21 ft Koster Boat 'Sjogin' Design #176

The plans for this small double ender were drawn for a group of enthusiasts organised over the internet by Rod Brink of Fargo, Texas.  The hull lines are those of the Norwegian Koster boat 'Sjogin' owned by Russ Manheimer of Manasquan, New Jersey.  It was from Russ's measurements that these plans were made, modified somewhat and drawn up with a choice of three construction methods and four rigs.  It is a sweet boat with weekend accommodation that will appeal to the traditionalist regardless of the construction method chosen.
