Welcome to the forum. There are about forty million Grand Banks up here. I would not be surprised to learn that there are more GBs in the PNW and BC than in any other region in the world.
The boats are coastal cruisers, not open ocean boats, so the mostly inside waters of this region from Olympia in WA to Glacier Bay in SE AK is ideal for Grand Banks. So while it's always possible that a GB owner may know so-and-so who is also a GB owner in this area, the huge number of GBs here can make that a statistical unlikelihood.
I'm guessing there are perhaps between thirty and forty GBs in our marina alone. While we are not social boaters by any means a GB at the dock or in a slip tends to cause other GB owners in the marina to wander by and say hi at some point. But of all the GBs in Squalicum Marina I know just three of them by name.
So don't be too surprised if Jay (Scout) who is one of the three I know, isn't familiar with Walt and Margie. But he might be, you never know.
The Ranger Tug is quite popular here, particularly the 27' model. Don't see many on trailers, however, as I assume it requires a pretty stout towing vehicle. The ones in our marina have permanent berths.
A good friend of mine has ferried new RT27s from the Seattle area to owners up in BC--- the upper Sunshine Coast, Campbell River, and in Desolation Sound. I have never been on one but according to him they are outstanding boats for this area. Anacortes is a good place to base out of as it's right at the south end of the really good cruising waters here.
