Sea Bird 37 MS Information, Review, Specs

The Sea Bird 37 MS began its production run in 1973, emerging from the boatyards of Cooper Enterprises Inc. in Port Coquitlam, British Columbia. The company, under the leadership of Forbes Cooper, was dedicated to pioneering yacht building in the region, initially producing licensed American sailboat designs before expanding into its own line of well-regarded vessels. The Sea Bird 37 MS itself is a notable evolution, based on the original Sea Bird 37 hull, but distinguished by a newly designed deck by Forbes Cooper, marking its identity as a motorsailer (MS) variant. While the hull design was a collaborative effort, Cooper's involvement in the deck design underscores the builder's commitment to adapting and refining designs for specific market needs during an era known for robust construction.

Sailing Performance and Handling

The Sea Bird 37 MS is characterized by its substantial build and emphasis on comfort and stability over outright speed. With a reported sail area of 560 sq ft, a displacement of 18,000 lbs, and a waterline length of 32.5 feet, its calculated sail area to displacement ratio (SA/D) is approximately 13.03. This relatively low ratio suggests that the vessel is not designed for spirited performance in light winds, indicating a more relaxed pace under sail. The ballast to displacement ratio (B/D) stands at about 0.33, which, while not as high as dedicated racing yachts, contributes to a stable motion, particularly in combination with its long keel hull type. Furthermore, a high displacement to length ratio (D/L) of approximately 524.37 firmly places the Sea Bird 37 MS in the heavy displacement category, signifying a robust and traditional cruiser built to handle challenging sea conditions with a comfortable motion. Owners have noted that the boat's upwind performance can be "painful to bear," reinforcing its design as a heavy-displacement motorsailer where motoring performance often complements or takes precedence over pure sailing efficiency, especially when beating into seas. Described as a "robust vessel," the Sea Bird 37 MS is generally considered capable and seaworthy.

Accommodations and Layout

The interior of the Cooper Sea Bird 37 MS is designed for liveability and extended cruising, a hallmark of motorsailers. While specific headroom figures are not readily available in the detailed specifications, online reviews and owner descriptions indicate a bright and thoughtfully designed layout. The vessel typically offers sleeping accommodations for four comfortably, with options to extend to six, often configured with two double berths and two single berths. A significant feature is the presence of an aft cabin, which often includes its own head (bathroom), providing enhanced privacy and convenience, particularly on longer voyages or with multiple crew members. Many Sea Bird 37 MS models are also recognized for featuring an enclosed center cockpit or pilothouse arrangement, which offers excellent shelter and visibility, making them well-suited for cruising in various climates and providing a secure helm station. The hull is constructed from solid fiberglass, contributing to the boat's reputation for durability. The vessel carries substantial tankage, with 100 gallons of fuel capacity and 100 gallons of water capacity, supporting self-sufficiency for longer periods away from port. Power is typically provided by a 50 hp Perkins diesel engine, ensuring reliable propulsion.

Owner's Perspectives

Owners of the Cooper Sea Bird 37 MS frequently highlight its solid construction and suitability for comfortable cruising. Many appreciate the robust nature of the heavy-displacement hull, which provides a steady and reassuring motion in a seaway. The enclosed center cockpit or pilothouse configuration is often praised for offering excellent protection from the elements, enhancing comfort during watchkeeping or in inclement weather. However, a recurring theme in owner discussions revolves around the boat's sailing performance, particularly when sailing to windward. Some owners find its upwind capability to be less than exhilarating, indicating a compromise often accepted in motorsailer designs where motoring efficiency and interior volume are prioritized. Owners may also note issues related to water ingress in the cockpit when beating into heavy seas. Despite these sailing characteristics, the Sea Bird 37 MS maintains a reputation as a dependable and well-built vessel for those prioritizing comfort, stability, and motorsailing capability for their cruising adventures.
