Message in a bottle

We are in 1907. Exactly 100 years ago, the warship H.M.S. Blenheim started its journey to the Cape of Good Hope – but it never arrived. It was last seen on 18th February 1807. It was believed to have been lost for 100 years. Until today! After we had received a message in a bottle we were able to localize the ship. According to our knowledge there is a huge treasure chest inside the ship! We now need a team which is clever enough to bring the treasure back ashore. Are you able to find the treasure? Are you the best team?
