In 1993, archeologists recovered most of a buried wooden boat near Gislinge, on the island of Sjælland in Denmark. The 7.7-meter boat was dated to the year 1130 AD.

The Viking Ship Museum in Roskilde, Denmark, reconstructed the Gislinge Boat. In 2015, the Museum released the working drawings to the public, launching the Gislinge Boat Open Source Project.

In 2020, Chesapeake Light Craft will build a computer-cut "stitch-and-glue" interpretation of the Gislinge Boat. By creating a pre-cut marine plywood kit, we hope to make construction of replicas of this ancient Scandinavian boat accessible to amateur builders and organizations.

In January 2020 we built a 33% scale model of the Gislinge Boat to test the assembly sequence.

As of September 2020, there have been some epidemic-related delays, but we have proceeded to full-sized mock-ups. We hope to build hull #1 in November, 2020.

CLC designer Jay Hockenberry was responsible for the CAD/CAM engineering.
