Congratulations @jewel. Knowing that the name came from South Africa surprised even me. Had no idea they made a Catamaran. Found a link https://www.cruisingworld.com/sailboats/knysna-480-new-cat-set-prowl that tells more about the boat.
You’ll be having some fun and may not need an internet group. More like a group of other boaters who enjoy sailing.
Fair winds and welcome.
