Although our spinnakers were barely lifting, the fleet astern, some of whom had jibed to port a quarter-mile back, looked to be in even less wind and, at first, the gap between us widened. But then we noticed the sea breeze line was not advancing. It was no longer as dark as it had been. When we were about halfway down the run, the last boats, on port jibe, a half mile astern and to our left, started to move. The fleet rapidly turned inside out.
