Part of the "Helsingin Helpot" weekend of dive club Kupla
https://kupla.org/int/events/600/helsingin-helpot-coolaroon-kone/
We were 11 divers + 1 non-diver in total, so both 2 boats Hinkki and Irmeli were required.
5 persons on Hinkki: me, Camilla, Heikki, Teemu L, Ville J.
Others on Irmeli.
We left Otasatama almost in schedule at 15:15, and arrvied to Coolaroo 16:30.
Visibility was great and the engine could be seen from surface easily, so we dropped the shot right next to engine block and anchored the boat.
For Camilla this was her first dive of the season.
Me an my daughter Camilla went to water first. There was a storng eastward surface current so we had to swim hard to the marker canister.
Dropped down slowly and circled around the engine for 30 min then back up as Camilla's tanks was at 70 bar. Took some pictures with my Olympus camera, visiblity was pretty good and there was lot of light.
Camillas dry suit had a leak on righ hand glove and entire hand got wet.

There had been some engine problems with Hinkki. On the way to Coolaroon we were able to drive at 3400 RPM 19 kts. On the way back 3300 RPM at 17 kts.

We stopped at Skiffer min Kaivopuisto to fuel up the boats and eat pizza. It was really hot at the terrace and superb weather.
