Our Similan Liveaboard Trip Reports
Good vibes, dance moves, flat seas, cold beers…
Without succumbing to the curse of ‘jinxing it’ that seems to be the cause of so much outrage on the typical dive boat full of enthusiastic and hopeful divers; the calm waters of high season are finally upon us! Trip 25 was an absolute banger with a wonderful mix of returning and fresh faces.
Trip 23 has returned to land and what an epic adventure it was. With Team “Rest of the World” being only 4 customers and 2 staff for this trip I for one was super grateful that everyone clicked and we had such a nice time both above and below the water.
