To suggest that cruisers in general prefer full keels is simply not sustainable. Some do, no doubt but in this day and age a goodly number don't. Yesterday coming down the coast we passed an old gaff rigged, no doubt full keeled, schooner. Passed being the operative word and the Womboat is no greyhound. No thanks, not for me. I've owned and sailed both full and fin, albeit moderate fins and i'd not choose to go back to full. Otoh Bob Perry's Babas are fine boats as are Bill Crealock's efforts. Horses for courses as it were, the issue is not black and white.
