Saturday 18th March 2017

It’s 4:00pm and guests arrive to Thailand Aggressor by dinghy from a very busy Thaplamu Pier. Our helpful crew shows them to their cabins and help to set up dive gear on the platform. After a general boat briefing the Thai crew lights off celebratory fire crackers on the bow as is Thai tradition for good luck before setting sail. The chef prepares a three course Thai dinner and we are off to the Similans for our weeklong diving adventure. Welcome Aboard!

Sunday 19th March 2017

An early wake up of 6:00am allows our guests to enjoy a beautiful sunrise while they have a light breakfast. After a dive safety briefing we gear up for our checkout dive at Zodiac. This site features over a dozen sunken statues symbolizing the twelve zodiac signs. Guests enjoy the crystal clear visibility here and at also the next spot, Anita’s Reef. At Anita’s Reef we go to check out ‘One Roll Rock’ which is teeming with life as always. This rock is home to a variety of creatures including clown anemone fish, thousands of glass fish, several nudibranchs, and tiger cowries. After lunch we head to Island 7 where we dive Deep Six and West of Eden. Our divers loved the swim through at Deep Six with its bright Gorgonian sea fans and many schooling banner fish nearby. One both dives we got to experience up close encounters with green sea turtles who were not shy around the divers, and carried on munching away on the corals. After a chicken parmesan dinner most guests decided to relax on board while a few others went on the night dive at Hideaway Bay. It has been an awesome first day of diving, and our guests can’t wait to see what is in store for them tomorrow.


Monday 20th March 2017

The day begins at Shark Fin Reef, named for the shark fin shaped rock which protrudes the surface at the site and, coincidentally, is home to several sharks. Today, we are excited to spot the white tipped reef shark swimming along the reef. Next we head to a deep site called Boulder City. The divesite is a huge area of granite boulders that is completely submerged. Our guests had a very nice treat in store as on the desent we spotted a Leopard shark of out in the sand we also saw Barracuda and some unicorn fish out in the very blue water. We cast off our mooring and headed up to Elephant head for our 3rd dive this is a great divesite with swim thrus in abundance we encountered a lone barracuda and also some giant Trevally. On our safety stop one of our guides found a blue dragon nudibranch crewling up the vertical face of the rock, the weather had changed a bit so we headed around the east side of island 9 this is a dive site that runs the whole length of the island we hoped for some current so we could drift but it was only slight so we took the reef really slowly we found a turtle munching on some corals and also many large trigger fish nesting in the sand, they were quite defensive of their nests and charged anything that ventured too close. We headed back to Beacon reef for our night dive and saw a free swimming moray and a couple of large coral crabs, after the dive it was movie night on Thailand aggressor and we enjoyed a big bowl of popcorn and a great movie.

Tuesday 21st March 2017

The weather was still changeable this morning so we decided on the sheltered side of island nine and headed to a dive site called Christmas point this dive site is named after the amazing amount of Christmas tree worms that scatter this site, our guests were fortunate today and saw a white tip reef shark and also a huge great barracuda that has been living at this reef for a few weeks now, also encountered at the safety stop we saw a Napolean wrasse down in the deep. We moved the short distance to 3 trees again for our second dive and as it was one of our early dives we headed to the outer reef this area is dominated by a huge sea sponge about 5ft tall it’s a great spot for our photographers who snapped away with buddys in shot. Our 3rd dive would be at north Point the most northerly of our sites within these 9 islands, we found many reef fish in abundance including a school of sweetlips also we searched for our special find here this is a pygmy pipehorse, it had moved slightly and also another couple had turned up these critters are so small it’s a hard find, our guests enjoyed seeing a turtle off in the distance. The weather had improved so we headed up to koh Bon this ridge is famous for its manta ray action so after our special manta briefing we descended we did not encounter these awesome fish but we did have a great dive with much hunting action going on and also on our night dive we found Spanish dancer eggs and a octopus out hunting.

Wednesday 22nd March 2017

So our first 2 dives today would be at koh bon one at the pinnacle and one at the ridge we elected for ridge first as we had seen another boat heading for the pinnacle we placed a line on the divesite for reference on our descent and off we went there was a small school of barracuda along with some schooling bannerfish there was a lot of marine life swimming out in the bluewater. So off to the pinnacle we headed this lays around 400m north of the ridge its very deep water all around these twin limestone pinnacles, the action started as soon as we submerged with golden trevally circling and some yellowtail barracuda out deep, we also found some nudibranchs. We cast off the mooring after lunch and headed for Koh Tachai island, this island is the most northerly in the Similan marine park and one of our favorite sites, this is also a granite pinnacle off the south tip of the island we saw the resident school of barracuda they were in their hundreds today and all seemed to be swimming with no effort just cruising the shallows for the next meal. The current was not to strong but for our final dive of the day we aimed for koh Tachai reef, we were treated to a fly by swim of a large blotched fantail ray, also seen was a kuhls ray and a large giant moray was out foraging the reef. We were headed for Richelieu rock in the morning so after dive 4 we moved to the Surin islands and had a delicious Japanese themed meal on the way then for the people who wanted to stay up late we had a new movie one of our guides had aqquired.

Thursday 23rd March 2017

Richelieu Rock today, we had a small lay in bed as we had scheduled our first dive at 8:30 am our cruise was only short but we headed straight into the sunrise which was a great experience. For our first dive we decided on a visit to the northern pinnacle on the outside here is a very special find for our region, a Thorney seahorse yellow in color has seemed to set up home here and has been in the same spot for the last few weeks and true to form it was still hanging out in the same whip coral we saw many other fish hunting and also a group of 7 lionfish. On our second dive we headed to a western pinnacle where we also had a special find, a couple of ornate ghost pipe fish are in a crevice here this pleased our photographers immensely, On the3rd dive we stuck to the main pinnacle and found a group of 6 flabalina nudibranchs all feasting on the same Hydroid also seen was a school of yellowtail barracuda along with some hunting jack fish. Our last dive of today at Richelieu rock we decided to explore the inner part of the horse shoe shaped formation we saw a tigris cowerie and not so far away was a group of banded boxer shrimp, We upped anchor and departed from Richelieu and enjoyed a nice sunset meal on our passage back to Koh Tachai….

Friday 24th March 2017

After a good nights sleep we were up nice and early, we decided to dive at Koh Tachai pinnacle again, we had a great dive here earlier in the trip and our guests got kitted up and we headed off to the pinnacle in the dinghy, the current was very mild which was unusual at this dive site. After our descent we encountered a huge school of yellow and blue fusileers the barracuda also made an appearance along with a small school of snapper the current picked up a littlebit during the dive so we did our safety stop on the drift. Our second and final dive we headed back to the pinnacle . The barracuda were circling the dive site again along with huge giant Trevally what a great action filled dive we had enjoyed. We all completed our safety stops then headed back to Thailand Aggressor we cruised back to our home port ready for our end of trip BBQ and video.

Saturday 25th March 2017

Some of our guests this week had early flights so departed early after a full cooked breakfast, we said our goodbyes and thank you to all our crew. Our second group left some 45minutes later and we wished them safe travels.
