Preliminary interpretation

Dendrochronological analysis of the wreck suggests that the wood comes from the northern coast of the Baltic Sea with a preliminary dating to 1780. This suggests a possible connection to the Swedish Navy and Gustav III's war (1788–1790), although this interpretation is yet to be confirmed.

The initial interpretation of the wreck suggests it may have been deliberately sunk. This is indicated by large stones found inside the hull of the wreck that seem to have been used to sink the ship rather than as ballast. This interpretation is supported by the location and orientation of the wreck in a sheltered area and oriented towards the island, indicating intentional placement. It is possible the ship was sunk as part of an unfinished construction project. In this case, it could have served as a breakwater, creating a sheltered area between the shore and the reef. Another possible purpose for sinking might have been related to the plans of the former bridge of Susisaari.

Subsequent research focused on determining when the ship was repurposed as an underwater structure. If the Archipelago Fleet was involved in its repurposing, auction documents for rigging could provide valuable information. With the dating results, archival searches were narrowed to the period after the 1780’s, focusing on the records of the Helsinki Auction Chamber. These searches were conducted by maritime history students from the University of Helsinki under the guidance of maritime historian Mikko Huhtamies. Unfortunately, no additional information about the wreck was found from the archive.

Another lead was found on a map identifying a vessel named Victoria near the wreck's location on the southern shore of Iso Mustasaari, near the current authority dock. Associate Professor Marcus Hjulhammar discovered a 1795 newspaper advertisement of the auction of a barge named Victoria. This barge was built in Pori (Björneborg), that is in the area indicated by the dendrochronological results. Perhaps the ship was not sold and was sunk instead. Should the wreck at Western Mustasaari be Victoria, it would have been less than 15 years old at the time of the auction. This is relatively young for a barge type known for its longevity. Additionally, a ship named Victoria is not found in the Archipelago Fleet's list of vessels.

Yet another possible clue to the wreck's history comes from reports suggesting that the Swedish fleet, that surrendered in 1808, was stationed in Satamalahti during the Russian period. However, this information is unconfirmed and comes from a single source. Were it accurate, the wreck could be one of the 110 ships handed over to the Russians. In terms of size, it could be a Turunmaa-class frigate.
