Comments

An evening boat dive of diving club Kupla with Hinkki boat.
8 divers: me, Jouni, Mikko V, Ville, Markus, Juhani, Tommi, Tomi.
Mikko and Tommi had CCRs.
We left harbour almsot at planned time at 17:40. We decided to go to Coolaroo again.
I was driving the boat to , Tommi navigated for me.
We arrivied to the destination quickly in nice sunny weather at 18:30, there were very small waves, very light wind.
There was a bigger buoy attached to the bow part of the Coolaroo wreck, so we moored the boat on that, and were able to start diving immediately.
Me and Tomi went to water first. We agreed on 45 min dive time.
Our plan was to go aroud the bow and if the visibility would be bad, then also go to the engine using the guide line.
The visibility was not so great, so we dove first on the board (left) side deck, then from the bow down to the anchor at bottom, then along the starboard (right) side towards to rear side. From there at 25 min we followed the upper guide line to the engine, and circled the engine and the debis field around it until 40 min. Then ascended on top of the engine block and to surface. Then swam on surface back to boat.
Water temperature was 6 to 7 degrees at the bottom, near the surface 9.

Ville had broken neck seal on his dry suit, so I borrowed my suit for him, so he and Jouni could go diving as the last pair. When Ville and Jouni returned, we drove back to shore and refuled at Lauttasaari. Back to Otaniemi at 22:00.
