The Lapworth Endeavor 26 is a distinctive sailboat, conceived by the notable American naval architect C. William Lapworth and built by the respected West Coast manufacturer W.D. Schock. Produced for a short but impactful period between 1963 and 1967, this 25.75-foot fractional sloop was designed with a dual purpose in mind: to excel as both a spirited racer and a comfortable day sailer. With its sleek lines and focus on performance, the Endeavor 26 carved out a reputation as a safe, comfortable, and robust vessel for its size.

The creation of the Endeavor 26 traces back to the early 1960s, a period when fiberglass was rapidly revolutionizing boat building. Designed by C. William Lapworth, a prolific naval architect known for his innovative designs that leveraged the durability and replicability of fiberglass, the Endeavor 26 aimed to offer a speedy hull in a compact package. W.D. Schock, founded by William "Bill" D. Schock, brought this design to life. The company, which established itself as a leading builder of quality fiberglass yachts on the U.S. West Coast, was known for its commitment to practical design, robust construction, and performance-oriented vessels, a philosophy evident in the Endeavor 26. A total of 56 units of the Lapworth Endeavor 26 were built during its production run. There is no information to suggest significant variations or marks (e.g., MkI, MkII) during its production.

Sailing Performance and Handling

Despite its relatively compact length overall of just under 26 feet and a waterline length of 18 feet, the Endeavor 26 boasts a design that suggests lively performance. With a calculated Sail Area to Displacement Ratio (SA/Disp) of approximately 20.04, the boat is indicative of good light-air performance, meaning it should be responsive even in lighter breezes. Its Ballast to Displacement Ratio (Bal/Disp) of 0.50 is notably high, suggesting a very stiff and stable boat that can stand up well to wind and provide a secure feel on the water. The Displacement to Length Ratio (Disp/L), at around 244.9, places it in a moderate to light displacement category for its length, implying a good balance between speed and cruising comfort. The Endeavor 26 is often described as having a "needle" type hull design, hinting at its efficient and slender form. Owners and enthusiasts frequently commend the Endeavor 26 for its ease of sailing, even with minimal crew, and describe it as a safe, comfortable, and strong performer in various conditions.

Accommodations and Layout

Given its design as a racer and day sailer from the 1960s, the Lapworth Endeavor 26 features an interior layout typical of boats of its size and era, generally prioritizing open space and functionality over extensive private cabins. Publicly available detailed interior layouts or photographs specifically for the W.D. Schock-built Lapworth Endeavor 26 are scarce. The design likely includes basic accommodations suitable for weekend cruising or overnight stays, such as a V-berth forward, and a main salon area that may convert into additional sleeping berths. Headroom might be limited, as is common for vessels of this length and vintage. The focus would have been on practical use of space, possibly with a simple galley area and a marine head, offering essential amenities for short trips.
