The S&S Week-Ender represents a pivotal moment in American yachting history, marking one of the earliest successful attempts to produce a standardized, high-quality cruising sailboat for the nascent production market. Designed by the nascent Sparkman & Stephens firm as Design No. 191 and built by the legendary George Lawley & Son, this 35-foot sloop blended the performance pedigree of a racing yacht with the manageable proportions required for family coastal cruising. Launched in 1938, the "Week-Ender" was marketed as a complete package with a fixed price and a standard equipment list—a revolutionary departure from the custom-build traditions of the pre-war era. These vessels were constructed at the Lawley yard in Neponset, Massachusetts, where the phrase "Lawley-built" ensured a standard of craftsmanship that has allowed many of the approximately 40 hulls produced to survive into the 21st century.

Sailing Performance & Handling
The Week-Ender was designed by Olin Stephens to be a "wholesome" boat, a term of art in the 1930s that implied a balance of speed, stability, and comfort without the extremes found in pure racing machines. With a displacement of approximately 14,000 pounds and a full keel with a deep forefoot, the boat exhibits the classic "sweet" handling characteristics for which Sparkman & Stephens is renowned. The hull’s narrow beam and significant overhangs provide a traditional aesthetic, but also contribute to a smooth motion in a seaway, as the waterplane area increases predictably as the boat heels.
Under sail, the Week-Ender is recognized for its exceptional tracking ability and "heavy-weather" poise. Owners often report that the boat feels significantly larger than its 35-foot length might suggest, particularly when punching through a chop. The original fractional rig, which featured a large mainsail and a smaller jib, required active reefing as the wind freshened, though many surviving examples have been modified to more modern masthead configurations or simplified sail plans. According to historical design notes from the Sparkman & Stephens Association, the design was intended to be easily handled by a couple, featuring a self-tending staysail on some variants and a cockpit layout that placed primary winches within reach of the helmsman.
Interior Comfort & Variations
The interior of the Week-Ender reflects the utilitarian elegance of the late 1930s, prioritizing structural integrity and efficient use of space over modern "open-concept" layouts. The standard configuration features a classic four-berth arrangement: a forward V-berth for two, and two settee berths in the main salon. The use of high-quality Lawley-grade mahogany joinery and white-painted bulkheads provides a bright, maritime atmosphere, though headroom is somewhat restricted by modern standards, tapering as one moves forward.
The galley is typically located aft, flanking the companionway to maximize ventilation and allow the cook to remain in contact with the crew in the cockpit. While most Week-Enders followed the standard Design 191 specification, minor variations in cabinetry and the inclusion of a dedicated nav station were sometimes seen depending on the original owner's requirements. It is important to note that the Week-Ender was a precursor to the famous S&S "Pilot" series; while the Pilot (Design 539) featured a more modern hull shape and increased beam, the Week-Ender’s interior set the template for what became the quintessential American cruiser layout for the next three decades.
Popular Mentions & Media
The Week-Ender’s cultural footprint is deeply tied to the rise of Olin Stephens as the premier naval architect of the 20th century. The boat is frequently cited in maritime histories, such as "Lines: A Celebration of the Yacht Designs of Sparkman & Stephens," as the vessel that proved standardized production could coexist with elite craftsmanship. The MIT Museum, which houses the McInnis-Lawley Collection, maintains the original architectural plans and photographs of the Week-Ender series, cementing its status as a significant artifact of American industrial design.
Known Issues & Buyer’s Checklist
Purchasing an S&S Week-Ender today is an exercise in wooden boat stewardship, as all original hulls were built using traditional carvel planking. Prospective buyers should focus on the following high-signal areas:
- Iron Floors and Ballast Bolts: Many Lawley-built boats of this era utilized iron floor timbers for strength. Over time, these can corrode, leading to "rust jacking" that puts immense pressure on the surrounding wood and fasteners. Inspecting the transition between the ballast keel and the wood deadwood is critical.
- Fastener Fatigue: The original bronze screws used to fasten the mahogany or cedar planks to the oak frames may have reached the end of their service life. A professional survey should include "pulling" several fasteners to check for de-zincification or "necking" where the screw meets the frame.
- Deck and Cabin Trunk Leaks: The Week-Ender’s deck was originally canvas-covered wood. If this has been replaced with fiberglass or if the canvas has failed, water may have migrated into the deck beams and the carlins supporting the cabin trunk.
- Rudder and Stern Post: The heavy rudder is hung on the trailing edge of the keel. Check for play in the bronze gudgeons and pintles, and inspect the wood of the stern post for signs of softening or rot near the waterline.
Community & Resources
Owners and admirers of the Week-Ender are supported by a dedicated network of classic yacht enthusiasts. The Sparkman & Stephens Association is the primary technical resource, offering a repository of design-specific information and a registry of surviving hulls. Additionally, the Lawley Heritage Day and the various "Lawley" research groups within the Massachusetts maritime community provide a wealth of historical context for those restoring these vessels to their original 1938 specifications.
The Verdict
The S&S Week-Ender is a connoisseur’s yacht, offering a direct connection to the golden age of American boatbuilding and the design genius of Olin Stephens.
Pros:
- Aesthetic Pedigree: One of the most beautiful "classic" profiles ever drafted, with Lawley’s legendary build quality.
- Sea-Kindliness: Exceptional balance and a comfortable motion in heavy weather.
- Historical Significance: Owning a Week-Ender is a form of maritime preservation, as it is a recognized milestone in yacht evolution.
Cons:
- Maintenance Requirements: As a 1930s wooden vessel, it requires significant annual upkeep and specialized knowledge.
- Limited Headroom: Taller sailors will find the interior dimensions cramped compared to modern production cruisers.
- Obsolescent Rigging: The original fractional rig requires more effort to balance than modern masthead configurations.
