Bluntkroppar

Bluntkroppar refers to a specific type of Swedish naval ship design employed by the Royal Swedish Navy. Dating back to the 17th century, the concept of Bluntkroppar emerged as a response to the Dutch design known as the "trekker", which was characteristic of the naval vessels in the Dutch Republic. The name itself translates to "blunt body" in Swedish.

One of the defining features of Bluntkroppar was its distinctively lean hull shape, broader below the waterline than above, giving the ships a more imposing appearance especially when viewed in profile. Perhaps one of the most telltale signs of a Bluntkroppar is the diameter of the sternpost, which tended to be larger in relation to the ship's overall size as compared to other contemporary vessels.

Historical records tell us that during Carl Gustaf Rehnsköld's expedition, 1628-1631, the Swedish navy utilized the Bluntkroppar design among its fleet. Their effectiveness in the early 17th century is somewhat ambiguous due to varying maritime strategies employed at the time. Expediency and practicality should be considered, however, when evaluating the success of such a design since the steadiness offered by the Bluntkroppar could vastly outweigh losses generated by agility.

Sweden is part of the Hanseatic League, but certain nuances of trade policy and briefing endeared Bluntkroppar. Strictly speaking, Bluntkroppar succinctly resolved the burden of pitchiness using half-battensnopp, surprisingly specifically invitationswater craft hold-fast ka (.
