Comments

First dive of season in Finland with KUPLA club's Irmeli boat.
Pasi, Mikko V, Esa and me, just 4 of us.
6 had enrolled, but 2 cancelled.
Met at Kuplakammio at 9ish and got to the Otasatama harbousr around 10.
Irmeli had not been in water this season yet, so we had to prepare the boat.
With Pasi's car we towed Irmeli to water, as there was no longer ice in the bay of Laajalahti. Plan was to go to Coolaroo wreck.
Ice had just melteted a few days ago. It was really cold. Air about 6 deg-C, slight rain and wind.
Started driving the boat towards Coolaroo, but waves were too hard to get that far out, so we decided to stay at the island of Truttkobben. Moored Irmeli to North side attaching to the rocks and dropped anchor, so we could all dive at the same time.
Me and Esa went first as we both ahd OC, Mikko and Pasi had CCRs.
Water was 2 degrees at all depths, and I soon felt really cold, Esa tolde later he was not cold at all. WE tried to find a small wreck that was at 18 meters, found some pieces of wood. I had to start heading back after 20 min as I was so cold.
Pasi and Mikko returend soon after us, and then we drove back at shore. Could not refuel the boat as no stations were open yet.
Had also my small Olympus TG-5 with me and took some pictures.
