment
on your future cruiser are up to date & in good shape. Unless, of course, you're going for a new one...
Best of luck and, again, welcome!
