In 1887 on a trip from Copenhagen to Danzig the Arcturus collied with the SS Savona and sank off Fasterbo. No lives were lost as the Savona picked everyone up.
The Laura was built in 1882 and was bought by a Captain Peter Mærsk Møller, in 1886 for the Copenhagen to Faroe run (stopping at Edinburgh on the way). I did a double take at that name for Mærsk Møller, is one of the biggest shipping companies in the world and it turns out that the purchase of the Laura was the start of Captain Peter Mærsk Møller shipping career, his first steam ship. (The middle name of Mærsk is from his mother's family name and in Danish means marshland). The Laura was wrecked off Iceland in 1910.
