The Mayflower 1620 is a quintessential English merchant vessel of the late Elizabethan and early Jacobean eras, characterized by its "v-shaped" hull and three-masted square rig. While the original ship was a working "sweet ship" (so named for its history in the wine trade, which helped neutralize the smell of bilge water), its technical legacy is preserved today through the meticulous research of naval architect William A. Baker and the Plimoth Patuxet Museums. Designated as a "merchantman" of roughly 180 tons, the 1620 model represents a transition in maritime design between the bulky carracks of the 16th century and the more refined galleons of the 17th. It features a high-profile "poop deck" at the stern and a forecastle at the bow, designed more for cargo capacity and stability in the North Atlantic than for speed or windward performance.

Sailing Performance & Handling
The sailing characteristics of the Mayflower 1620 are defined by its square-rigged configuration and its reliance on a "whipstaff" for steering, rather than a modern wheel. According to sea trials conducted by the Mayflower II replica, the vessel is remarkably sea-kindly in heavy weather due to its deep-V hull and heavy rock ballast, though it suffers from significant leeway when attempting to beat to windward. The sail plan consists of a square-rigged foremast and mainmast, complemented by a lateen-rigged mizzenmast that assists with trim and maneuverability.
Handing is notably labor-intensive; the absence of mechanical winches means that every adjustment to the heavy canvas sails requires coordinated manual labor from the crew. The ship’s tracking is stable in a following wind, but its "apple-cheeked" bow and high freeboard create significant windage, making it difficult to maintain a course in crosswinds. Technical assessments suggest the boat could rarely sail closer than six points (67.5 degrees) to the wind, a limitation that famously extended its 1620 crossing to 66 grueling days.
Interior Comfort & Variations
The interior of the 1620 model is divided into three primary functional areas: the Great Cabin, the Steerage, and the "tween deck." The Great Cabin, located at the stern, provides the most refined accommodation, featuring the only significant natural light and relative privacy for the ship’s Master. In contrast, the Steerage is a cramped, functional space where the helmsman operates the whipstaff while looking through a "bittacle" to the deck above.
The "tween deck" (the space between the main deck and the hold) is where the majority of passengers were housed during the historic 1620 voyage. With a ceiling height of roughly five to five-and-a-half feet, it offers no standing headroom for most adults. This area is completely unventilated and lacks windows, relying on small "scuttles" that are often sealed during heavy weather. In terms of siblings, the Speedwell served as the smaller, ill-fated companion to the Mayflower; however, the Mayflower's specific hull was typical of the mid-sized merchant fleet of the time, such as the Discovery and Susan Constant used in the Jamestown expedition.
Popular Mentions & Media
The Mayflower 1620 occupies a singular position in maritime history and popular culture. Its most significant modern representation is the Mayflower II, a full-scale replica built in Brixham, England, which sailed to the United States in 1957. This voyage was heavily documented by National Geographic, providing the first modern technical insights into how a 17th-century merchantman behaves in open ocean conditions. The ship’s architectural plans, reconstructed by William A. Baker, have since become the global standard for historical shipbuilders and modelers.
Known Issues & Buyer’s Checklist
For those involved in the maintenance of historical replicas or studying the 1620 design, several high-signal technical issues are inherent to this specific hull type:
- Tumblehome and Water Retention: The extreme "tumblehome" (the inward curve of the upper hull) can cause water to pool in the channels and chain-plates, leading to localized rot in the oak timbers if not frequently treated with pine tar and oakum.
- Whipstaff Mechanical Failure: The whipstaff is a simple lever-to-tiller connection; the "gooseneck" fitting and the leather "boot" that seals the deck opening are prone to wear and leakage.
- Rigging Tension: The use of deadeyes and lanyards rather than turnbuckles means the rig requires constant seasonal adjustment, as natural hemp or manila lines stretch and shrink with humidity.
- Hogging of the Keel: Given the age of the design and the weight of the high stern, these vessels are prone to "hogging," where the ends of the ship drop relative to the middle, potentially compromising the integrity of the keel.
Community & Resources
The primary authority for the technical preservation and history of this vessel is the Mayflower Society (The General Society of Mayflower Descendants) and the Plimoth Patuxet Museums, which maintains the world's most accurate sailing reconstruction. Technical drawings and historical research papers are often published by the Society for Nautical Research, which provides peer-reviewed data on 17th-century naval architecture.
The Verdict
The Mayflower 1620 is a masterpiece of Jacobean merchant engineering, prioritized for volume and durability over speed. It remains a benchmark for the "merchantman" class of the 1600s.
Pros:
- Exceptional stability in heavy North Atlantic swells.
- Massive interior volume for a vessel under 100 feet.
- Proven durability in cold-water environments.
Cons:
- Extremely poor windward performance (cannot "point" high).
- Sub-six-foot headroom in the primary living quarters.
- High maintenance requirements for the traditional oak and hemp construction.
