The model's history is inextricably linked with a classic corporate trademark dispute. Shortly after its introduction, Morgan Yachts (builders of the unrelated, high-performance North American 40) threatened a lawsuit over the "North American" name. Consequently, Glastron reorganized and rebranded the sailing division as Spirit Yachts. After 1978, the vessel was built in Austin, Texas, and marketed as the Spirit 23 until production ceased in 1981. Despite the sudden name change and minor cosmetic updates, the North American 23 and the Spirit 23 are structurally identical, sharing the same hull lines, construction techniques, and highly functional layout.
Design Brief & Intent
The North American 23 was designed to serve the needs of inland lake, bay, and coastal sailors who required a boat small enough to trailer behind a standard family vehicle but large enough to sleep a family of four for a long weekend. In an era dominated by Spartan utility boats, Finch prioritized interior volume. The hull features a relatively wide beam of 7.92 feet carried well aft, creating a stable platform with a surprisingly spacious cabin for a 23-footer.
To maximize the boat's utility at anchor, the builder featured an optional fiberglass "pop-top" companionway hatch. When raised, this innovative system transforms the standard sitting headroom of roughly 4.3 feet into an impressive 6 feet 2 inches of standing headroom. Below decks, the joinery reflects Glastron’s fiberglass manufacturing prowess; a drop-in fiberglass liner provides structural rigidity, accented by warm teak bulkheads and trim. The layout is highly efficient, utilizing a forward V-berth, two long facing salon settees, and a clever slide-out galley drawer that houses a sink, fresh water tank, and space for a portable stove.
Variations & Configurations
While the vast majority of North American 23s were delivered as masthead sloops with a swing-keel centerboard configuration, two distinct underwater profiles exist:
- Centerboard Variant: This is the standard model, featuring an 800-pound shallow cast-iron stub keel paired with a retractable fiberglass centerboard. With the board retracted, the boat draws a mere 2.0 feet, allowing owners to beach the vessel, explore shallow estuaries, and easily guide the hull onto a trailer. When the board is fully lowered, draft increases to 5.0 feet, providing the necessary lateral resistance to track effectively to windward.
- Fixed Keel Variant (Spirit 23 K): Primarily sold under the Spirit Yachts banner, the "K" designation features a fixed fin keel drawing 3.5 feet. It carries a heavier, 1,150-pound lead ballast, increasing total displacement to 3,150 pounds. This variant was paired with a taller rig, a mid-cockpit mainsail traveler, and a solid fiberglass rudder, appealing to sailors looking for enhanced stiffness and simplified maintenance at the expense of easy trailering.
Sailing Performance & Handling
The centerboard version of the North American 23 displays a highly responsive, light-displacement character on the water. Its Displacement-to-Length (D/L) ratio of 156.25 categorizes it as a light boat that is easy to drive, accelerating quickly in light winds and performing admirably off the wind. This responsiveness is supported by a respectable Sail Area-to-Displacement (SA/D) ratio of 17.31, which provides plenty of horsepower to move the hull in under-10-knot breezes without resorting to massive overlapping genoas.
With a Ballast-to-Displacement (B/D) ratio of 28.57%, the centerboard version is relatively tender when compared to dedicated offshore pocket cruisers. It is a boat that communicates early, heeling quickly to its sailing lines before settling onto its hard turn of bilge. Because of this, prudent skippers typically tuck a reef into the mainsail when true wind speeds climb past 12 to 14 knots to maintain a light helm and prevent excessive leeway. Its Capsize Screening Ratio of 2.25 and a light Comfort Ratio of 13.15 mathematically confirm what its design dictates: the boat is a lively day-sailor and weekend coastal cruiser. It will handle choppy bay waters with a predictable, active motion but is not designed or ballasted for offshore voyaging.
