Welcome to the Boonsung Wreck
The most important part of the dive is finding the wreck. There are several buoy lines attached to the wreck and you should use them. If you do a free descent with nothing in view then you may get lost fairly quickly. Descend down the line until you can see the wreck and then keep it in sight for the entire dive. Navigation is easy as long as you stay near by.
As you descend you will likely be greeted by the massive schools of snapper, fusilier and barracuda. Spend some time just swimming around inside the ‘Fish Soup’. After a while descend to the bottom and then continue to navigate your way around the wreck. The easiest way to get around is to follow it around either clockwise or anticlockwise. This way you finish in the same place you started.
If you swim at a fairly slow pace you will get all the way round the wreck in around 45 minutes. If you have two dives here then slow down your dive to a nudibranchs pace and give yourself more time to search for all the macro life. Do not penetrate the wreck at any point. The structure is not stable and this could be dangerous. Stay on the perimeter of the wreck.
Be careful of your buoyancy and watch where you are kicking your fins. Lots of old rusty metal and marine life including hundreds of scorpionfish, lionfish, sea urchins and more can all pose as hazards. Also, try to keep your fins off the bottom. Kicking up the sand can reduce the visibility and spoil other peoples dives.
One of the best parts of the dive site is known locally as ‘Nudibranch Hotel’. This large section to the North West is home to dozens of species of sea slugs and nudis. However, you will need to have a keen eye. Several of them are brightly coloured but other are camouflaged very well on the rusty metal surface. A nudibranch enthusiast could spend the entire dive on this one section of the boonsung wreck.
As you come to finish your dive it is nice to spend a few last minutes swimming inside the giant schools of fish. Then as you ascend, swim away from the wreck. Make sure someone in your group has deployed a safety marker. Sometimes the dive site can be busy with both Similan Liveaboards and longtail boats doing day trips from Bangsak beach.
