[1][3][5][6][7] The Stuart Knockabout is a recreational keelboat, initially built of wood and later adapted for fiberglass over an Airex foam core construction by Bill Harding of Edey & Duff.
The hull has a spooned, raked stem; a raised counter, angled transom; a keel-mounted rudder controlled by a tiller and a fixed modified long keel, with a cutaway forefoot and a retractable, solid PVC centerboard, with raising gear with a 2:1 mechanical advantage.
Factory options include teak seats, a boat trailer for road transport, a spinnaker, genoa, a second oar, a side-mounted outboard motor bracket and a swimming ladder.
"[3] Rob Peake wrote a review for Classic Boat magazine, in which he said, "the 28ft Knockabout carries 265 square foot of sail and is a common step-up for the Herreshoff 12½ sailor, also for those downsizing from a yacht.
You get plenty of space, enough for a family, an easy-to-handle rig and judging by her performance in the perfect evening breeze we’re blessed with, a stable hull (a light, foam-cored fibreglass sandwich with 400 pounds [2400 lbs] of keel ballast).
