The Thom Cat 23 is a distinctive gaff-rigged catboat, celebrated for its classic lines and versatile performance as a coastal cruiser and day sailor. Originally known as the Menger Cat 23, this model represents a continuation of traditional American sailboat design. The boat was designed by the father-and-son team of Bill and Andrew Menger, building upon the foundations of Francis Sweisguth's Americat 22 design. Production of the Thom Cat 23 by Thompson Boatworks commenced in 2006 and continued until 2010, ensuring the legacy of a beloved design.

The lineage of the Thom Cat 23 traces back to the Menger Cat 23, which was originally built by Menger Boat Works from 1990 to 2004. Thompson Boatworks, established in 2006 in West Sayville, New York, acquired the original molds of the Menger Catboats, allowing them to continue producing these iconic vessels. This commitment highlights Thompson Boatworks' founding vision, which is deeply rooted in craftsmanship and a desire to preserve traditional sailing designs for new generations of enthusiasts. The Menger design philosophy, upheld by Thompson Boatworks, emphasizes broad beam, shallow draft, and gaff-rigged simplicity, qualities that contribute to comfortable and stable sailing. The Thom Cat 23, therefore, embodies a design ethos focused on ease of handling and a connection to maritime heritage.
Sailing Performance and Handling
With a length overall of 22.5 feet and a waterline length of 21.33 feet, the Thom Cat 23 is designed for a balance of stability and performance. Its reported sail area of 435 square feet coupled with a displacement of 6,500 pounds yields a Sail Area to Displacement Ratio (SA/D) of approximately 20.0. This ratio suggests a boat with good performance in lighter air conditions, capable of moving efficiently even when the breeze is modest.
The Displacement to Length Ratio (D/L) of around 299 categorizes the Thom Cat 23 as a moderate to heavy displacement vessel for its size. This indicates a robust and stable hull, providing a comfortable motion in a seaway, characteristic of a capable cruiser. The Thom Cat 23 features a centerboard keel, allowing for a minimum draft of 2.5 feet and a maximum draft of 5.5 feet. This design enables access to shallow coastal waters and coves while offering increased stability and windward performance with the board lowered. Anecdotal evidence suggests the Thom Cat 23 is a "moderate weight sailboat which is a high performer" and "very stable / stiff." It possesses a gaff-head cat rigging, known for its powerful and easily managed sail plan, making it a good choice for single-handed sailing.
Accommodations and Layout
The interior of the Thom Cat 23 reflects its primary role as a day sailer and coastal cruiser, emphasizing practicality over extensive private cabins. With no dedicated cabins, the layout is typically open, providing a functional space for day trips or simple overnight stays. While specific headroom figures are not always detailed for this model, the design prioritizes a spacious feel within its compact footprint. The emphasis is on an uncluttered environment, allowing for flexibility in its use, whether for storage, seating, or basic sleeping arrangements, catering to those who appreciate a less complex cruising experience.
