The Finnish sailing ship "Aimo"

In a snow storm in the middle of December 1898 the Finnish sailing ship "Aimo" failed in a tacking maneuver and sailed straight into the archipelago outside Nämdö and stranded on the skerries "Vitkobbarna". With the two ship's boats, the whole crew got safely to the nearby island of Rågskär. Eighteen soaking wet men doing a surprise visit in the early evening at the crofter's cottage!

The ship could not be saved. It was sold and the wood was used for building houses. Later the left-overs of the ship was used as an artillery target by the Swedish navy. At Långholmen, an island close to Runmarö (North of Nämdö), tradition says that part of a peer and part of a barn came from the Aimo ship. This sample was taken from the barn. - The "Aimo" was built in Åbo and launched in 1866. If this stock is a part from "Aimo" - which we have good reasons to presume - some 70 rings of sapwood have been cut away as the outermost ring in this "slice" grew in 1792.

Analysis

The analysis was done with a collection of 37 members, each representing a mean value curve (in .d12 or .wid format) from an area in Sweden, Norway, Denmark, Estonia and Finland. The presumed Aimo sample was selected as the reference in CDendro and the command Test Towards reference was run from the collection.

The best matching results list like this:

With the presumed Aimo sample provisionally dated to 1792 the matching of each member to that year could be analysed. With then only the best eigth members selected, I got:
