The Block Island 40 is a venerable sailboat, renowned for its robust construction, comfortable motion, and classic lines that harken back to a golden era of yachting. Conceived by the celebrated naval architect William H. Tripp, Jr., and first launched in 1957, this fiberglass yawl was designed as an honest cruising boat, well-suited for coastal voyages and offshore passages for a couple or small family. Its enduring reputation stems from its solid build and the capable sailing characteristics inherent in Tripp's designs. Production of the Block Island 40 involved several builders, initially by the Beetle Boat Company, and later by Metalmast Marine, a company primarily known for its world-class aluminum spars.

History and Design

The Block Island 40 traces its origins to 1957, making it one of the earliest production fiberglass boats of its size. Designed by William H. Tripp, Jr., it was based on his earlier "Vitesse 40" concept, developed in the Netherlands. Tripp's design philosophy for the Block Island 40 aimed to create a capable offshore cruiser, embodying a blend of traditional aesthetics with innovative fiberglass construction.

Initial production of the Block Island 40 was undertaken by the Beetle Boat Company, which built the first 26 hulls. Subsequently, the molds were acquired by Metalmast Marine of Putnam, Connecticut. While Metalmast Marine was primarily a leading manufacturer of aluminum masts and rigging components, their foray into building complete sailboats like the Block Island 40 showcased a broader expansion of their capabilities. The Metalmast-built version of the Block Island 40, sometimes referred to as the Block Island 40-2, featured notable modifications, including a separate spade rudder and a reverse transom, and continued production until around 1978. The design was even re-introduced on a limited basis in the early 1980s by Migrator Yachts, with a hull similar to the original but a redesigned deck and coach roof. The Block Island 40 proved its mettle early on, with a number of yachtsmen successfully campaigning them in events such as the Newport-Bermuda Race.

Sailing Performance and Handling

The Block Island 40, with its length overall of 40 feet and a waterline length of 27.5 feet, boasts a significant displacement of 21,000 pounds, classifying it as a heavy displacement cruiser. This substantial weight, reflected in its high displacement-to-length ratio, typically translates to a comfortable and stable motion in a seaway, making it forgiving in rough conditions and capable of carrying significant stores for extended cruising.

Her sail area to displacement ratio of approximately 13.66 suggests a conservative sail plan relative to her displacement. While this may mean she requires more wind to truly get up to speed in light air, it also indicates a powerful and easily managed yacht in stronger breezes, less prone to being overpowered. The Block Island 40's ballast-to-displacement ratio of around 0.238 is relatively low for a fixed-keel vessel, but this is characteristic of her centerboard design. The centerboard, with a minimum draft of 3.92 feet and a maximum draft of 8.42 feet when fully extended, provides excellent lateral resistance for upwind performance while allowing access to shallower anchorages. Owners generally describe the Block Island 40 as an honest and predictable boat with few vices, known for its balanced helm and steady course-keeping, particularly when properly trimmed. Her theoretical hull speed is calculated at 7.03 knots.

Accommodations and Layout

The interior of the Block Island 40, while designed for cruising, is noted for its more traditional proportions, which some describe as having adequate but not expansive volume, particularly by modern standards. Despite this, the layout typically offers a functional and comfortable living space for a cruising couple or small family.

Common interior arrangements usually feature a V-berth forward, followed by a head compartment. The main salon traditionally includes opposing settees, often with a folding table, creating a comfortable dining and lounging area. A galley, typically positioned to port or starboard, would provide basic amenities for meal preparation, and quarter berths are often found aft, providing additional sleeping capacity. While the specific maximum headroom is not consistently documented, early designs aimed for over six feet of standing headroom throughout much of the cabin. Owners praise the classic wood trim and sturdy construction of the interior, contributing to a warm and traditional feel. Storage is generally considered ample for a boat of her size and era, with lockers and shelves throughout the cabin.

Owner's Perspectives

Owners of the Block Island 40 consistently praise its solid construction and seaworthy capabilities, often highlighting its ability to handle challenging conditions with a comfortable motion. Many appreciate the classic aesthetic and the quality of craftsmanship that went into these early fiberglass yachts. The centerboard configuration is frequently cited as a significant advantage, offering both enhanced sailing performance upwind and the ability to explore shallower waters.

However, some owners note that the traditional, heavy displacement design means she isn't a fast boat, particularly in light winds. As with any vessel of her vintage, common maintenance items might include addressing original deck fittings that could develop leaks over time, requiring re-bedding. Despite these potential considerations, the Block Island 40 maintains a loyal following among those who value a robust, comfortable, and classically styled cruising sailboat.
