Slipper 42 Information, Review, Specs

History and Design

The genesis of the Slipper 42 lies in the transformation of an existing design. Tyler Boat Works acquired the molds for the Rancher 41, originally a racing hull designed by Alan Gurney. Robin Chadworth-Musters then extensively modified this foundation, significantly raising the topsides and replacing the original bolt-on keel and spade rudder with internal ballast and a more robust skeg rudder. This crucial re-engineering successfully converted the performance-oriented Rancher 41 into the Slipper 42, a yacht specifically designed for comfortable cruising rather than outright racing. Musters was also responsible for the new deck and interior layout, tailoring the vessel to its new purpose.

Tyler Boat Company Ltd., the builder of the Slipper 42, was a pivotal player in the fiberglass revolution of yacht construction, known for its high-quality GRP (Glass Reinforced Plastic) hulls and decks. The company, which commenced operations sometime after 1946, became a prolific supplier of fiberglass components to other builders worldwide, in addition to producing its own line of yachts. Tyler's commitment to robust construction ensured that their hulls, including that of the Slipper 42, were built to last. The production of the Slipper 42 began in 1978, coinciding with the period just before Tyler Boat Co. Ltd. ceased its boatbuilding operations after 1978.

Sailing Performance and Handling

The Slipper 42, with its ketch rig, fin keel, and skeg-hung rudder, offers a sailing experience tailored for comfort and stability, particularly suited for extended passages. Her design ratios confirm her cruiser credentials. With a Sail Area to Displacement ratio of approximately 15.8, she is moderately powered, suggesting a steady performance in various wind conditions without being overly sensitive in lighter airs. The Ballast to Displacement ratio of around 43.4% indicates a stiff and stable hull, capable of standing up well to a breeze and providing a comfortable motion in a seaway. Furthermore, a Displacement to Length ratio of approximately 264 places her firmly in the category of a moderate-to-heavy displacement cruiser, signifying a robust build and sea-kindly characteristics.

Anecdotal evidence supports these figures, describing the Slipper 42 as a sailboat with "moderate displacement" that is "slightly underpowered" yet "very stable/stiff" and possesses "good righting capability". The ketch rig is often praised for its versatility, allowing for easier sail handling and a balanced sail plan, particularly beneficial for comfortable downwind sailing or on broad reaches. Her robust construction and stable nature make her a reliable choice for offshore cruising.

Accommodations and Layout

The interior of the Slipper 42 was designed by Robin Chadworth-Musters, focusing on creating a practical and comfortable cruising environment. As a center-cockpit ketch, she typically offers a well-defined separation between the main salon and an aft cabin, a desirable feature for privacy on longer trips. While specific headroom figures are not readily available in the detailed specifications, the raised topsides, part of the conversion from the Rancher 41, imply a more generous interior volume than her predecessor.

Typical layouts often include multiple berths, with some configurations accommodating up to six individuals. Owners can expect a functional galley, a dedicated head, and a comfortable salon area. The substantial fresh water capacity of 115 gallons and fuel capacity of 114 gallons further underscore her design as a serious cruising vessel, capable of extended self-sufficiency. Reviews and listings suggest a focus on practical amenities, often including a hot water system, vital for comfortable living aboard. While specific details on interior finish materials would vary with individual fit-outs, the underlying Tyler hull provided a solid foundation for a durable and well-appointed living space.
