näyttölaitetta

Näyttölaitetta, also known as an aviso ship or a dispatch vessel, was a type of warship used by the Finnish Navy from the 16th to the 19th centuries. The term "näyttölaitetta" is Finnish, meaning "display vessel" or "notification ship."

The näyttölaitetta was designed for auxiliary purposes, serving as a messenger and dispatch vessel for the commander-in-chief of the Finnish Navy. Its primary role was to carry orders, messages, and dispatches between ships and shore-based command centers during times of war or conflict. The concept of näyttölaitetta is comparable to that of a flag ship or a corvette in other navies.

A typical näyttölaitetta would be a small sailing vessel, often a cutter or a schooner, which was relatively fast and maneuverable. Its crew was usually small, consisting of a few officers, sailors, and perhaps a few gunners. The näyttölaitetta's armament was light, typically consisting of a few cannon or swivel guns.

Throughout history, the näyttölaitetta played an important role in support of operations conducted by the Finnish Navy in the Baltic Sea region. Although it is no longer in use as a distinct type of warship, its legacy can be seen in the maritime communication and signaling practices that continue to this day.
