Part of the "Helsingin Helpot" weekend of dive club Kupla
https://kupla.org/int/events/601/helsingin-helpot-orion/
Orginal plan was for 6 divers, but Pekka joined us at the last moment, so 7 in total.
Me, Camilla, Pekka, Heikki, Ella, Alpi, Anna.
Weather was again perfect, sunnu and warm, light wind, small waves.

We left at 9:00 form Otasatama with Hinkki boat and arrvied to Orion 10:00. Tried to find the big boiler of the wreck using sonar, but the coordinates were not good and nothing showed up on sonar screen. Finally dropped the marker shot to coordinate location and anchored the boat between the marker and the rocks at NE, depth below boat 12 meters.

Me and my daughter Camilla went as 2nd pair, right after Alpi and Ella. We descended slowly near the marker line to the bottom at 14 m. But the bottom was empty, so started swimming towards 60 degrees up the hill, and found the main part of Orion wreck at 12 m depth after 8 min. Then found the boiler towards E at 13 m. The boiler itself is 2...3 meters tall, so top of is at 11 m. There was a shar thermocline at 12 meters, below it 7 degrees, above it 11 to 14 degrees, feeling significantly warmer.
After the boiler we continued upwards the hill and found pieces of wreckage everywhere, mostly smaller pieces of metal. Then spent lot of time dibving at 5...6 meter depth along the hill and found a big piece of wreck near the rocks going to surface. Apparently the steamship Orion has hit the rocks here, and then it sank on the hill. Ice sheets in winter have ground the wreckage into pieces over the course of many decades.
We had agreed 45 min dive time, so when that was approachin I shot an SMB up, then we surfaced and swam back to boat. Some other divers had near encounters with seals, but we did not see any under water.
Had my Olympus camera with and took some pictures.
Visibility was pretty good and there was lot of light.
Camilla's dry suit leak on right hand continued.

At 12:15 we were ready to drive back to harbour and arrived 13:30, so very well in schedule. On the way back Hinkki engine ran at max RPM 3200 yielding 17 kts.
