After serving us well throughout summer, it’s time to send our big boat in for it’s annual maintenance. That means driving the dive boat across to Chumphon on the mainland where it can be lifted from the water, and required work can be completed.
Since we’re already paying for the diesel, we may as well make use of the journey and check out a few more potential wrecks to the north & North east of Koh Tao!
So tomorrow our first dive will be to revisit the WW2 Schooner wreck, last dived when we located it in August, then continue to investigate four more fishermans marks during the journey across to Chumphon.
The most interesting is a mark which matches closely with a wreck position on one of our old shipping charts. The wreck must be a decent size to pose a potential problem [and thus be of interest] for shipping. We’ve never managed to locate this wreck - hopefully this new fisherman’s mark will help us find it. The chart was produced in 1986 - the survey data which was used to create this chart was probably collected well before that date, so we have our fingers crossed that its an old wreck, rather than a recent fishing boat. We’ll see!
The other marks are isolated but come from a reliable source, which has given us several other wrecks over the last 12 months - we’ll just have to see what turns up.
Dive expedition report will follow. . . .
After a long wait [due to bad weather], at last we’ve got the opportunity for some more wreck exploration off Koh Tao, Thailand.
With wave heights less than 1 metre, we’ll be heading over 20 miles off-shore on our dive RIB to check out a war report for a Japanese WW2 vessel.
We’ve got two independent fishermans marks, located close to a report from a US submarine. If all turns out as we hope, we’ll be making our first deep wreck dive on a WW2 Japanese auxiliary vessel. We estimate the depth to be around 55 metres, so are planning for deep air dives with O2 accelerated decompression. We expect the wreck to be 30 - 40 metres in length.

We’ll find out tomorrow. . . . expedition report will follow!
Following the fantastic technical diving trip that we had to the South China Sea this Autumn, we’re planning a repeat dive liveaboard during May 2008.

There are two departure dates available - leaving late on Sunday 18th May or Sun 25th May - each trip lasting for 5 days.
Planned dives include the HMS Repulse, Dutch Submarine KXVII and Seven skies Supertanker. We’ve planned for two dives per day, leaving from and returning to Singapore.

If you’re interested in finding out more, please e-mail DJL Diving.
The next DJL Diving expedition target is a Japanese schooner, about 100 tonnes sunk by USS Bugara on 24th July 1945.
Taking advantage of the great conditions, we’re going to attempt to locate it in the next few days - we have a fishermans mark very close to the war report location, and expect the wreck to be lying at about 50 metres, so we’ll be tec diving it. This time the target it only 45 minutes from Koh Tao (by RIB), so it’s going to be a bit easier going!
I’ll report back what we find on our blog site!


Together with ‘Worldwide Dive & Sail’ we’re running a 4.5 day / 4 night liveaboard throughout the Chumphon marine reserve.
The diving is great - great mixed coral formations, many fish and lots of turtles. Last week Nereides Diving owner JP discoverd a ‘field’ of seahorses!
But here is the really good news:
Tim has a new mark from one of our contacts on the mainland. It’s likely we’ll be making the first dive on a suspected WW2 Japanese Wreck, north of Chumphon. We expect it to be in about forty metres of water.
We’ll also be revisiting the wrecks we discovered at the end of 2006.
There are still a few places left on the liveaboard - the cost is 17,000 baht. All levels of diver are welcome, as we can give training onboard. If you want to join send us an e-mail on info@techdivethailand.com. Also check out further details by visiting the June Dive Expedition listing.
Watch this space - if we get a new wreck we’ll let you know on this blog (about 22nd June). Fingers crossed
