Wow, souljour, I just went to sailboat data COLUMBIA 40 sailboat specifications and details on sailboatdata.com
and checked out your boat, looks really good. I'd love to try out a keel/centerboard.
Drop that board to 9 ft. and seems you could go upwind nicely, plus track downwind with the keel.
Wolfenzee, your boat sounds great, I really like the lines. I've only really been (sailing) on wooden full keel boats, so I'm not sure how the fins handle. I've been on one, but they only motored
