Challenger 23 / 24 / 7.4 /7.5

Description

The Challenger 23, also known as the Challenger 24, is a classic fiberglass trailerable sailboat designed by renowned naval architect Alex McGruer and produced by Grampian Marine of Canada from 1973 to 1978, with approximately 200 units built before the company shifted focus; featuring a sleek fin keel with spade rudder hull type, it measures 24 feet in overall length (LOA), 23 feet on the waterline (LWL), and boasts a generous beam of 7.5 feet providing ample interior stability for coastal cruising while displacing around 4,000 pounds with 1,600 pounds of lead ballast for solid righting moments. Its masthead sloop rig supports a sail area of about 230 square feet, delivering a balanced sail area-to-displacement ratio of around 18 for respectable performance in moderate winds, complemented by a draft of 3.4 feet for versatile shallow-water access and a small outboard motor well for auxiliary power. The layout offers a surprisingly roomy cabin for its size, sleeping up to four with a V-berth forward, convertible dinette, and optional galley/head, though the cockpit is modestly proportioned at 5.5 feet;
