Shtandart

real pirates? I investigated (it took me quite a while after all this years just by having a picture) and found this:

The frigate Shtandart (Russian: Штандартъ) is modern replica of the first ship of Russia's Baltic fleet, was launched in 1703 at the Olonetsky shipyard near Olonets by the decree of Tsar Peter I and orders issued by commander Aleksandr Menshikov. The name Shtandart was also given to the royal yachts of the tsars until the Russian Revolution in 1917. Tsar Nicholas II's royal yacht was last of this series.
