Description Oostvoornse Meer
The Oostvoornse Meer 12
The Oostvoornse Meer 12 (OVM12) is a large wooden seafaring ship, dating to the 17th century. The ship has at least two decks and a possible third (half)deck. The hull has multiple layers and the reinforcements of the ships board and deck suggest the ship was once heavily armed with canons. It is possible the OVM12 was a warship.
The diving inspection in 2014 showed the wreck was not, or barely, affected by the shipworm, Teredo navalis. It had no signs of attacks by shipworms in the past and present. This makes the OVM12 the only wreck in the Oostvoornse Meer that has not been affected by the marine borers. The one wood sample confirms this. The ropes and pieces of leather are also in very good condition.
Although the wreck is in good condition now, it is probably only a matter of time until the wreck will be affected by the shipworm. The salinity, temperature and oxygen level in the lake are perfect for shipworms, only the temperature in deeper areas is too low for the shipworm to become a threat. A change of the salinity of the water can be a solution for preventing the shipworm to affect the OVM12 and other shipwrecks in the Oostvoornse Meer.
In June 2015 the Cultural Heritage Agency of the Netherlands (RCE) will start a campaign to determine the quality of the wreck and to value the site. The possibilities to protect the wreck and the possibilities to open the site for sports divers will be researched. A detailed site plan will be made with 3D techniques.
The results of the campaign will be used to give an selection advice for the OVM12, which can be used for the protection of the wreck site.
