In the specialized world of traditional-style cruising, the Eagle II represents a distinct era of trailerable cat-boats designed by the prolific naval architect Ken Hankinson. Originally conceptualized as a larger, more offshore-capable evolution of the standard 16-foot "Eagle" daysailer, the Eagle II (often referred to as the Eagle 23) was marketed through Eagle Sailboats Inc. and via plans from Glen-L Marine. It is characterized by its massive beam, single-sail cat rig, and surprisingly robust displacement for a boat of its length, appealing to sailors who prioritize interior volume and ease of single-handed operation.

The vessel belongs to a family of designs that includes the original 16-foot Eagle (a daysailer) and the flagship Eagle 32, which further expanded the concept into a full-sized coastal cruiser. While many examples were meticulously home-built in wood and epoxy, the production fiberglass hulls built by Eagle Sailboats in the 1970s remain highly sought after on the used market for their structural integrity and "big boat" feel.

Sailing Performance & Handling

The Eagle II is a traditional cat-boat, meaning it carries a single large mainsail on a mast stepped far forward in the bow. This configuration eliminates the complexities of jibs and staysails, making it exceptionally easy to handle for a solo sailor. With a Sail Area to Displacement (SA/Disp) ratio typically hovering around 20.0, the boat is surprisingly powerful in light winds. However, as is common with the hull type, the Eagle II is "beamy" (8-foot beam on a 22.5-foot LOD), providing immense initial stability but requiring early reefing as the breeze freshens.

The handling is defined by the vessel’s heavy displacement (approximately 4,500 lbs) and a Displacement to Length (D/L) ratio of roughly 227. This gives the boat a "sea-kindly" motion, allowing it to punch through chop better than lighter, modern trailer-sailers. Anecdotal evidence from historical tests in Small Boat Journal notes that while the boat tracks well due to its long keel and centerboard, the large mainsail can induce significant weather helm if the sail is not properly trimmed or reefed. The centerboard configuration allows for a shallow draft of just over two feet with the board up, making it an ideal platform for "gunkholing" in thin waters like the Chesapeake Bay or the Florida Keys.

Interior Comfort & Variations

Despite its modest 23-foot length, the Eagle II offers an interior volume comparable to many 27-foot sloops. This is achieved through the cat-boat’s characteristic wide beam and high freeboard. The layout typically features a large V-berth forward, a compact galley area, and twin settees that can serve as additional berths. The lack of a mast compression post in the center of the salon—due to the forward-stepped mast—creates an open, airy feeling that is rare in boats of this size.

Variations of the Eagle II depend largely on whether the boat was a factory production model from Eagle Sailboats or a custom build from Glen-L plans. Production models utilized molded fiberglass liners, while home-built versions often feature extensive brightwork and customized cabinetry. Headroom is generous for a trailerable boat, though it stops short of full standing height for taller sailors. The sibling Eagle 32 takes this interior concept to its logical conclusion, offering a truly liveaboard-capable interior with a private head and standing headroom throughout.

Known Issues & Buyer’s Checklist

Prospective buyers of an Eagle II should focus on three primary technical areas common to this design:

  • Mast Step and Deck Compression: Because the mast is stepped so far forward, the loads on the deck and the mast step are significant. Inspect the foredeck for crazing or sagging, which may indicate core rot or structural fatigue in the step.
  • Centerboard Trunk: The centerboard pivot pin and the trunk itself are prone to wear and leaks. It is essential to inspect the trunk for evidence of "weeping" and to ensure the board operates smoothly without excessive lateral play.
  • Weather Helm & Sail Condition: Due to the single-sail rig, the condition of the mainsail is critical. A "blown out" or baggy sail will significantly exacerbate the boat’s natural tendency toward weather helm. If the boat rounds up aggressively in moderate gusts, a new, flat-cut sail may be required.
  • Wood-Epoxy Specifics: For home-built versions, a thorough moisture meter test of the hull and transom is required to ensure the epoxy encapsulation has remained intact over the decades.

Community & Resources

The primary technical resource for the Eagle II remains the Glen-L Marine technical archives, which still provide support and plans for the design. Owners often congregate in broader cat-boat associations, such as the Catboat Association, which maintains a wealth of knowledge on handling techniques and restoration tips for the Hankinson-designed Eagle series.

The Verdict

The Eagle II is a rugged, voluminous cruiser that defies the typical limitations of a 23-foot boat, offering a unique blend of traditional aesthetics and modern fiberglass convenience.

Pros:

  • Exceptional interior volume for its length.
  • Simple, easy-to-manage cat rig for solo sailing.
  • Shallow draft ideal for coastal exploring.
  • Stable and sea-kindly motion in a seaway.

Cons:

  • Pronounced weather helm if not reefed early.
  • Large mainsail can be heavy to hoist without a winch.
  • Limited performance to windward compared to a modern sloop.
  • High windage due to the tall freeboard and wide beam.
