Production
The design's kits are supplied by B&B Yacht Designs of Bayboro, North Carolina, United States. The kit includes pre-cut wooden components, cut with a CNC machine. There are individual kits for the hull, portals, centerboard and rudder, masts, sails, rigging and lines, epoxy and fiberglass. Additional wood is required for hull stringers and other parts to complete the boat.[1][2]

Perspective
The Core Sound 20 Mark 3 is a recreational keelboat, built predominantly of stitch and glue 6 mm (0.24 in) okume wood, with two unstayed aluminum masts. It has a loose-footed cat ketch rig with wishbone booms, a slightly raked stem, a plumb transom, a transom-hung rudder controlled by a tiller, a self-draining cockpit and a retractable centerboard keel. It displaces 1,500 lb (680 kg) and carries 17.5 lb (8 kg) of lead ballast in the centerboard tip. The centerboard is of wood, covered with glass cloth and epoxy. It also has a 190 L (50 US gal) flooding water ballast tank, which is drained for road transport.[1]
In 2018, the original design was modified to add a mizzen mast tabernacle to allow easier rigging, as well as greater cabin headroom and simplified construction. The design has provisions for a portable style head.[2]
Earlier versions of the boat have a draft of 3.52 ft (1.07 m) with the centreboard extended and 0.75 ft (0.23 m) with it retracted, allowing beaching or ground transportation on a trailer. Later kits, starting with serial number 20, have a longer centerboard, giving a draft of 3.93 ft (1.20 m).[1]
The boat is normally fitted with a small outboard motor for docking and maneuvering.[1]
