I could not find much on the “Jolle Roskilde Fjord” the design is made after a photo taken in the 1920’s which shows the young Christan Nielsen with a wooden boat under sail and steering with an oar. By the photo is given that it is a “Lynaes jolle” which were used a lot in the Roskilde Fjord at that time.
Clinker built with dim. of about 3.04 x 1.31m, not a drawing was made and the boat was built after the builders measurements. “jolle” is the Scandinavian term for “dinghy”.
Mostly used for inshore and lake fishing. Rowed or skulled and can set a mast which carried a spritsail.
