Dave and Adrian managed to get away for a club dive relatively early on, and visibility was good to the south of the pier. We ourselves eventually got kitted up after a lot of mucking about with cylinder fills! There was a wedding on at the hotel which also choked up the car park, and Elliott was getting rather hot in his semi-dry. It was Elliott's first ever sea dive and Jade's final Ocean Diver lesson - leading the dive. I constructed a plan that would fulfil both OO1 and OO5 requirements, getting Elliott to do some simple drills at shallow depth before Jade lead the dive to a greater depth.

After letting my wife (dive marshal, keeper of the diveslate) Jen know our air and time in, the fishers on the pier know we would be swimming around the base of the pier before descending, we entered via the steps where I felt the biggest leak in my drysuit I have ever had. Becky on surface support checked my drysuit zip but it appeared fine. I thought my dump valve was letting it in, but it seemed to taper off within a few minutes so I thought no more about it.

We circumnavigated the pier avoiding all the fishers and descended to the base, a depth of around 2m. Elliott did a good fin pivot, it seemed he had the correct weights at the time. Jade then buddied with Elliott and lead the dive with myself behind, with the intention of using the rock wall as a navigation aid, but the silt had been stirred up rather rotten and at times all I could see were the end of Jade and Elliott's fins. I was keeping an eye on our direction with my compass, which Jade did not have or anticipate needing. Jade turned round and signalled to surface so we could get a look at where we were. We were a far way off the wall and about 150m away from the pier. We gained our bearings again and started to go down again but Elliott had problems equalising (popping his ears). We surface swam back to the pier where I suggested we complete Elliott's mask clear drills but he was uncomfortable, so asked if he could get out. This was no problem and probably a good idea, as noone should dive if they are uncertain or uncomfortable, as this could lead to major incidents.

Becky helped Elliott back to the car park while Jade lead the dive back from the pier to the shore, which gave her more of an opportunity in clearer water to check my air, check I was okay and generally navigate to the shore which was successful  At chest depth we did a low-air buoyancy check which was fine, and finally Jade jettisoned her weightbelt to complete the lesson.

Place: Babbacombe, Torquay       Buddy: Becky H, David C
Time Down: 1515                         Dive Time: 00:31
Time Up: 1600                               Max Depth: 4.3m

The second wave was later getting away than planned but it was mid afternoon and noone seemed too rushed. My wife had to take the boys home so Jade looked after the dive slate. We planned the same lesson, but the tide was a lot lower, almost at low tide, and the best bet at any visibility was in the bay where Jade and I found it to be a lot clearer previously.

Elliott kindly lent me his semi-drysuit (I have never worn one until today!) which I managed to squeeeeeeze into as my drysuit was incapable of being a dry suit. We stumbled over rocks and boulders to get to the water's edge to the amusement of everyone watching from the beach and cafe! We did buddy checks and Becky have a good brief to David as part of her exercise. The plan was to use her brand new compass to navigate in a straight line out of the bay, turn round after 70 bar (one third) of our air had been used and come back on the reciprocal bearing. 

It was difficult putting fins on in such shallow water so we instead put helped each other on with fins slightly further out. The seaweed was a nuisance as well. We didn't get a very inspirational depth but it was sufficient to stay underwater. David was on the light side of neutrally buoyant when doing the fin pivots, but otherwise seemed comfortable in the water. Becky did a good job leading the dive, checking David's air and that he was 'okay', but found the compass a challenge. This didn't impede on the lesson (aside from ending up at the same dead end twice!) as she took assertive corrective action when she realised the error, and directed David accordingly. Becky signalled that David had finished his first third of air and lead us on the reciprocal bearing back to the shore. Visibility was slightly better, but not as good as earlier. Certainly not the most inspiring dive where marine biology was concerned, I saw a few dead crabs but nothing else of interest! Towards the end of the dive the partial-flood mask clear drill was carried out, Becky maintained a mid water hover on low air at 2m depth, and finally when they were chest deep they both jettisoned their weightbelts. I picked up both weightbelts and unfortunately this caused my compass to slip off into the silty seaweedy tidal waters. I hope someone finds it and has many an enjoyable and memorable dive navigating with my compass! 

