Avoiding Decompression…

11 Jan

Waking up at 6am every morning due to the glorious sun shining through my window is one of the best things ever. The boys were still asleep and I tiptoed out of the bungalow so as not to wake them…especially Willy all wrapped up in the hammock like silkworm in it’s cocoon.
Thailand (149)

Assisting the French

Today the shop had 3 French students doing their Open Water Course and their first ocean dives. In cases where we have students with a language that is not covered by the instructors at the shop we hire in a freelancer. I think being a freelance dive instructor would be a great way to have a dive career, especially if you have another skill that can be used to fill in the financial gaps between dive jobs. Shops call you in and you can either decline or accept without the pressure to take it as it is your place of employment. But again, you must either be in high demand, have another skill or be financially independent otherwise you could go through long stretches of ramen dinners.

Richie, our freelance French instructor, had me help him with his dives today. As soon as we reached Sail Rock he sent me in first to go set the float line. I had done this once before and was still mastering the strangely difficult task of getting it tight enough. If it is too loose then it could get caught up on the coral or tangle with another line, if it is too tight and waves develop it could be yanked off taking the chunk of rock with it and causing damage. Swimming out to the rock and dropping down at the appropriate spot I just hoped that I would drop down where some of the tie lines were. CORE SEA, a local non profit studying the coral and working to protect it, had set these nifty loops at certain intervals around Sail Rock. Of course there are always the days where the current forces you onto the less frequented side resulting in a difficult search for a spot to tie the line. Luckily, this was not one of those days and I managed to find a tie line and tie it up. Of course, even though I had battled to pull it as tight as I could with the surge constantly pulling it from my hands, I discovered it was still too loose. Luckily it was ok for the students to complete their skills and when we dropped down I was able to quickly retie it tighter.

I was buddied with the 3rd member of the trio and he was a dream student. Completely natural in the water and no issues what so ever. If I didn’t know better I would have thought he dove before, but he swore he this was his first time… I bet you that’s what they all say 😉 . The other 2 however, were not as dreamy. In fact just after we dropped down, less than 5 minutes after Richie had explicitly said not to touch anything, one them got my attention and pointed to his hand. I saw around 5 small puncture wounds trailing blood in what appeared to be a sea urchin inflicted wound, as if he had tried to pick one up.. on the surface we discovered that is precisely what he had tried to do. I guess he didn’t realise they are just as prickly below the surface as they are above!

Prickly, definitely prickly!

Prickly, definitely prickly!

On the up side the dive was pretty good. There were tons of large groupers everywhere and we saw 3 scorpion fish, the most I had ever seen in one dive. The students all seemed happy when they came out and enthusiastic for the next dive.

As I clambered aboard, Marc told me that he needed me to dive with his group on the next one as the male half of his couple had “sucked” his air. This means that he had breathed too heavily and depleted his air much faster than expected, in fact he was down to the limit after barely 20min. With only Marc as a guide he could not send the guy to the surface alone nor could he leave the wife to dive alone. So he had been forced to return after a very short dive. Most dives last at least 40min.

Avoiding Decompression

Marc planned to drop back down within 20min, which would give me around a 40min surface interval instead of the usual hour. In these circumstances you have to keep an eye on your computer to watch your time for DCS (Decompression Sickness). Most computers will tell you how many minutes you can remain at a certain depth before the risk of DCS, and as long as you move to a shallower depth and be sure to surface before these numbers are too low then you should be fine.

I ended up having almost an hour but to be safe I dove a few meters above them and thoroughly enjoyed just hanging out…literally. 30min into the dive Marc signaled to me that the husband was down to 50bar, the minimum preferred amount of air to surface with a 3min safety stop at 5m. Acting as calm and professional as I could, this was the first time I was taking a diver back to the surface alone, I guided him back the way we had come hoping I would surface at the right spot. We hung out at the 5m mark, all the time keeping my eye on a rope I hoped to heck was our boat and not a Burmese fishing vessel on the other side of the rock. When our 5min were up we surfaced and, just as I had expected…., there was the boat (thank the heavens!)

All in all a great day and I liked the feeling of the responsibility of taking the diver to the surface and tying the float line.

Introducing the Local to the Surfers

Back home I studied my dive books and waited for Willy and Daniel my two couchsurfers to return from their escapades around the island. After a few hours I went to fill Lucy Liu bike with gas, the farthest I had gone on my bike. A full 5min away from home. When they weren’t home by 6pm and I was famished I popped down to my local and got some of my favorites.

Reclining in the hammock, reading and killing mosquitoes while periodically watching a great episode of gecko tv on my wall, they arrived, it was barely 7.30pm and they felt bad I had waited. But it was all good and I took them over where they bought me a beer and told me about their day while eating. Both of them are huge foodies and could not believe how good the food was. They planned to come back the next day, Willy with his notebook to take down how to cook all the delicious dishes.

The rest of the evening was spent relaxing and planning our adventures for the following day. At the boys encouragement to improve my driving, I had decided to take the day off and attempt to drive all the way to Tong Sala, a full 20min. Mmmm this could prove a make it or break it moment in my bike driving career…

    I always struggled to find the boat again above Sail Rock – one time, with a pair of Danish students, I brought them up on the opposite side from the boat – coz of the current we’d done an extra half a lap! Man, that was a LONG surface swim to get back to the boat… and by the time we managed it we were so late that my boss missed his visa run! D’oh. Was I ever i trouble that day… :0)

      Tony I am truly amazed how you seem to get in trouble at least once in everything you do, a real talent I think. I can only imagine how annoyed your boss was, as most people wait till the last day to the visa run… As far as currents, I hear ya, we had a couple of days over full moon where you jump in and pop up half way back to the island and that was before the dive even got started.
