You Catalina 27 owners could do as I did for my Tartan 27. I started a Yahoo group called T27Owners. The Group allows you to upload photos, post files, links, databases etc. It is free to set up but someone has to do it and be the owner/moderator. I nominate Smackdaddy for the job!
You do need to set up a Yahoo id to use the Groups function.
T27Owners : Tartan 27 Owners Yahoo Group
Alternatively, there is a Catalina owners group over at SBO, CatalinaOwners.com - Home
which serves all the models.
Or, you can stay right here.
