Seeking advice about Catalina 16.5K boats

[rictalden]

I plan to buy a used Catalina 16.5K fixed keel boat. I would appreciate any advice about towing, trailer weight, launching, storing, or anything else that may be important. I eventually plan to keep it docked at a lake but may be towing it to local lakes until I relocate. A heads-up on any boats for sale in California would also be appreciated. Thanks!
