Its pretty simple
If you going to cruise and plan on anchoring out alot, nothing beats the 3'10" draft. Catalina added 100 pounds of ballast to make up for the shorter keel over the deeper draft model. I can speak from experience as a 2-year ICW cruiser on a Coronado 35 with a 5'6" draft several years ago. My draft kept me from many anchorages whereas a wing keel would have made its way in easily. I ran aground more times then I care to remember in areas that were marked over 6' on the charts! Today as the USCG puts more budget into homeland security and less to dredging waterways, your going to encounter more shoaled in areas, making the wing keel a more attractive choice. I just purchased a 1988 C-30 with a wing keel with the expectations of heading back to the ICW for some extended cruising. That means traveling hundreds of miles of waterways with only a few feet of water between the keel and bottom. That also plays into getting through shallow inlets. The wing keel is my personal choice based on the aforementioned concerns. Things like which keel provides more stability in racing, and how much more can I expect to list in ocean swell conditions are not an issue. For my piece of mind and for my needs the wing keel gets my vote. If you have never seen one up close by the way, that are massive! Out of the water you can easily sit three adults on each wing.
