Saturday 22nd April 2017

With all our guests on board we assembled our equipment and got our guests settled in the rooms, We had our Boat safety briefing and all gathered at the front of boat for the firecrackers and the offering of fruit to the sea gods. After we returned to the salon for a great meal inspired from the north east of Thailand, many of our guests had a long day and retired early.

Sunday 23rd April 2017

Up nice and early we all gathered for our dive orientation briefing that just explains how we dive from the boat and the procedures for logging dives, We headed for hideaway bay for our check dive a couple of our guests had a long break in diving and this shallow dive is a great spot to get back the rusty skills, Our second dive would be in the very south of these 9 island at a divesite called boulder city. One of our groups was lucky and saw the Leopard shark we had been seeing recently, We headed west to Sharkfin reef for our 3rd dive this is a nice easy drift dive, we sighted a small white tip as well as a few stingrays in the sand then on one of the groups safety stop a Whale shark cruised on by wow what a good end to the dive . We headed north for our 4th dive to island number 7 to Deep six we saw many jacks and a school of fusiliers’in the shallows also sighted was a small turtle, Our night dive would be in the shallows at island six and is a nice shallow dive our guests found moray and Lobster, after the dive we returned to hot chocolate and a movie.

Monday 24th April 2017

It’s a beautiful morning as guests wake up and make their way to the saloon for coffee and a light breakfast. We jump at West of Eden and are delighted to find a frogfish in the coral. Photographers enjoy seeing out resident mantis shrimp and take their time to get the perfect shot. Next we head to Elephant Head, which is probably our best spot for swim throughs. Here we see a blue dragon flabelina, a clown trigger fish, many oriental sweet lips, and a yellow ribbon eel. After lunch we make our way to Island #9 for two dives. First we jump in at Three Trees and head out across the sand where we are cautious about the nesting triggerfish. The large patch of colorful coral area includes a massive barrel sponge great for photography. Around the corals we find several hermit crabs, a school of emperor fish and a Napoleon Wrasse. Our fourth dive is at North Point where dive guides take the guests to see the pygmy pipehorses. After a delicious chicken parmesan dinner, we have our night dive then return to the boat for an early night sleep.

Tuesday 25th April 2017

Today we start at island number 9 at Christmas point we descended on the east side which enabled us to drift along the reef we encountered several barracuda and also a white tip reef shark, We heard on the radio that manta ray had been sighted at Koh Bon so we decided to change the schedule a bit and head on up to the island that is about 1 and a half hours north of the main Similan islands, we were not disappointed we saw manta on all 3 of our day dives this was such a pleasure, we took some id shots and checked our data base it was 2 new mantas that had not been seen before also on the dives we found a harliquinn shrimp,there were also a couple of Napolean wrasse. On our night dive we saw a feeding moray and many shrimps and crabs out foraging   on the reef. After the dive our guests watched a documentary fromm the bbc we had some popcorn and headed off for an early night.


Wednesday 26th April 2017

Another beautiful Similan sunrise as guests wake up at Koh Tachai, a small white sandy island with a unique divesite called Tachai Pinnacle. Here, with its unusual currents, many nutrients collect in the water which makes for a beautiful and diverse coral reef system. The healthy corals and sea fans attract a variety of marine life including sea turtles, marbled grouper, huge schools of chevron barracuda, brightly colored fusiliers, a variety of anemone fish, nudibranchs, and trevally. We stay here for two awesome dives and our guests are happy with all the underwater action they see this morning. During lunch we head north to Richelieu Rock for the remainder of the day. This horseshoe shaped pinnacle is home to thousands of marine organisms and there is always something interesting to look at. Today we stay fairly shallow checking out the bay and the top of the rock. Two dives here then we have a filet mignon where guests are finally able to enjoy a glass of wine with dinner as there is no night dive tonight. We are very excited to be spending the day here tomorrow.

Thursday 27th April 2017

Richelieu Rock in an isolated pinnacle east of the Surin Islands. The site is marked by the top of the pinnacle which is only visible during low tide. Forming a horseshoe shape , the pinnacle falls steeply to the surrounding sand bottom at a maximum depth of 35 meters. The south side is a bay slope while the rest comprises of sheer walls, clusters of rock and many tiny caves and crevices. We start the day off right with a deep dive of 32 meters straight to the resident thorny seahorse. Throughout the day and the course of 4 dives we see many interesting and exciting things including a big Napolean wrasse checking out the divers, several banded cleaner shrimps, big school of damsels fish and snapper, tomato clownfish which are unique to this site, peacock mantis shrimp, and many large marbled grouper and for the first time at Richelieu Rock this season we find a pair of harlequin shrimps . It was such a wonderful day, divers are sad to leave, but happy to have the photos and the memories.



Friday 28th April 2017

Sadly it is our last day of diving, and guests are eager to get in the water one last time. We start with a dive at Tachai Pinnacle and enjoy seeing the morning action as trevally feed on the smaller fish. We have a hot breakfast and head down to Koh Bon for our final dive. After the dive, guests have time to relax and fill out log books while crew gladly washes their gear and hangs it to dry. We arrive to Thaplamu at 4:00pm and gather for the seafood barbeque at 6:00pm. After dinner guests enjoy watching the weekly trip video and reminiscing on the weeks events. We settle bills and guests exchange contact information for future travels. Congratulations to our iron divers of the week, who completed all 25 dives!


Saturday 29th April 2017

Well what a week we had this week great guests and some fantastic diving, some of our group saw everything from whale shark to the smallest of marine life such as the very rare Harliquin shrimp. Our guests were great fun this week and we enjoyed many great dives and lots of great stories. This would be our last dive in the north Similan for this season we will head to the south Andaman for our last trips.
