Overcrowded boat with Master Divers? That is new to me.I understand. We have been there on Koh Tao for a month, diving with Goodtime Adventures. And I much prefer a speed boat. You get there much faster that the old big fishing boats others shops prefer to own with 30+ divers on them.
You ride on the big old slow overcrowded boats, I will be on the speed boats every time.
I have never been on any boat with Master Divers that had more than 20 divers. There are similar other operators as well.
I only need two dives in the morning and has plenty of time on a slow boat to enjoy the view as well as the company of other divers from all over the world. There is NO rush on a diving holiday.
Similar experiences in Koh Lanta and Koh Lipe.
