About Alex
Originally from Leeds in northern England. Alex is a tech divemaster and rebreather diver with a strong understanding of CCR diving and decompression theory. He’s passionate about the technical side of diving and always happy to chat about gear, gases, or how to make the most of your bottom time. He’s great at mixing this mindset and approach into our recreational dive setting.
Alex is also involved in Big Blue’s conservation efforts and takes pride in helping protect the marine environments he loves exploring.

Whether he’s assisting on tech courses, guiding fun dives, or supporting rebreather divers, you’ll find him approachable, helpful, and always keen to share. He’s especially passionate about marine life—just ask him about boxfish! (He’s a bit obsessed.) With Alex, you’re in good hands for a dive that’s safe, fun, and full of fish facts.

Our Similan Liveaboard Trip Reports

03 – 07 Nov 2025
Trip 3 of the season is back in the books—and despite some spicy forecasts, we juked the worst of the weather and still pulled off a winner, with big smiles and even bigger visibility.
28 Oct – 01 Nov 2025
There’s something truly magical about opening your eyes in the Similans. We woke to gentle seas and a light rain shower passing through Hideaway Bay – but spirits were anything but dampened! Instead, it gave us a peaceful start and plenty of anticipation to get underwater.
16 – 20 Oct 2025

Blue Dolphin Kicks Off the Season in Style! 🐬

What a fantastic start to the season aboard the MV Blue Dolphin! A huge thank you to all our amazing guests who joined us for our first Similan & Surin liveaboard trip of the season — we loved being back on the boat, an unforgettable few days out on the Andaman Sea.
