I had a compac 23 for a while. It was my first keel
boat, and was a great boat to learn on. Easy to sail, built strong, tons of character. The only problem was the very shallow keel
made for poor upwind performance.
I really like the sun-cat. I think it would be a great little daysailer. I would acutally get the one with the very small utility cabin
or even the model with no cabin. I think the cabin on the suncat is really too small to sleep in comfortably, and I would rather have the extra cockpit
