Well, to operate in the Similans, boats theoretically need a Similan License. I do know of one boat that wasn't even registered in Thailand and still operated without any problems though
There are speedboat operators who take safety seriously. They have first-aid trained staff on board, they have radio, plenty of life jackets, don't take too many passengers etc. The problem is that they are more expensive than the others. When I worked in Khao Lak I only co-operated with the "safe" ones (I have strong principles when it comes to safety - both boats and diving). The vast majority of tourists would ask about the price first and then leave the shop when they heard ours. In the end, my response to their price inquiries was "we're probably the most expensive in town". Most people left, some people were intrigued and asked questions - and then I always got the booking, because I could explain about safety and service level. BUT most tourists were only concerned about the price
Hi Aquamarin,
Unfortunately for a lot of tourists price is indeed the most important factor. I think that a lot of tourists just automatically expect the same safety standards as 'back home', not realizing that things are slightly different in Thailand and many neighboring countries when it comes down to 'Western standard safety issues'.
It's not until an accident/incident occurs that they realize that things are different.
