Unicorn Wreck

By , 25 July, 2014, No Comment


It has always been rumored that at the time of it’s sinking in 1989 the 60 meter long Unicorn was sunk on purpose as an insurance scam. Local Koh Tao inhabitants said that the ship just pulled up off shore, around a mile north of Koh Tao and over the next couple of hours slowly sank after an explosion on the vessel. No-one was hurt in the sinking. An Insurance fraud was immediately suspected, insurance investigators were sent to investigate the cause of the sinking and to confirm the cargo which was listed as expensive Tuna Fish. Divers descended to examine the wreck, and discovered that the holds contained nothing but low-grade animal Feed (Dog-Food) un-fit for human consumption, NOT expensive Tuna fish as listed on the manifest. hence the nickname it later aquired – the “dog food” wreck.


Lying around 12km north and 20-30mins off Koh Tao and in 50 meters of water the vessel lies, mostly intact, on it’s port side at an angle with the top of the bow at 38meters, and the keel of the bow area several meters above the seabed, allowing divers to swim under this area of the hull. Fishing nets have been removed from the wreck allowing some moderate penetration. Big schools of jacks, batfish and barracuda patrol the area directly above the wreck with a pair of large groupers residing inside the wreck. Here at DJL we often dive the Unicorn as part of our Technical diving program, especially the Tech 45 course. Due to the depth and location it is always quiet and diver free. I dived the Unicorn for the first time in march last year, as the visibility was very good the wreck appeared to have an eerie greenish around the outline of the wreck (maybe just narcosis) and was enthralled by the always curious bat fish.

Tanote Bay (By Ed)

By , 14 July, 2014, No Comment

Tanote Bay


Tanote Bay is located on the Eastern Side of Koh Tao meaning its sheltered location makes it an ideal dive site when other dive sites of the island are affected by southwesterly winds.  Easily identified by the massive granite boulder at its centre (also popular with cliff jumpers) the palm tree lined bay in the definition of idyllic tropical beauty.  Under water the bay features some of the most beautiful coral gardens in the gulf of Thailand.  It also boasts a selection of features that make it the perfect place to go for a dive, whether working towards a qualification with Davy Jones Locker’s experienced, multilingual team of instructors, such as the PADI Open Water and Advanced Open Water diver courses, or just looking for an interesting and different fun dive.  As well as the stunning coral formations surrounding the boulder there are a few cool things to see here.  Practice your navigation skills by trying to find the wreck of a catamaran located a short swim from the rocky outcrops at the North side of the bay.  Heading back towards the main bay is a somewhat smaller wreck (an abandoned motorcycle!)  Heading back towards the mooring buoy takes you past one of the many artificial reef projects on Koh Tao.  Produced in association with local marine conservation charity, Save Koh Tao, and PADI’s project AWARE the artificial reef area consists of a series of reef balls, designed to promote the growth of coral and is a great example of divers working towards a better marine environment.  Book your next underwater adventure with DJL diving today!!!

I recently attended the IDC staff Instructor course at Davy Jones Locker Diving on Koh Tao in Thailand and found it to be a really interesting and valuable experience, working with DJL’s team of outstanding course directors and staff instructors as they conduct the PADI Instructor development course.  DJL offer ICD’s in English, French, Dutch, Spanish and Korean so on a DJL IDC you get to meet interesting people from all around the world and make contacts that will be helpful throughout your diving career.

The aims of the IDC Staff course are to improve all your areas of diving theory knowledge and PADI standards to a level where you are able to help with the development of the next generation of PADI instructors.  You learn how to mark and give feedback on all areas of the IDC including confined, open water and classroom presentations.  Seasoned instructors will love the ability to pass on their experience and knowledge to trainee instructors as they take their first steps towards building themselves a future in this amazing industry.

Take the next step today and contact DJL to arrange your IDC staff instructor course today, do it now, you will never look back.

Ang Thong National Park Expedition

By , 31 March, 2014, No Comment

tham thale nai topo

We just returned from a great cave diving expedition to Ang Thong National Park in the Gulf ofThailand. The aim was to locate the cave that feed the saltwater lagoon on Koh Thali Nai, this saltwater lagoon is in the center of the island and surrounded by sheer cliffs. The lagoon is a saltwater cenote and fed by an underground cave to the sea.

 We found this map by some French cave explorers locating the entrance on the eastern side of the island. The main problem would


be locating the cave and predicting the flow in the cave, as at sometimes the cave would turn into a syphon, pushing you into the cave making it difficult or impossible to exit if the cave is impassable. Syphonic conditions are also dangerous as you need more gas to exit and sediment stirred up will washed into the cave with you.

We quickly located the seaward side entrance not far from the beach, with a high flow running out of the cave just one hour before low tide, as the lake was emptying into the sea. The cave was wide nearly 5 metres across but only 70 cm high making sidemount diving the only choice. After a primary tie off on the surface we descended to the entrance. With 3-4 knots current flowing out of the cave, it was impossible to swim against. Tim Lawrence and Myself had to push and pull ourselves along through the restriction. Each metre of penetration was hard work wriggling through the restrictions and pulling against the current. Fish and rocks came hurtling past, and any sand we disturbed was quickly swept away.
After 20 minutes of struggling against the current we decided to exit, and return the next day at a different state of tide.


On the following day we dived three hours after high tide, hoping that this would be the slackest time to dive. Flow out of the cave

however was not reduced; we managed to lay around 50 metres of new cave line into the cave and must have been close to the exit but again were turned around by the current. We walked over to the lakeward side and quickly located the entrance by following the flow out of the lake.

Advanced Course at Sail Rock

By , 12 October, 2011, No Comment

This week I was fortunate enough to take an advanced course to Sail Rock which is widely recognised as one of the best dive sites in South East Asia. It was a fantastic day all round, not only did we experience great conditions but I was with an excellent group of students which enabled us to have a couple of long, relaxed and spectacular dives. Sail Rock, as it sounds, is a great big rock which rises from the ocean floor and breaks the surface about two hours away from Koh Tao.

One of the main features of this dive site is that it has a coral ‘chimney’ which starts at around 6 meters and you dive through it to an opening at about 18 meters deep. It is an ideal site for an advanced course because apart from offering depths of up to 30 meters, it also has an amazing amount and diversity of aquatic life. On our dives this week we saw huge shoals of barracuda, trevally, big eye jacks, queen fish and giant groupers as well as thousands of other smaller species.

Everybody enjoyed the day trip, not least myself and my awesome divemaster Lucy, with cracking weather, great visibility and no waves at all.  All my students, Simon, Nanna, Chris and Adam had an amazing course and all are still diving here at DJL and we are all now looking forward to the next trip to Sail Rock!
