The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season.
The Northeast 38 Yawl Mk I is equipped with a yawl rig. A yawl rig is generally considered easier to handle, because the sails are smaller, and because it can sail on most points to the wind with one sail completely taken down for repair or while reefing. The sail configuration of a yawl allows for better comfort and stability when sailing downwind or on a broad reach.
