Escape Room: Mission Sea Eagle

Special agents, welcome to this briefing. Your mission is urgent.  According to our sources, a huge oil tanker is coded to run straight into Helsinki's Marketplace, destroying not only the city center but also the sensitive Finnish Bay.

We know that the terrorist has a sailing boat somewhere close to Suomenlinna fortress, from which he can activate his operation. He's just waiting for his boss, Romero Litski, who's due to arrive any time now.  You need to to find the boat before Litski gets there, and send us its identification code, so that we can move in and stop the threat. Will your team be able to find the clues that Litski has hidden in Suomenlinna ? You have only a couple of hours to complete the search.