Market Snapshot & Economics
Decades after the final hull left the Austin production line, the North American 23 represents an exceptionally accessible entry point into the cruising lifestyle. Because they were built in large numbers by a major manufacturer, they remain a common sight in the used trailer-sailer market, particularly across the Midwest, Gulf Coast, and Great Lakes regions.
The vessel generally commands a value-oriented price, making it highly competitive with contemporary designs like the Catalina 22, O'Day 23, or Aquarius 23. The economics of owning a North American 23 are highly favorable due to its trailerability; owners can bypass slip and haul-out fees entirely by storing the boat on a trailer in a driveway or dry-storage yard. Because the boat relies on a simple transom-mounted outboard motor (typically between 6 and 9.9 horsepower) rather than a complex inboard diesel, mechanical maintenance costs are minimal and easily within the scope of a handy DIY owner.
Known Issues & Triage
Potential buyers should inspect vintage models for several common structural and mechanical vulnerabilities:
- Deck Core Softness: Like most production boats of its era, the deck was constructed using a balsa wood core sandwiched between layers of fiberglass. Over decades, water can bypass aging sealant around the chainplates, deck-stepped mast organizer, stanchions, and bow pulpit. This leads to localized wood rot and soft spots, which require core replacement and re-bedding of the hardware.
- Mast Step Compression: The mast is stepped on the deck, with its downward load transferred to an internal bulkheaded compression post. If moisture has entered the deck laminate directly beneath the mast shoe, the core can collapse, resulting in a sagging deck, loose standing rigging, and poor mast tuning.
- Centerboard Pendant and Pin Wear: On the centerboard model, the stainless steel wire pendant used to lift the board, along with its associated sheaves and the main pivot pin, are subject to heavy wear and galvanic corrosion. A neglected pendant can snap, trapping the centerboard in the down position. If the board clunks or shifts excessively while under sail, the fiberglass trunk's pivot pin bushings are likely worn down and require replacement.
- Pop-Top Gasket Failure: The optional pop-top mechanism relies on a canvas or vinyl enclosure with snap fasteners and rubber seals. In many surviving examples, these textiles have deteriorated, resulting in significant rainwater leaks into the main cabin if they have not been renewed.
Modernization & Upgrades
Many dedicated owners have kept these pocket cruisers remarkably modern with several common, high-impact upgrades:
- Electrical Retrofitting: The original DC electrical systems were minimal, often consisting of just a few incandescent interior dome lights and basic navigation lights run on a single lead-acid battery. Modern owners commonly replace this wiring with marine-grade tinned wire, convert all fixtures to low-draw LEDs, and install a compact, lightweight 50Ah or 100Ah LiFePO4 (lithium iron phosphate) battery.
- Solar Power Integration: Because the boat relies on pull-start outboard engines that rarely feature high-output charging alternators, owners frequently mount a small 50-watt to 100-watt solar panel on the stern rail or lazarette hatch. Paired with an MPPT controller, this provides more than enough passive power to run cabin lights, charge mobile devices, and power a small portable cooler.
- Rigging and Sailing Hardware: Replacing aging stainless steel standing rigging is a priority for safe sailing. Many owners upgrade from old-fashioned, high-friction wire-to-rope halyards to modern, low-stretch Dyneema lines. Adding a modern headsail roller-furling system vastly simplifies short-handed sailing on this lively hull.
The Verdict
The North American 23 remains a highly successful example of a 1970s trailerable pocket cruiser. For sailors seeking an affordable, stable, and easily managed boat with genuine overnight capabilities, its clever pop-top design and spacious interior layout are tough to match in this size bracket.
Pros

- Responsive and lively sailing performance in light-to-moderate air.
- Simple, reliable, and low-cost systems that are ideal for hands-on, DIY owners.
Cons
- Tender hull form requires early reefing when winds exceed 12 knots.
- Not suitable for heavy offshore work or blue-water voyaging.
- Common vintage sailboat vulnerabilities, including balsa core deck rot and centerboard assembly wear.
