Yes,
The Puget Sound Cruising Club has a lot of activities. A friend of mine was a commodore there for a couple years and I have attended some of their events both on the water, and some of the online events they have had with speakers and such from time to time during the winter.
As somebody else mentioned, a lot of this depends on what you are looking for out of a club.
BYC: I have been member there since 1991. My girlfriend and I were (by far) the youngest members back in the mid-90s when she joined. In the 60s/70s/80s, it was very much THE place to have a fancy dinner. By the mid 90s it was on the verge of bankruptcy. It got much more focused on boating/sailing, changed the clubhouse to fully separate off the restaurant side, etc. and completely turned around. It is now kind that traditional 30/30/30 balance of power, sailing and social.
Today it is kind of trending back towards more social activities, but still active with both power and sailing. The sailing events tend be oriented around the Wed/Thu night racing scene, and the cruising events are both power boats and sailing leaning heavily towards the power boats.
Bellingham CYC: Never been a member, but was a member of Seattle CYC for some years. In my experience in Puget Sound and visiting elsewhere during work travels, Corinthian clubs in general tend to be very much sailing focused, with a heavy dose of racing. For Bellingham, from my recollection from 'back in the day' - lots of racing events in coordination with BYC, and some but much on the cruising side of things.
Squalicum YC: I don't know much about it. When I was younger a friend of mine rented their space for band events some times. As others have surmised, I think they are more power boat oriented.
PSCC: Lots of cruising events, heavily sailboat focused. If from Bellingham though, they tend to be more South Puget Sound. Also, they do not have reciprocity with other clubs for free moorage and things like that.
Sloop Tavern YC: If from Bellingham, too far away, but an awesome club, lots of activities, and cheap membership. I have been a member there for about 10 years. If these guys were in Bellingham I would say hands-down, the best club for activity/events/fun vs. dollars and 95% sailors with a few folks that switched over to the dark side due to age.
I would suggest simply reaching out by e-mail to both Bellingham YC and CYC Bellingham. Tell them about your yourself, your boat, and that you are curious about membership. Get an invite by somebody off the membership committee to go on down to Bellingham YC either on 'jam night' - or either club on a Wednesday after the races, and meet some people, hang out, and check out check the vibes?
If I was up in Bellingham I would invite you to meet at BYC anytime already, but I am in Poulsbo mostly now and won't be around until mid-summer.
EDIT: Re-read original post. PSCC might be the fit if heavily cruising focused, but again most of their events and members are South Puget Sound.
