Timshel - Cocos to Mauritius Day 4

Faster sailing, even reefed overnight, some rain squalls. The yachts ahead are still reporting more wind than we have. We saw a ship last night and one at lunchtime so the ocean is not completely empty. We need to change the chart chip - we seem to have come to the end of the Indian Ocean one and need to change to Africa - still 1926 miles to go to Mauritius though.
