The 4th day of diving. The first of which without any courses. We had planned 3 days of courses and 3 days just diving. There was a strong wind from the north this day, so we came to a site on the south of a reef for a bit of shelter. Guides today were Simon and Petra. We had planned to follow Simon, but lost sight of him. So we just explored a bit on our own, with Petra keeping a watchful eye on us, until we ran into Simon again.
