The Lehman 12 stands as a significant vessel in sailing history, recognized as one of the earliest fiberglass production sailboats in the United States. This 12-foot, cat-rigged sailing dinghy was conceived by the notable marine architect Barney Lehman, making its debut in 1953. Designed primarily as a one-design racing dinghy, the Lehman 12 gained a reputation as an exceptionally responsive and easily handled boat, capable of planing. While initially built by Barney Lehman's own company, PlastiGlass, production of the popular dinghy transitioned to W.D. Schock in the late 1950s, further cementing its place in the burgeoning fiberglass boat market.

History and Design

The genesis of the Lehman 12 dates back to 1953, when Barney Lehman introduced this innovative design. His company, PlastiGlass, was the original builder, pioneering the use of fiberglass in production sailboats. This material choice was revolutionary at a time when wooden boat building was still dominant. The design philosophy behind the Lehman 12 emphasized simplicity and performance, aiming for a responsive two-man planing dinghy with an uncomplicated cat-rig and a deep rudder. The designer opted for a "slightly more speedy hull design" to enhance its performance.

In the late 1950s, the manufacturing rights for the Lehman 12 were acquired by W.D. Schock, a company officially founded by William "Bill" D. Schock in 1958. W.D. Schock quickly became a specialist in fiberglass sailboat production, contributing significantly to the widespread adoption of this durable and low-maintenance material. The acquisition of the Lehman 12 design underscored W.D. Schock's commitment to crafting accessible yet competitive sailing vessels from fiberglass, laying a foundation for their future success with other iconic models.

Sailing Performance and Handling

The Lehman 12 is renowned for its lively sailing characteristics and responsive nature. Despite its modest size, it is described as an "exceptionally responsive two-man planing dinghy" that can "quietly glide through the water with only a whisper of wind." Its cat-rig configuration, combined with a daggerboard and deep rudder, contributes to its agility and ease of handling. The boat is particularly sensitive to crew weight, trim, and balance, allowing skilled sailors to significantly influence its performance. These attributes have made the Lehman 12 a consistent presence in one-design racing circles, especially in Southern California, where competitive fleets have been active since the boat's inception.

Accommodations and Layout

As a dedicated racing and daysailing dinghy, the Lehman 12 features an open cockpit layout, typical of boats of its size and purpose. There are no enclosed accommodations or interior living spaces on board. Its design prioritizes maximizing cockpit space for crew movement and sail handling, consistent with its role as a performance-oriented dinghy.

Owner's Perspectives

The Lehman 12 has fostered a dedicated community of owners, particularly in Southern California, where it has maintained a strong presence in one-design racing since its introduction in 1953. Owners consistently praise its straightforward design and the responsive, exhilarating sailing experience it offers. The enduring popularity of the Lehman 12 is supported by active class associations and enthusiastic owner communities, which are crucial in preserving its legacy and ensuring its continued presence on the race course. These communities often engage in competitive regattas, with races like the Lehman 12 championship run continuing to draw participants. Owners frequently discuss tuning guides and racing strategies, highlighting the boat's continued relevance as a competitive dinghy.
