Dive sites explained – King Cruiser

King Cruiser  Dive Map Kon-Tiki Diving Thailand
King Cruiser sank on the 4th of May 1997 after a collision with Anemone Reef, a well chartered pinnacle. All passengers escaped on life rafts and picked up by nearby diving and fishing vessels.

The ship is a rebuilt, 85 meter long catamaran type, car ferry that was carrying passengers between Phuket and Phi Phi Islands and now stands completely upright at 32 meters of depth. During the years, she has rusted away and collapsed into a fantastic artificial reef, filled with gorgonians, soft coral and large schools of fish.

Access to the wreck is from a mooring line secured at the stern at around 18 meters. Due to the current, sometimes low visibility and the deep average depth, to really enjoy this dive you should be a comfortable advanced diver.

Highlights

  • Right below the mooring at the stern you can find several toilets, still intact. This calls for some very interesting underwater photo shoots.
  • Following the stern towards the starboards side you will find a huge propeller, half buried in the sand. This is also one entrance to swim the whole length of the ship under the hull.
  • In the bow of the ship you can still find paint on the inside of one of the hulls.
  • Due to the depth, Nitrox is a great way to extend the bottom times. For double cylinder tec40 or sidemount divers, there are great rewards for having a deeper profile as you can stay away from the crowd and have time investigating these parts.
  • The wreck has such an abundance of schooling fish, which in turn are hunted by larger predators. Here you have a great chance spotting huge trevallies as well as leopard sharks on the bottom and other passing pelagics.

To think about

  • Currents can be very strong so the mooring line should be used during both descents and ascents. As King Cruiser has many visitors, the line gets crowded at times so here we make sure to be considerate.
  • There are still many swim troughs along the wreck that calls for some caution, as the rusty edges of the wreck are extremely sharp.
  • Keep a close eye on the computer and gas supply as the average depth is usually deeper than 18 meters.

depth:               18 – 32 meters
current:             moderate – strong
visibility:            10 – 25 meters

You can dive King Cruiser from our dive centers in Phuket, Koh Lanta & Krabi

TIME high school abroad – The internship continues

monkeys on ao nang beach diving krabi thailandHello again.
It’s time for another post from our adventure in Thailand. We forgot to introduce ourselves properly in the first post, so we will take the opportunity to do it now.

Our names are Marcus, Alexander and Erik, as we mentioned in the post before we are from Karlstad International TIME program which is an upper secondary school in Sweden.  We have been educated in IT, media and entertainment enough said.

We have now spent one week here in Ao Nang, Thailand, with Kon-Tiki. We have been working from Monday till Friday where we have been helping Niclas and Martin with a web project. We have been designing buttons and working with menus for the website most of the time. One of the main goals with the webpage is to make it more accessible for mobiles as well. As I mentioned, we have been working a lot with the design.

Last week we hired scooters to make things easier for us here in Ao Nang. Our hotel is situated between the office and beach, in that way it takes some time to travel between the places. Using scooters make things much easier and cheaper. When we have finished work on the weekdays around 5 pm, we take our scooters down to the beach and get ourselves a swim. The weather has been most of the time great, so taking a swim is a great way to cool down and the beach is beautiful here in Ao Nang.  Some of the days we have been on the streets of Ao Nang and checked out the local shops.

At Wednesday we were on Discover Scuba Diving trip with Kon-Tiki, you can read more about in our first post. Otherwise our days here Thailand have been kind of similar, working on the webpage in the office with Niclas and Martin. We had free time on the weekend. At Saturday it was raining a lot but we went down to the beach anyway. Near the beach at the southern side, there’s a national park where monkeys live. It’s a staircase that Monkey at ao nang beach diving thailand leads along the mountain and through the jungle. In here you will meet pack of monkeys and be careful because they might steal your belongings, especially if you bring food with you. Actually they tried to steal my bag with a pair of pants in it. We visit them both Saturday and Sunday to get some nice photos of them. At the weekend we have also tasted a bit of the night life here in Ao Nang.

In week number two we will be starting our PADI Open Water course and after work we will have lessons in diving at the office. On Thursday morning we will be in the pool to practice the important parts in Scuba diving and after that we will make our dives. But more of that later!

Our time in Thailand has so far been very good, the Kon-Tiki-staff have been very welcoming and they are taking good care of us. They help us a lot to make our staying in Thailand as good as possible.

See you around!

Why combine Sidemount with Nitrox?

Nitrox giant stride sidemount diving thailandFor a regular diver making an average dive on a single (12 litre) cylinder will usually be able to make an hour time underwater. This will decrease substantially when diving deeper or in a current, where you quickly will become restricted by your gas supply.

A way to accommodate for this build-up of air consumption is to increase your cylinder size. This by using a 15 litre cylinder or choosing to dive with doubles. However, finding this option on your dive travel or holiday is not always easy.

When we dive with sidemount configuration we usually dive with two cylinders. Not only will this double up your gas supply, but “normal” size cylinders are used everywhere, making it great way to make longer dives on your holiday.

However, diving longer and deeper dives on air is not always a healthy option. If you are making several dives during the day or spend great time at depth on a wreck dive, your nitrogen load might become an issue.

By switching gas in your cylinders to Nitrox or Enriched air we can almost double up the bottom time, due to the lesser nitrogen. Combine this with two cylinder sidemount, you have the perfect recipe for longer, deeper dives on your favourite spot.Nitrox surface sidemount diving thailand

Narcosis – diving deep has a price

Deep diving thailand koh lanta nitrogen narcosis

Nitrogen Narcosis or “raptures of the deep” is an altered mental state caused by the increased pressure of gas in your body. Most divers will start getting affected by this sensation around 30 meters, and the effects will increase by depth.

Most commonly we dive on normal compressed air, comprised by mostly oxygen and nitrogen. Due to the large amount of nitrogen, this gas has the largest impact on narcosis as we descend. The concentration of nitrogen impairs the conduction between our nerve impulses, which resembles the influence of alcohol. As we go deeper the pressure increases, with that the narcosis starts affecting our mental abilities.

Just like drinking small amounts of alcohol, the narcosis itself is not harmful. However, being under the influence 30 meters under the surface can lead to accidents, the same as driving a car intoxicated could. Unlike other drugs the narcosis subsides quite rapidly as the diver ascends, and pressure decreases.

The symptoms of narcosis is the same as anesthetic drugs, causing the diver to feel symptoms like dizziness, euphoria, slowing of reaction time, loss of dexterity, perceptual narrowing, numbness and amnesia.

As the diver continues to dive at this depth he will go through series of different mental states. This includes going from a relaxed, euphoric and overconfident level to a sensation of panic thoughts and terror. This means that a diver, who has experience of making short deep dives, will experience something completely different when staying down there for a period of time.

There is also a general belief that predisposing factors like cold, darkness, clear blue water, sea sickness and hard work underwater has great effect on the severity of the narcosis. A diver, who shows no signs or symptoms on a deep dive one day, can experience narcosis on another.

Divers sometimes believe they are not affected by narcosis after a dive, but this can simply be because the symptoms where disguised by task loading or other factors. Just as a person can think he is not affected by having a couple of drinks. Diving deeper than 30-40 meters will produce some kind of narcosis, the symptoms might not just be as visible.

There are two ways of preventing narcosis. By keeping above 30 meters, you should stay relatively symptom free. The other way is to mix helium, a less narcotic gas, in your cylinder. This will make deep dives more manageable, however mixed gas diving requires some additional training and equipment.

But by managing narcosis, keeping up to date with your training and staying physically fit, you can experience some of the most mystical places on earth.
