Sunday trip to Porkkala wreckpark.
Dive 1/3.
The park is north of the island of Träskö, just 10 min boat ride from Porkala Marin.
There are 3 shallow wrecks marked with buoys and guidelines, and mooring buoys for a boat.

I volunteered as the captain for this trip. We were 6 divers in total: me, Keni, Alex, Eero, Marcus and Markus.

We started from the Kuplakammio at 9 am. Then at Porkala Marin harbour at 10 am.
Loaded the Hinkki boat and then headed to the park just 10 min boat ride away.
It was quite cold and cloudy for early August.
Moored to the buoy at Alko wreck, which we dived first.
I dived with Alex as the last pair. Alex had a single 12L tank, I had twin-10L.

I took pictures with Olympus TG-5 in PT-058, with AOI UWL-04 lens and 2x Nanight 4KLm video lights.

The Alko wreck is tiny, about 10-15 meters long, so not that much to see. Also very badly borken at shallow water. We circled it 3 times, then got bored and came up.
Visibility was like 2 meters but there was still light at 8 meters.
Alex did not have a light but managed without.

After this dive we drove back to harbour to have some pizza as lunch.

===================
Text from the wreckpark site:

The Alko wreck is well suited dive site for entry level scuba divers or even snorkelers, as the shallowest parts of the stern rise up to 4-5 meters depth. The bow lies in about 9-10 meters on a rocky slope of the reef. The wreck can also be dived from the island shore and it’s well protected from most winds.

The faith and origins of this 19th century coastal freighter are well known. It was wrecked in May 1880, on its way from its home port Parainen to Helsinki. It was fully loaded with lime stone cargo, which is still abundant in the wreck. The name of the captain was Johan Karlsson. Rumors of an insurance fraud were heard long after, as the ship wrecked so close to the island, that it should have been observed, no matter the weather.

The wreck remains about 15 meters long from the bow and in fairly good shape, given the shallow depth it lies in. Most of the deck planking is gone, but half a dozen beams remain, keeping the both boards intact.
