Hey, Paul -- There's a growing group of Columbia 22 sailors who are literally in the same boat. In addition to the advice you'll get here on SailNet (which is great!), consider also joining the dedicated Columbia 22 user group at groups (dot) yahoo (dot) com. Search "Columbia22Sailboats" (one word) and you'll find it. Let me know if you have any questions, as well.
See you there!
