A busy Saturday in Kilkee, where i did dry cox fro our diving club.
View from the boat of the dive site ( Middle Rock ) , we used the Lought Dergh in the morning, after having stuck our in the sand by stubbornly trying to launch at low tide.

It was a beautiful sunny day in Kilkee, and the place was busy, in particularly because the great swim was organised that day. Anyway our plan was to go diving, with a very low tide at noon, we planned to launch our boat at 10AM.
We were all ready for the boat launch on the slip around 10, but we decided to purge on refill the hydraulic steering wheel of the boat first. This operation took a lot longer than the 10 minutes initially planned, and it resulted in a very slippy boat covered by oil. Off course by that time the water had almost reached it's lowest point in the pier, and we had to try launching the boat with a rope ; after 4 attempts, we managed to have the boat in the water and out of the trailer, only to find it beach on a sand bank in the middle of the pier.
There was no way we could drag the boat for 10 meters over the sand until it reaches enough depth.
So we threw an anchor ( so it would not drift on shore once the tide was rising ) and borrow our friend from lough Dergh boat to go diving.
We settle upon Middle Rock as a dive site, with 1 hour delay to the initial plan.
Sadly it was not the end of our misadventures. A threesome of divers had an equipment issue - one of the guy's regulator went on free flow and refused to give air, forcing the three of them to air sharing, and aborting the dive. It resulted in an uncontrolled ascent , sightly faster than recommended - well depending on which table had been used, the rate could have been bound safe - a
h the good old navy tables ( 9 meters per minutes ).
Unfortunately for me as a cox, they surfaced in the worst possible site over middle rock, right where the waves are breaking on top of the rock. I collected the 3 boys, not without having to drag them with the boat out of the danger zone. One of them was feeling a bit unwell and was put under O2.
We then proceeded to recall the other divers, without any success, despite revving the engine and banging cylinder underwater.
After 10 minutes, they finally surfaced, and once everybody was on-board we headed to the pier. Once there we called the coast guard for advice, and soon the problematic party was rush to the Kilkee rescue center for examination and all 3 of them were put under O2. They were evacuated soon after to Galway by helicopter ( the helicopter came to Kilkee for another emergency, and it was decided to use it to transport all causalities ).
Once in Galway the boys were put in a re-compression chamber and put under observation before being released late, all safe and sound.
With nothing left to do, except checking by phone on the lads progress, we decided to go on with the afternoon dive. By that time our boat was afloat ( finally ), thanks to the rising tides, and a group of 7 divers headed again for middle rock, and once again I served as dry cox.
Once again we did not escape incident, but it was more minor, one of our diver had its high pressure hose blow up on the boat, and as a result did not enter the water - which was as well as i had an helpful hand for what follow, as one of the pair aborted the dive early due to high PPO2 reading on a rebreather.
Anyway after all that stress, everybody was brought back safe and sound on the shore, for those who did dive, they had a lovely one - well that's what they said despite the puking on the boat afterwards.
And that was all for the day, best thing was to head to the pub, have some food, and welcome back the boys from their escape to Galway.
Some key lessons from this:
- Direct system horn, which was very helpful to signal and call for help, without the lads blowing it, i would have reacted much later.
- Dry cox: it has the advantage to speed up the dives, avoiding for people waiting on the boat ( in case of 2 sticks ) while over are diving - either before or after their own dives. But in case of emergency, the cox is busy driving the boat, and cannot take care of the diver at the same time. I would highly recommend to have 2 people on the boat at all times.
- Recall: there is a need to find a proper recall procedure for diver underwater, revving the engine did not work - but maybe I was to gentle with that - banging piece of metal underwater did not work either ( which i thought would ).
- The importance of working mean of communication with land ( either VHF or cell phone )
