The Companion 21 is a robust, traditionally styled pocket cruiser that emerged from the Stonington, Connecticut, workshop of Trump Yachts during the 1970s. Designed by the company’s founder, Aborn Smith Jr., the vessel represents a specific era of New England boatbuilding where durability and a "big boat" feel were prioritized over lightweight racing performance. With a length overall of approximately 21 feet, it was marketed as a manageable step up for sailors transitioning from open dinghies to overnight-capable coastal vessels. The boat shares the distinctive DNA of its larger siblings, the Margaret D (Trump 25) and the Trump 27, characterized by heavy fiberglass layups and a design philosophy that favored stability in the choppy waters of Long Island Sound.

Sailing Performance & Handling
The Companion 21 is frequently described as a "stiff" boat, a characteristic derived from its relatively high displacement and traditional hull form. While it lacks the twitchy acceleration of modern fin-keel daysailers, it offers a sense of security and "sea-kindliness" that is rare in vessels of this size. The boat’s tracking is aided by a substantial keel configuration, which allows it to hold a course with minimal helm correction.
In terms of handling, the Companion 21 excels in moderate to heavy breezes. While it may struggle in light air due to its wetted surface area and weight, it carries sail longer than its competitors as the wind increases. Owner anecdotes from the New England region often highlight its ability to punch through a short chop without the pounding typical of flatter-bottomed designs. The rigging is typically a simple masthead sloop, making it an ideal platform for single-handed sailing or for teaching novices the fundamentals of sail trim.
Interior Comfort & Variations
Despite its modest footprint, the Companion 21 features a functional cuddy cabin designed for weekend coastal hops. The layout is rudimentary but purposeful, typically consisting of a V-berth forward and two short settee berths. Headroom is limited, as is standard for a 21-foot "pocket" cruiser, necessitating a sitting-only environment once below decks. However, the use of teak trim and the solid feel of the hull construction provide a sense of traditional maritime aesthetics.
Variations of the design occasionally surface with slight modifications to the cockpit locker layouts or interior cabinetry, reflecting the semi-custom nature of Trump Yachts' production. Because Aborn Smith Jr. transitioned the company into Atlantic Yacht Services in 1984, later versions of the hull may feature updated hardware or slightly different ballast configurations, though the core hull shape remained consistent across its production run.
Popular Mentions & Media
While the Companion 21 did not achieve the mass-market fame of brands like Catalina, it maintains a quiet, prestigious reputation in Connecticut maritime history. Mention of the builder and its founder, Aborn Smith Jr., can be found in historical records of Stonington's industrial evolution. The Stonington Historical Society archives preserve the legacy of local builders like Smith, who transitioned from the automotive sector to create a boutique line of sailboats that defined the local harbor scene for over a decade.
Known Issues & Buyer’s Checklist
Potential buyers should focus their inspections on the common age-related ailments of 1970s fiberglass construction. Use the following checklist when evaluating a Companion 21:
- Deck-to-Hull Joint: Scrutinize the joint for leaks, as the original bedding compounds may have dried and shrunk over the decades, leading to water ingress in the cabin.
- Core Integrity: Trump Yachts utilized wood coring in some deck areas. A moisture meter is essential to check for delamination or rot, particularly around high-stress areas like chainplates and stanchion bases.
- Rudder Hardware: The rudder assembly and pintles are known wear points. The heavy displacement of the hull puts considerable stress on the steering gear in heavy weather, and any excessive play should be addressed.
- Keel Attachment: If the vessel features a fixed keel, inspect the hull-to-keel joint for any signs of "smiling" (stress cracks), which may indicate the need for new keel bolts or re-bedding.
Community & Resources
There is no longer a formal manufacturer-backed association for Trump Yachts. However, technical information is most reliably sourced through the small but dedicated community of "Trump Yacht" enthusiasts in the Long Island Sound area. Local maritime heritage groups in Stonington and New London remain the best repositories for original design philosophies and builder context regarding Aborn Smith Jr.'s work.
The Verdict
The Companion 21 is a stout, "small-but-mighty" cruiser that offers more security and traditional charm than most boats in its size class.
Pros:
- Exceptionally sturdy construction with a focus on durability.
- Predictable handling and excellent stability in a breeze.
- Manageable for single-handed sailing and beginner sailors.
