All was going well for a full 24 hours as we glided south under cruising chute in 12 knots wind. At about 3pm yesterday after gybing to keep our course all went completely silent. Not a sail noise, hull sound or rope creak. Silence was not a good thing. We watched with fascination and horror as our cruising chute dropped to the sea beside us. The halyard had chafed through. So started a long arduous recovery of a sea anchor into the cockpit. Now 180 miles to go or 24 hours of rolling under mainsail only. Headsail furling drum still not fully locked & controlled so staying fully furled.
