The SturDee Cat, a 14foot fiberglass catboat designed by the esteemed naval architect Edson Schock, represents a harmonious blend of traditional New England aesthetics and modern, lowmaintenance construction. Produced by the SturDee Boat Co. in Tiverton, Rhode Island, this vessel is a direct descendant of the working catboats that once dominated the coastal waters of the Northeast. Unlike many of its woodplanked ancestors, the SturDee Cat features a handlaid fiberglass hull, ensuring longevity and structural integrity while retaining the classic lines—including the characteristic wide beam and barndoor rudder—that define the genre. As a "big" small boat, it offers a level of stability and cockpit volume that belies its 14foot length, making it a favorite for family daysailing and solo exploration in thin water.

Sailing Performance & Handling

The sailing characteristics of the Stur-Dee Cat are defined by its remarkable stability and the simplicity of its single-sail plan. With a beam of 6' 6" on a 14' 2" waterline, the boat possesses an exceptionally high initial stability, which provides a sense of security for novice sailors and allows for a comfortable, upright sailing posture. According to technical specifications provided by Stur-Dee Boat Co., the vessel utilizes a centerboard design, drawing only 6 inches with the board up. This allows the Cat to venture into shallow marshes and tidal creeks where deeper-draft monohulls cannot follow.

While traditional catboats often employ a gaff rig, the Stur-Dee Cat is frequently configured with a modern Marconi rig. This triangular sail plan simplifies tacking and reduces the weight aloft, though it maintains the massive sail area relative to the hull length that provides excellent light-air performance. Handling is generally described as "forgiving," though, like all catboats, the Stur-Dee Cat can develop significant weather helm if over-canvassed in a blow. This is managed by reefing early or easing the sheet to let the large barn-door rudder maintain control. The boat tracks well due to its hull shape and the substantial surface area of the centerboard when deployed to its 3' 6" maximum depth.

The Stur-Dee Cat and its builder have enjoyed a storied reputation within the nautical press for decades. A seminal profile in Soundings Magazine titled "Happiness is 50 Years of Stur-Dee Boats" highlighted the company's commitment to Ernie Gavin’s original vision of seaworthy, no-nonsense vessels. The model is a frequent subject of discussion in regional maritime publications like Points East and Small Boats Magazine, where it is often cited as a benchmark for the fiberglass catboat revival. Its cultural footprint is most visible in the harbors of Narragansett Bay and Cape Cod, where it remains a symbol of the enduring appeal of the Rhode Island boatbuilding tradition.

Known Issues & Buyer’s Checklist

When inspecting a pre-owned Stur-Dee Cat, the primary focus should be on the woodwork and the centerboard trunk. Because these boats often feature significant teak or mahogany trim, neglected brightwork is a common cosmetic issue that can lead to wood rot if the bedding compounds have failed.

  • Centerboard Trunk and Pivot: Inspect the centerboard trunk for cracks or leaks, particularly around the pivot bolt. In older models, the centerboard itself (if metal) should be checked for corrosion, while fiberglass boards should be inspected for delamination or "blooming" from water ingress.
  • Mast Step Integrity: The mast on a catboat is stepped far forward, placing unique stress on the forward deck and keel structure. Check the mast step for signs of compression or hair-line fracturing in the gelcoat, which may indicate structural fatigue.
  • Gudgeons and Pintles: The oversized "barn-door" rudder exerts significant leverage on the transom. Ensure that the gudgeons and pintles are securely fastened and that the transom shows no signs of flexing or core saturation around the mounting points.
  • Gelcoat Condition: While the hand-laid hulls are robust, older Stur-Dee models kept on moorings may exhibit osmotic blistering if they were not protected with a barrier coat.

Community & Resources

Owners of the Stur-Dee Cat are often active participants in the broader catboat community. The Catboat Association is the premier technical and social resource for these vessels, providing a wealth of information on rig tuning, historical research, and regional regattas. Because the Stur-Dee Boat Co. remains a family-operated business in Tiverton, RI, the builder themselves serves as the primary technical wiki, often providing replacement parts and restoration advice directly to owners of vintage hulls.

The Verdict

The Stur-Dee Cat is a masterclass in functional traditionalism, offering the charm of a 19th-century design with the ease of 21st-century materials. It is an ideal vessel for those who value stability and shallow-water access over raw racing speed.

Pros:

  • Exceptional Stability: The wide beam makes it nearly impossible to capsize under normal conditions.
  • Ease of Use: The single-sail rig is perfect for solo sailors or those who want to focus on the scenery rather than complex trimming.
  • Heritage Craftsmanship: Built by a multi-generational family business with a focus on durability.
  • Shallow Draft: The 6-inch board-up draft allows for "gunkholing" in the skinniest of waters.

Cons:

  • Weather Helm: Can become heavy on the tiller in high winds if the sail is not reefed.
  • Limited Upwind Ability: Like most catboats, it will not point as high as a modern sloop-rigged daysailer.
  • Aesthetic Maintenance: The classic wood trim requires regular attention to maintain its appearance.
