For this boat, the centerboard makes a big difference in how it sails. Without the centerboard, the stub keel does not provide much lift when going to windward, and it makes it difficult to pinch up close to the wind.

The centerboards on the Oday trailerables (22, 23, 25) are really simple affairs, and require the least amount of maintenance of any system used by the big boys. That being said, they still do require some maintenance.

My two cents (adjusted for inflation): if you like the boat (and I think it is every bit as good a boat as the Catalina 22), find one with a centerboard: it sails better than the stub keel model, and its just as easy to trailer.
