Saturday 31st December 2016

The guests arrive to Thailand Aggressor at Thaplamu Pier by dingy at 5:30pm and are greeted by our smiling crew. There is time to settle in and set up dive gear before gathering in the saloon for a general boat briefing. Chef prepares a three course Thai cuisine dinner, and then we are off to the Similan Islands.

Sunday 1st January 2017

Guests wake up to fresh brewed coffee and beautiful Similan sunrise which sets the perfect backdrop for our first dive site at Island Seven. After a safety briefing we gear up and jump in at West of Eden. The check out dive is short, but very exciting! We start with a quick buoyancy adjustment at the surface then descend into the beautiful Andaman underwater world. The excitement of seeing a free swimming giant moray eel is soon overshadowed by the sighting of a green sea turtle, calmly munching away at the coral, and then a spearing mantis shrimp peering at us from his burrow. Next we head to Anita’s Reef to check out ‘One Roll Rock’, which gets its name from the theory that a photographer could easily use one whole roll of film on this one rock. The site is covered in glassfish; pairs of butterfly fish, cleaner wrasse, and on the sandy bottom are hundreds of garden eels. The guests love this site so much that we spend most of the day here, including the night dive where some divers get to see their first cuttlefish!

Monday 2nd January 2017

The day kicks off with a deep dive at Deep Six on Similan Island Seven. Schools of bannerfish and awesome visibility make for a nice morning dive. Chef makes French toast and eggs ‘your way’ as well as a breakfast buffet complete with fresh fruits, granola, homemade bread, hash browns, and bacon. The guests are all fuelled up and we head to Elephant Head Rock, where the dive masters lead their groups through multiple swim throughs filled with oriental sweetlips and bright gorgonian sea fans. Now for what turns out to be the highlight of the day, dive number 3 at Three Trees. We drop in and immediately see a 2 meter long guitar shark swimming across the sand below us. What a special find! The current allows us to drift along the reef finishing the dive with a photogenic green sea turtle. The rest of the day is spent at Turtle Rock where we also do our night dive and see a marbled ray. Then back to the boat for hot coco and bed.

Tuesday 3rd January 2017

At the most northerly point of this Similan Islands we have arrived to Island 9 for our two morning dives, North Point and Christmas Pointe. Here we find massive stacks of submerged rocks which have come to form scenic, elongated channels and a few small swim throughs. The most beautiful part of the dive was right before the safety stop just 8 meters below the surface when we were surrounded by huge florescent schools of yellow fusiliers whose colors contrasted perfectly with the surrounding blue water. From there we head north and leave the Similans to an island Koh Bon. This limestone islet features a huge ridge which begins at about 50 meters above sea levels and slopes downward into the sea to a sandy bottom of about 40 meters. Its cleaning stations attract some of the larger sea animals and today we were able to see a Napoleon wrasse, as well as some smaller creatures such as a banded sea snake, the Maldivian sponge snail, blue dragon flabelina, juvenile midnight snapper, and a juvenile rock mover wrasse. The night dive was also very nice, complete with scorpion fish, spiny lobsters, and a cuttle fish.


Wednesday 4th January 2017

Koh Tachai is a solitary island located 20km north of Koh Bon. The island has nice white sandy beaches and three interesting dive spots. Today we spent the entire day at Koh Tachai Pinnacle, also known as Twin Peaks, and Koh Tachai Reef.   The first site consists of two submerged pinnacles located south of the island, marked at the surface by two buoys. The southern pinnacle is 12 meters below the surface at its shallowest point and is dome shaped, reaching a sandy bottom of about 40 meters. The eastern side consists of smaller stacks boulders and the southern side in covered in colorful soft corals and sea fans. The top of the pinnacle created a wide flat plain and is covered in hunting trevally, blue trigger fish, huge schools of snapper, and thousands of glass fish. We also enjoy the reef where we enjoy calm waters, two octopus, a variety of nudibranchs, a cuttlefish, and many grouper.

Thursday 5th January 2017

After a good night’s sleep at the Surin Islands, we make our way to Richelieu rock for our first 2 dives today. The current is slack as we enter the water and we almost instantly encounter 4 mating cuttlefish which are drifting in the current as the female lay eggs while being protected by the male. We also find a group of flabelina nudibranchs and a Napoleon wrasse. The current picks up for our second dive and this brings in big schools of trevally and also a few yellowtail Barracuda. Some of the more adventurous divers go deep to have a look at the tigertail seahorse. After the 2 dives we upped anchor to head back to Koh Tachai, the current is minimal at the Northern Ridge and we see schools of snapper and also some large Malabar Groupers. On our night div eat Koh Bon we see a free swimming moray eel and a very large lobster out patrolling the reef.


Friday 6th January 2017

Just two dives today, both at Koh Bon. We are greeted by a juvenile Napoleon Wrasse and also a school of goatfish are cruising the reef. For our second dive we head for the pinnacle that lays 400m north of the ridge, sadly when we got there the dive guide saw the current had picked up so we headed for the north ridge we found a octopus as soon as we began our drift along the reef, we also found a couple of sponge snails these were a favorite find for 2 of our guests. The Napoleon returned at the end of the dive and we made some great video for our guests… after taking care of our guest’s eqpt we packed all eqpt away and headed back to our home port and our special bbq nite…


Saturday 7th January 2017
