Dolphin 47 (Alden) Information, Review, Specs

History and Design

The creation of the Dolphin 47, design number 1024, unfolded during a period when Hodgdon Bros. was actively building a variety of vessels, upholding its long-standing commitment to craftsmanship and custom quality that dates back to 1816. John G. Alden's design philosophy centered on crafting yachts that were not only quick enough for their purpose but also supremely comfortable and a pure joy to handle, emphasizing seakindliness in their motion. This ethos is clearly reflected in the Dolphin 47, which was built as a heavy-displacement, long-keel monohull designed to stand up to challenging conditions.

A relatively exclusive model, only 13 Alden Dolphin 47s were built, and remarkably, all are reported to be still actively sailing, underscoring their durable construction. The boat was notably a cutter-rigged ketch, offering a versatile sail plan suitable for various wind conditions, a hallmark of practical offshore design.

Sailing Performance and Handling

The Alden Dolphin 47's design characteristics point to a vessel built for stability and comfortable passage-making rather than outright speed. With a calculated Sail Area to Displacement ratio of approximately 13.88, the Dolphin 47 is not primarily a light-air performer but is designed to carry sail effectively in moderate to strong winds. Her Ballast to Displacement ratio of around 37% indicates a moderate level of stiffness, allowing her to stand up well to a breeze and provide a secure, upright motion. The high Displacement to Length ratio, calculated at approximately 355.5, firmly places her in the category of a heavy, traditional displacement cruiser. This heavy displacement, combined with a full long keel, contributes significantly to her renowned seakindliness and directional stability, making her a predictable and comfortable boat in a seaway. Owners and enthusiasts often describe the Dolphin 47 as "stout" and possessing "solid construction," qualities highly valued in a blue-water cruiser.

Accommodations and Layout

While specific interior layout details can vary between individual vessels due to custom finishes and subsequent owner modifications, the Alden Dolphin 47 was generally configured as a spacious and functional offshore cruiser. Reviews and forum discussions suggest that these boats typically featured a robust interior with significant use of wood, such as teak, reflecting the traditional craftsmanship of the era.

Given her generous beam of 13.25 feet and long waterline, the interior offers ample volume for comfortable living during extended voyages. Accommodations would typically include a V-berth forward, a main salon with settees and a dining area, a well-equipped galley, and a navigation station. With a substantial fresh water capacity of 200 gallons and a fuel capacity of 200 gallons for her Perkins diesel engine, she was equipped for prolonged periods at sea. Owners often praise the "beautiful interior" of these classic vessels.

Owner's Perspectives

Owners of the Alden Dolphin 47 consistently laud its robust construction and solid design, emphasizing its capabilities as a true blue-water cruiser. The fact that all 13 original hulls are still actively sailing speaks volumes about their inherent durability and the quality of their build. The design's strengths are often cited as its comfortable motion in a seaway, excellent stability, and dependable handling characteristics. Many owners undertake extensive restoration projects, highlighting the boat's classic appeal and the value placed on preserving these well-regarded vessels. While the initial purchase may be more affordable than newer boats, owners acknowledge that, like any vintage yacht, a Dolphin 47 may require significant investment in updating systems, rigging, and sails. The collaborative spirit among owners on forums further underscores the enduring appeal and community around this classic Alden design.