The best moment of the day however was watching an overloaded motorhome trying and failing to leave the steep sharp bend on the hill out of the carpark!

Babbacombe, Torquay

Date: Sunday 30th June 2013          Dive Number: 168
Place: Babbacombe, Torquay         Buddy: Andy P 
Time Down: 1100                           Dive Time: 01:00
Time Up: 1200                                 Max Depth: 8.0m

You can see the remains of a crumbling house from Babbacombe Beach. It was bought for £150,000 as a holiday home. The buyers thought that was brilliant, so rushed the sale through without thinking about getting a survey or even going down to the bottom of the garden. After the price, it may have been the view that really sold it to them. How ironic.

It was a glorious morning. The sea was flat and the strong sunshine was breaking through the thinning stratus. Dogs were running after tennis balls on the beach, cars were shuffling into parking spaces and the first cups of tea were being purchased from the cafe in between strategic organisation of plastic furniture on the promenade, ready for a roaring day's trade. One diver came up to me and asked for his drysuit to be zipped up, which I duly did without questioning. He will appear again later, so keep reading!

The rest of our contingent arrived soon after myself, Linda gave a short brief and assigned buddy pairs. It took no time to kit up, no piece of kit had been left at the house and everything seemed to work, so we were ready in minutes. I took the decision not to wear an undersuit on this occasion, but settled for a rash vest instead. 

After buddy checks we made our way to the pier steps, stopping on the way to let the fishermen know our plan. Apparently they were more concerned about a solo diver who had gone in moments before, and not told them what he was doing, where he was going and had no surface marker buoy. Naughty. We slipped off the bottom of the steps and surface swam round pier under the fishers until we were clear of lines. I found if I swim on  my back a jet of water shoots down the back of my neck, and possibly through the armpits of my drysuit. I seems drier on my front with my arms tucked in. I reckon I could get away with a few more dives before thinking about having it repaired.

Visibility was about two or three meters initially, we saw a few wrasse and spider crabs to kick us off. At a depth of three meters and soon after I spied an edible crab, a dark shape loomed out of the silt and plankton carrying a high powered torch, illuminating all the interesting rocks and  seaweed below him. He signalled okay to us and disappeared, no buddy in sight. Andy and I exchanged glances - it was the diver who I met in car park, the one the fishers were annoyed about. Some people have no sense, even if it is only a shallow dive. We pushed on against the weak current and up to the swim-through where visibility dropped to near zero, as plankton had accumulated there over the past few weeks. The wall was like a ghostly dark shape and was the only datum that I had, I even had difficulty keeping Andy in my sights. Soon after clearing the swim-through visibility improved again and I spotted a (or 'the') cuttlefish, which help two tentacles up to me, so I reciprocated by giving him two fingers. It's probably a sort of cuttlefish gesture. 

Not much was spotted after that, I did note that the spider crabs were a lot bigger than I remember, some of them seemingly had bulging biceps! We turned round at about 130bar and swam back towards home. It was a lot nicer on the ankles as we were now swimming with the current. We saw more crabs and wrasse, and plenty more plankton. Then, out of the murk we came upon the other buddy team at an oblique angle, which lead to a brief moment of confusion and hilarity as buddy pairings got mixed. We left them to it and I followed Andy's direction to try find the end of the pier. At one point Andy stopped and searched among the seaweed, but found nothing (he later said he though he saw an octopus dashing for cover). We overshot the end of the pier and swam through the stringy seaweed for about fifteen minutes before surfacing right in the middle of the bay, almost in exactly the same place (and for the same reasons as) the dive with Steve G's last year!

Here's the log entry for this dive. No sketches I'm afraid, I got carried away with writing!
