Design Brief & Intent
The Great Lakes 21 was designed to meet the specific requirements of the Mentor Harbor Yacht Club (MHYC) near Cleveland, Ohio. In the late 1930s, active club racer Harold Kneen sought a high-performing design to race on the challenging, short-chop waters of Lake Erie. Having observed how Maine-built Hodgdon sloops outperformed popular Star class boats under certain racing conditions, Kneen commissioned Charles Hodgdon to draw a new 21-foot keelboat. The resulting boat, Delilah (hull number one), launched in 1939 and immediately proved its capability as an open-water racer.
Unlike its heavier contemporaries, the Great Lakes 21 was designed as a pure, open-cockpit day racer with no cabin trunk or accommodations. The lack of a cabin maximized deck space and allowed for an ergonomically clean cockpit layout, comfortably accommodating a racing crew. The hull shape combined a relatively high bow profile with sharp forward sections and a moderate beam of 5 feet, 9 inches to keep the crew dry and slice through heavy freshwater chop. The finish quality reflected the classic craftsmanship of the Hodgdon Brothers, showcasing beautiful woodwork and elegant, low-profile lines.
Variations & Configurations
Over its production lifespan, the Great Lakes 21 underwent two major manufacturing transitions, evolving alongside 20th-century boatbuilding technology. The original batch of sloops built by Hodgdon Brothers in Maine utilized traditional carvel wood construction. These wooden boats featured elegant plank-on-frame hulls that required meticulous upkeep but offered classic aesthetics.
As the fleet's popularity exploded across the American Midwest, production shifted to the newly formed Douglass & McLeod (D&M) yard in Grand River, Ohio. Douglass & McLeod built the hulls using molded mahogany plywood supplied by U.S. Molded Shapes. To expand the model's marketing appeal after World War II, the class rebranded the boat as the International 21 (I-21). In the 1950s and 1960s, Douglass & McLeod experimented with early fiberglass construction, introducing a GRP version of the hull. Across all generations and hull materials, the core configurations remained highly consistent: a fractional sloop rig, a fixed fin keel drawing 3 feet, 5 inches, and an open deck plan.
Sailing Performance & Handling
The Great Lakes 21's sailing characteristics are defined by its light, high-powered design. With a displacement of 1,800 pounds and a light displacement-to-length (D/L) ratio of 130.48, the hull is easily driven and responds instantly to light puffs. Its generous sail area of approximately 200 square feet yields a high sail area-to-displacement (SA/D) ratio of 21.62, placing it firmly in the category of high-performance vintage day racers.
On the water, the boat is lively and quick to accelerate but requires active crew weight management, as its narrow beam and light displacement mean it is not overly stiff. This responsiveness makes it a highly engaging tactical racer. While its low comfort ratio of 14.13 indicates a motion that is active and closely aligned with a sporty dinghy rather than a heavy cruiser, its high-sided bow profile provides surprising dryness in a heavy chop. Its capsize screening formula of 1.89 suggests a stable footprint for an open day-sailer, though it remains a boat that relies on skilled helm control and crew trim when pushed hard in heavy air.
Market Snapshot & Economics
Today, the Great Lakes 21 is a rare and highly prized classic. Because of the limited numbers produced across its wood, molded plywood, and fiberglass iterations, boats rarely appear on the open brokerage market. Instead, transactions occur privately within tight-knit regional classic yacht circles, such as the Boothbay Harbor One Design Association or Midwestern yacht clubs.
The economics of owning a Great Lakes 21 are heavily dictated by its hull material. Wooden and molded plywood specimens command a restoration premium, often requiring the specialized services of classic boatyards, such as the Riverside Boat Company or Southport Island Marine, to maintain structural integrity. Original wooden hulls require significant, ongoing maintenance budgets to preserve their frames, fasteners, and varnished brightwork. Fiberglass models, though exceptionally rare due to the 1971 fire that destroyed the Douglass & McLeod factory, represent a much more accessible ownership proposition in terms of seasonal maintenance.
Preservation & Legacy Maintenance
Because the Great Lakes 21 was built during transition eras of boatbuilding, structural preservation is the primary focus for current caretakers.
- Wooden Hulls: Original carvel-planked Hodgdon hulls are prone to typical freshwater deterioration. Key inspection areas include the keel-to-hull joint, where traditional fasteners can corrode or back out, and freshwater rot in the white oak frames.
- Molded Plywood Hulls: The molded mahogany plywood models produced by Douglass & McLeod must be monitored closely for delamination. Moisture ingress through chipped paint or varnish can compromise the adhesive layers, requiring extensive epoxy injection or localized veneer replacement.
- Fiberglass Hulls: For the rare GRP editions, deck-to-hull joints and chainplate bulkheads are the primary points of failure, requiring reinforcement to handle the rig loads of the highly tensioned fractional spar.
The Verdict
The Great Lakes 21 is a historic, high-performance vintage sloop that holds a storied position in American yachting history. While it offers an incredibly rewarding, tactile sailing experience and gorgeous classic lines, it is best suited for dedicated caretakers who are willing to invest the time and capital required to preserve a piece of maritime heritage.
Pros
- Exquisite classic lines and historical pedigree as a design by Charles Hodgdon.
- Extremely lively and responsive performance, especially in light air and inland chop.
- Large, ergonomic, open-cockpit layout that is perfect for day racing and socialization.
- Highly active and supportive enthusiast associations in New England and the Midwest.
Cons
- Extremely rare, making it difficult to source parts, sister ships, or boats for sale.
- High-maintenance hull materials (wood and molded plywood) require specialized, costly preservation.
- Completely open design provides zero overnight accommodations or weather shelter.
- Lacks the modern stability of heavy-bulb keelboats, demanding active crew work in heavy air.
