Moody 33 Mk I Information, Review, Specs

History and Design

The story of the Moody 33 Mk I begins in 1972 when Angus Primrose completed its design, with tooling finished by November of that year. Production commenced in 1973 and continued until 1978. This period marked a significant turning point for Moody Yachts, transitioning from low-volume, semi-custom builds to more mass-produced models using GRP (Glass Reinforced Plastic) construction, which offered greater efficiency and broader market appeal. The builder, A. H. Moody & Sons, already possessed a heritage dating back to 1827, known for prioritizing durability and craftsmanship, an ethos carried into their GRP offerings.

The Moody 33 line saw several iterations, with the Mk I and Mk II being the primary distinctions. While both were designed by Angus Primrose and shared a similar seaworthy hull, the main differences lay in their internal layouts and, for some Mk II models, a larger sail plan. The Mk I is particularly noted for its central aft cabin and a full-width heads compartment situated between the saloon and the forepeak.

Sailing Performance and Handling

With a length overall of 33 feet and a waterline length of 28.51 feet, the Moody 33 Mk I was designed to offer competitive performance for a cruiser of its era. Her reported sail area of 452 square feet combined with a displacement of 10,523 pounds results in a Sail Area to Displacement ratio of approximately 15.06. This ratio suggests a balanced performance profile, not a high-performance racer (which typically have ratios above 24), but capable of moving well in moderate conditions without being overpowered.

The ballast of 3,812 pounds, contributing to a Ballast to Displacement ratio of approximately 0.36, indicates a reasonably stable vessel, capable of standing up to a decent breeze. While not exceptionally stiff, this ratio is typical for a comfortable cruising yacht. The Displacement to Length ratio of approximately 203.46 places the Moody 33 Mk I in the moderate displacement category, balancing a solid feel with a respectable turn of speed for a cruiser.

Anecdotal evidence from owners suggests that while the Moody 33 Mk I is "no race winner" and its windward performance in heavy seas may not be its strongest suit, it "bowls along off the wind in a good breeze." Owners often describe the boat as "sturdy" and "sea kindly," capable of being "surprisingly fast" in the right conditions, with overall sailing performance comparable to other well-regarded cruisers of its time like the Sadler and Contessa.

Accommodations and Layout

The Moody 33 Mk I is celebrated for its generous interior volume, offering considerable space for a boat of 33 feet. As a center-cockpit design, it features a separate aft cabin, which was a highly sought-after attribute for cruising couples and families. The Mk I's interior layout is distinguished by a full-width heads and shower compartment positioned between the saloon and the forward V-berth. The aft cabin itself typically features a central companionway access, setting it apart from the offset access found in later Mk II models.

While specific details on finish quality and materials vary, Moody Yachts generally maintained a reputation for solid construction and robust joinery during this era. Interiors often featured practical, durable finishes with a focus on functional cruising. Owners frequently praise the Moody 33 for its voluminous accommodations, making it a comfortable platform for extended stays aboard.

Owner's Perspectives

Owners of the Moody 33 Mk I frequently commend its "sturdy, sea kindly" nature and impressive interior roominess for its length. The separate aft cabin, enabled by the center cockpit design, is a consistent highlight, offering a private retreat. Many appreciate the boat's ability to handle various sea conditions with a comfortable motion.

However, as with any vessel of its age, certain common issues have been noted. Some early Mk I models experienced "displacement of bulkheads due to light joining method," an issue that potential buyers should investigate. Other recurring maintenance points include the original engine exhaust mixer and steering mechanism, which may be prone to water leaks at their joints over time, necessitating attention. While generally seaworthy, the windward performance in very heavy seas is often cited as a limitation. Despite these points, the Moody 33 Mk I maintains a loyal following, with owners appreciating its robust build and comfortable cruising capabilities.
