context_page_description: A pojama or pojema was a type of warship built for the Swedish archipelago fleet in the late 18th and early 19th centuries. It was developed for warfare in the Archipelago Sea and along the coasts of Svealand and Finland against the Russian navy. The pojama was designed by the prolific naval architect Fredrik Henrik af Chapman for use in an area of mostly shallow waters and groups of islands and islets that extend from Stockholm all the way to the Gulf of Finland.
  The pojama was intended to complement and partially to replace the existing galleys of the Swedish inshore squadrons, but were designed as hybrid sailing vessels that could also be rowed.
context_section_description: The first pojama was built in 1764 (the same year as the larger version turumas and the earliest hemmema). It was a low-hulled vessel with two masts, a main and a mizzen, rigged like a bomb ketch with two square sails, a lug sail, and three staysails supported between the mainmast and the bowsprit. The first pojama was 23.8 m (78 ft) long, 5.5 m (18 ft) wide, with a draft of 1.8 m (6 ft). The three later pojamas built for the Swedish navy varied in size from 20 m (65.5 ft) up to 27.6 m (90.5 ft). Its main armament was two heavy guns in the bow and stern (ranging from 12-pounders up to 24-pounders). These could also be dragged towards the center of the vessel and aimed sideways, though with considerable effort. It also had up to 10 swivel guns along the railings for close-range defense. For maneuverability, it carried 14 pairs of oars which operated through oarpoarts attached to a rectangular outrigger which improved the leverage for the oarsmen.
