boat dive


Not enough weight (underestimating the effect of the 7mm wetsuit and the aluminium tank), after upgrading to 9kg it worked well. Went down along the mooring line to the Iron Reef, which is an artificial structure covered with soft and hard corals, and attracts lots of fish. The structure also features some old truck tires that seem to attract the fish for the algae which grows on it. Nice visibility (about 30 meters), but also many many divers under water at the same time. Needed *lots* of air.
