Background:

This design was developed for buoy and waterway maintenance operations in the lakes of Maine. The design mission was to replace the department's 36 year-old fiberglass vessel with a boat of similar dimensions, albeit relatively small for shouldering the maintenance burden of Maine's 1,000+ freshwater buoys. The preference for small size was dictated to facilitate trailering and launching at remote and primitive ramps. Despite its relatively small size, the boat routinely carries a cargo of 2,500# consisting of buoys, anchors and chain. The buoys and gear are worked via a davit at the side hull cutout. A bow thruster is used to help keep the boat on station.

The first of these designs was built by Lyman Morse Fabrication in Thomaston, Maine.
