Welcome To M.V. Trident.

MV Trident is  located on Koh Tao, a small island in the Gulf of Thailand easily accessible from the mainland at Chumporn or from Koh Samui.

Accommodation is varied on the island, varying from basic beach side bungalows to luxury resorts. If you or your family would prefer recreational land based diving we can arrange this too with our sister school Master Divers. There are many activities for non-divers too.

Although recreational diving has been popular here for twenty years, and we’ve been diving our local wrecks for that time using fishing boats, real world class technical diving has only been available since we bought the Trident in 2005

We have 90,000 sq. miles of relatively shallow water  ( less than 80m) to explore. The Gulf has been a major shipping route for hundreds of years so we’re able to dive wooden Chinese pottery wrecks, WW2 ships, aeroplanes and submarines, and modern wrecks.

Since our maiden voyage we have  discovered dozens of major wrecks,  nearly all WW2 and all virgin. (We also found a lot of rubbish too!- see the ‘Rubbish Wrecks’ page).

The USS Lagarto was the most publicised but there are still many more stories to tell including the 1945 route of USS Hammerhead who sunk several marus in the Gulf of Siam.

Japanese records state that 179 marus ( merchant vessels) were lost in the Gulf of Thailand in WW2, we have hundreds of co-ordinates waiting to be dived, some we’ve seen on the sounder but not had a chance to dive yet.

We run Exploratory expeditions on a regular basis , and although there is never any guarantee of great new wrecks every trip, our success rate is very high. If you like un-dived virgin wrecks and are prepared to ‘get down there and see what it is’, these trips are perfect for you.

The Gulf is an ideal place to dive, the water is generally clear, any currents are mild and the seas are calm. We can dive year round in the gulf of Thailand, although the NW monsoon can blow hard in November and early December.
