Welcome to Mariner I

Our trips cover the following:

Similan Islands, Koh Bon - 3 day / 3 night

Surin Islands, Koh Tachai, Koh Bon, Richelieu Rock - 3 day / 3 night

Similan Islands, Surin Islands, Koh Tachai, Koh Bon, Richelieu Rock - 6 day / 6 night

Maybe you would prefer to spend the majority of your time diving either the Similan Islands, or the northern island dive sites of Koh Tachai, Surin Islands and Richelieu Rock. Or if you have enough time to spare, combine these two trips for the ultimate 6 day trip in the Andaman Sea. Then, we invite you onboard the Mariner One. Recently renovated, the Mariner specialises in comfort and personalised service, featuring air-conditioned twin cabins on the lower deck, two air-conditioned double cabins on the middle deck, hot water showers, an extended outside covered dining area so you can enjoy the view as you dine and a spacious extended sundeck, partially covered, complete with sun mattresses, sun beds and hammocks.

On the Similan trip you will have plenty of time to dive many of the famous dive sites in these islands, and in-between dives either relax onboard or go ashore to the white sand beaches. On the final evening, join us and your newly found friends for a relaxing and usually lively evening onboard with sunset cocktails and a barbecue dinner on the open air sundeck. On the northern trip to the Surin Islands, dive the more challenging and adventurous dive sites of Koh Tachai and Richelieu Rock, whilst also visiting the Surin islands for some beach time. Here we also offer a cocktail on the final evening - on the 6 day trip you’ll have two!

Would you like to keep a permanent memory of your diving trip? On many departures of the Mariner One our onboard videographer will be filming both above and beneath the water, and at the end of the trip you have the chance to view and purchase this personalised memento of your time onboard and underwater. . .
