Well we just completed a 33 hour run yesterday from Long Island Sound to the C&D Canal. Sea conditions were mild except for beating into 3-5' head seas for 7 hours in the Delaware Bay. Our boat is a 30T full-displacement DeFever 48. Twin Lehman 120s turning four blade 23x20 props with Velvet Drive transmissions and 2.5-1 reduction ratios. Engines were run at 1400 rpm with no genset time. One engine is fit with a 70A alternator the other has two 108A alternators. The alternators were used many times for cooking, coffee, water heater. Bottom paint is 6 months old. Bottom is free of growth but does have a little bit of fuss on it. Rudders have a bit of fuss and the wheels are clean. A crab pot line was picked up and brought along for the ride for the last 8 hours. Tanks are 80% full. Boat has full liveaboard stores. Winds were following or abeam accept for the 7 hours in the Delaware with 20knot winds on the nose.
