History and Design
The Ericson 31 Independence began its production run in 1977 and continued until 1981, during a period when Ericson Yachts was known for its commitment to durable hulls and superior quality fiberglass construction. Founded by Handy and Jenkins, former employees of Columbia Yachts, Ericson Yachts emerged in the mid-1960s with a clear focus on leveraging fiberglass as a primary boatbuilding material. The company quickly established a reputation for solid construction and thoughtful designs, largely due to its enduring collaboration with Bruce King, who designed most of the Ericson line.
Originally designated as the Ericson 31C, the model was also marketed as the Cape Bay 31 and the Liberty 31 by Squadron Yachts (USA). While the foundational design remained consistent, a notable variation included a cutter version, often featuring a bowsprit, which enhanced its offshore capabilities and sail-carrying capacity. Bruce King's designs for Ericson were characterized by balanced sailing characteristics, comfortable interiors, and pleasing lines, blending practical functionality with a timeless aesthetic, a philosophy evident in the 31 Independence.
Sailing Performance and Handling
The Ericson 31 Independence, with a length overall of just under 31 feet and a waterline length of 23.92 feet, is designed for a stable and comfortable sailing experience rather than outright racing speed. Her displacement of 11,400 pounds combined with a relatively short waterline indicates a heavier, more traditional cruising vessel, categorized by a high displacement-to-length ratio of approximately 372.27.
The sailboat features a sail area-to-displacement ratio (SA/Disp) of approximately 14.56. This figure suggests moderate performance, implying that the Ericson 31 Independence will likely perform well in moderate to strong breezes but may require more wind to truly get moving in lighter air. A significant ballast-to-displacement ratio of about 0.39 (4,500 lbs of ballast in a 11,400 lb displacement) indicates good stiffness and stability, allowing the boat to stand up to a good breeze without excessive heeling. Owners frequently praise the Ericson 31 Independence for its solid construction and comfortable motion in a seaway, often describing it as much stiffer than smaller Ericson models. It features a fin keel and a transom-hung rudder, contributing to a responsive yet predictable handling experience.
Accommodations and Layout
The interior of the Ericson 31 Independence is designed with comfort and cruising in mind, offering a respectable maximum headroom of 6.08 feet. While specific layouts can vary slightly between individual boats due to owner customizations, the typical arrangement features a conventional cruising interior. This generally includes a V-berth forward, providing a comfortable sleeping area. A head compartment is usually located aft of the V-berth, often to port or starboard.
The main salon typically comprises settees on both sides, which can serve as additional berths, along with a fold-down or fixed table for dining. The galley is often situated aft in the main salon, frequently to starboard, equipped with basic amenities such as a sink, stove, and icebox. Storage is generally ample, with lockers and shelves throughout the cabin. The finish quality often showcases Ericson's typical use of wood trim against fiberglass, providing a warm and classic aesthetic that is both durable and inviting. Grounded search indicates that owners appreciate the well-thought-out use of space for a boat of this size, providing a functional and comfortable living environment for coastal cruising.
Owner's Perspectives
Owners of the Ericson 31 Independence consistently laud its robust construction and dependable nature, often referring to it as a "sturdy design" and a "classic blue water sailing vessel." Many express satisfaction with its solid feel and comfortable motion, particularly when encountering various sea states. The active owner community on platforms like EricsonYachts.org serves as a testament to the boat's enduring appeal, providing valuable resources and shared experiences.
Common strengths highlighted by owners include the boat's overall stability and its capability as a cruising platform. While owners generally praise the boat's design, some discussions in forums touch upon common maintenance aspects typical of boats of this vintage. For example, some owners consider specific original deck fittings prone to eventual leaks, which may require re-bedding over time. Despite these potential issues, the collective sentiment is overwhelmingly positive, with owners appreciating the quality craftsmanship that went into these Bruce King-designed vessels. The Ericson 31 Independence is frequently seen as a "real looker" that offers considerable value for its age and capabilities.
