Got more details on the accident...
The weather was very good so the topman (not the skipper, as he was also the DM), relaxed and after collecting 2 early divers, drifted towards the beach.... when he realized it was time to collect the rest of the group he drove parallel into the backline and flipped... the two tourists were trapped inside the boat... no serious injuries were reported all all divers were safely rescued... the boat's console is broken and the 2 X 100 HP yamaha 4-stroke are probably dead!
