A 16′ (4.88 m) harbor workboat

by Laurie McGowan


From WoodenBoat magazine No. 259, November/December 2017: BOXER carries a box-keel, somewhat like William Atkin’s Rescue Minor, below its scow-shaped hull. This distributes the volume better and provides a storage space for the motor—either diesel- or electric-powered.

The wheelhouse has standing headroom, and the below-deck space has a small galley, a work bench doubling as a berth, and a head forward. The seat near the helm can also serve as a work bench and has a tool locker inside.

BOXER has a fairly efficient powering curve, and the 100% torque at all rpms of the electric motor makes the boat perfect for moving heavy things around at slow speeds.
