The Challenger 7.4, also widely recognized as the Challenger 24 or Challenger 7.5, is a compact monohull sailboat that emerged from the Canadian builder Challenger Yachts Ltd.. Designed by the notable British maritime architect Alex McGruer, this vessel was conceived to be a practical and accessible sailboat, offering a balance of usability and performance for its size 1, 3, Builder Article. With a length overall of just over 24 feet, the Challenger 7.4 quickly established itself as a popular option for coastal cruising and day sailing enthusiasts, produced primarily between 1974 and 1980.

History and Design
The Challenger 7.4's story is intertwined with the ambitions of Challenger Yachts Ltd., a company founded by Kalman Bekesi in Canada during the 1960s. The builder article highlights the company's reputation for producing well-designed sailboats, a testament to its collaboration with skilled naval architects like Alex McGruer. McGruer, who also designed other models for Challenger Yachts, aimed to create functional and enjoyable sailing experiences in his designs, 12, 13].
The Challenger 7.4, constructed using fiberglass for both its hull and deck, represented Challenger Yachts Ltd.'s commitment to modern and durable production methods of the era. While the Challenger 24 first set sail in 1973, the 7.4 designation saw its primary production run from 1974 to 1980, with approximately 800 units built. While most units were eventually powered by outboard motors, the original design envisioned a Renault diesel engine.
Sailing Performance and Handling
As a masthead sloop with a fin keel and spade rudder, the Challenger 7.4 was designed to offer a solid and enjoyable sailing experience. Its design characteristics suggest a boat that prioritizes stability and stiffness on the water. While described as a "light sailboat," it is also noted for being "very stable / stiff". This combination, coupled with its relatively high ballast-to-displacement ratio, suggests a vessel capable of standing up to a decent breeze, providing a comfortable and secure motion. With a length overall of 24.33 feet and a waterline length of 22.17 feet, it offers a respectable hull speed of 6.31 knots.
The Challenger 7.4 is generally considered to be somewhat underpowered, which implies it might not be the fastest boat in light air conditions. However, its robust stability would likely make it a forgiving boat for new sailors and a comfortable platform for coastal cruising in moderate winds. The common use of an outboard motor for auxiliary power further underscores its design as an accessible and manageable vessel for recreational sailing.
Accommodations and Layout
Despite its compact size, the interior of the Challenger 7.4 was designed to maximize functionality for its intended purpose as a small cruiser. The typical layout includes a V-berth forward, providing sleeping accommodations in the bow. A semi-private head is usually located between the V-berth and the main salon. The salon area often features a small dinette that can convert into an additional berth, along with a galley counter, offering basic amenities for meal preparation. A quarter berth often provides another sleeping area aft, making the Challenger 7.4 capable of accommodating a small crew or family for overnight trips. The interior finish, typical of fiberglass boats of its era, would likely have focused on practicality and durability, with common use of fiberglass liners and wood trim accents.
