What non-profit organization did one of the builders of the UC1 Freya co-found?
UC1 Freya Freya or "UC1 Freya" (in Danish: "Freja") was the first private Danish submarine, and thus first amateur electric sub in Denmark. It was built by Peter Madsen and Claus Nørregaard in 2001-2002, as a demonstrator to try submarine technology. Having made over 500 dives, it was decommissioned, as it was not designed for a long service life. It was decommissioned in 2006 after UC2 Kraka had been worked up. The submarine was then docked and allowed to decay. Final decontamination was done, and it was towed out to sea by UC3 Nautilus, in August 2008, and sunk as an artificial reef near Copenhagen.
