Over the past 40 years I have dived from several dive boats, mostly in the Sea of Cortez and the Andaman Sea, all excellent dive trips. But the lone exception was some ten years ago was the Egyptian dive boat, the Gazala Explorer. Both my buddies and me had a miserable experience on this boat with very poor diving and useless dive guides.
If you or a friend are thinking of diving the Red Sea on an Egyptian liveaboard, please read the following report by the Egyptian Marine Accident Investigation Branch.
In nutshell, the report states that: "16 Red Sea liveaboard dive boats have been lost over the last 5 years. Seven of these losses happened in the last 21 months, and three of these resulted in numerous fatalities."
But dive boats in the US can also be deadly, such as the MV Conception in southen California I dived from many times, caught fire at night, trapping the divers sleeping in it, with many fatalities.
The moral of the story may be to avoid dive boats, best dive from land.
