sifferskivas

Sifferskivas is a term of uncertain origin, believed by some etymologists to derive from Old Norse words relating to "ship" and "speed" or "swiftness." Historically, it has been used to refer to a type of small, fast sailing vessel common in certain coastal regions during the medieval period. These vessels were typically characterized by their narrow beam, shallow draft, and a single mast supporting a gaff-rigged sail, although variations existed depending on local shipbuilding traditions and intended use.

The primary function of sifferskivas was often for quick transport of goods or personnel, and in some contexts, for reconnaissance or swift raiding. Their agility and ability to navigate shallow waters made them advantageous for coastal operations and for reaching harbors inaccessible to larger ships. Evidence for their existence comes from fragmented historical accounts, shipwrecks, and artistic depictions in illuminated manuscripts and carvings from the era. The exact dimensions and construction details are not always clear, leading to ongoing scholarly debate and interpretation. The term itself appears infrequently in surviving documents, contributing to its enigmatic nature. It is unlikely that sifferskivas represented a single standardized design, but rather a functional category of swift, small sailing craft adapted to specific maritime environments.
