Big time offshore shakedown, 24 hour run westerly, tacking out of the gate, with an awsome headwind as usual. Great trip, a little quezieness on board, cold and foggy throughout the night so the night watches froze. We picked up a crab pot after firing the engine in the middle of the night, when we had zero wind, zero visibility and was time to start east. Discovered crab pots can present and immediate emergency situation, crew performed admirably. So far damage appears to be the shearing of all of the bolts holding the tramission output flange to the vibration damper. "No mo go" Short tow, thank goodness for BoatUS.
