Ljungström sailboat

Ljungström sailboats were created by the Swedish engineer Fredrik Ljungström, who was interested in sailing since childhood. A "Ljungström sailboat" typically has a Circular arc hull and a Ljungström rig. A Ljungström rig mast has no mast stays. The mast rotates on two ball bearings often flying double mainsails, with no foresails. In their time the Ljungström sailboats were a minor revolution as they were fast, safe and easy to sail as well as relatively easy and affordable to produce.

The models were named The Wing and the number (Swedish Vingen 1, Vingen 2 etc.) chronologically. A few models were built in series, such as Vingen 11A and the Twin Wing which was specifically produced for the US market. The design was not appreciated by the fairly conservative yacht clubs at the time, so development was done with scarce means.

Approximately sixty boats (of different sizes) were produced. Approximately eighteen are known to still exist; a dozen of those are sailing, and the rest are undergoing renovation or waiting for renovation.
