Sipping cold ones from the cockpit cooler under the substantial dining table, we eased ourselves 10 or so miles out to sea. The large center cockpit, twin wheel positions and quarter seats aft provide a number of nice spots to enjoy the thrill of sailing. We eased the sheets and reached down to Nonsuch Bay before the tricky piloting started. Pressing buttons again to trim the sails, we settled down to a speed of 10-plus knots. Most big boats reach well, and the 66 is no exception, but I was impressed she held her line as well as she did when the big quartering waves tried hard to squirt the stern sideways. This exemplary behavior is the result of her fairly heavy displacement (83,774 pounds) coupled with a modern underwater shape, keel and rudder. The underbody is deeper than those of lightweight flyers but shallower than traditional cruisers, and does not have flat surfaces to pound. The keel has twice the chord length and maybe half the span of a high-performance racer/cruiser, but the shape is effective. A ballast bulb at the tip lowers the center of gravity for good stability while reducing drag. The skeg-hung rudder is large enough to take big bites of water for quick, accurate steering response.
