A tin dredger called Boonsung sank around 20 years ago.
It is located to the west of Bangsak pier, about 7 nautical miles offshore or about 13 nautical miles away from Tap-Lamu pier.
It is a favorite destination for day trips that depart from Khao Lak. The wreck lies on serene flat sand at 18 to 20 metres.
The wreck is around 10 metres wide and 30 metres long. The average roof level of the wreck is at 13 to 16 metres long.
After the tsunami, the wreck has been broken in 5 to 6 parts.
All are fully covered with barnacles and sponges, and only a few corals can be seen here.
Sometimes you can see the remains of a fish cage near the wreck. There is a small buoy which the daytrip boats use to moor.
Current:Mild to moderate.
Marine Life:
Although Boonsung wreck is a small site, tones of fish gather around here,
such as schools of bigeye trevally, snappers and batfish.
Also big schools of porcupine fish and squid can be seen lingering around.
On the sand floor, you can often see leopard sharks, a variety of gobies, and tiny flounders and flatheads wedged in the sand.
Hiding beneath the wreck in the dark, divers have often seen huge marbled stingrays.
On the wreck itself, you can find a great selection of nudibranchs that brighten up the dull wreck.
Moray eels, including white-eyed morays and honeycomb morays with spectacular patterns that are rare at other sites,
can be seen here emerging from almost every crevice.
Cuttlefish, octopuses and pipefish can also be seen.
If you are fortunate enough, you may encounter a whale shark, especially in the month of March.
This tin dredger wreck lies not very deep, and is not too large to explore overall.
However, it’s quite difficult to look into every detail, so try to explore at a slow pace.
You can start the dive at the outer sand area and come back to the wreck, but make sure to explore around before going up to the top.
Close to the sand bottom, avoid stirring up the sand, as this will lead to unclear visibility.
There are plenty of scorpion fish and lionfish camouflaged on the sand and on the wreck.
Therefore, it is best not to touch any part of the wreck. The wreck has been there for a long time,
