About the HINCKLEY 21
Carl Alberg was working for John Alden at this time. Alden design #761. Updated in 1948 (#839). Design #839: # built: 4 LOA: 29.25'/8.92m LWL: 21.08'/6.43m Beam: 8'/2.44m Draft: 4.58'/1.4m Displacement: 9560 lbs/4336 kg
The Hinckley 21 is a rare, high-quality classic designed by Carl Alberg/Alden and built by Henry Hinckley between 1946 and 1950, with only 20 hulls produced. Its scarcity and pedigree make it a significant collector's item rather than a mass-market vessel.
- Best for:
- This boat suits collectors and coastal cruisers who value classic craftsmanship and Alberg design principles over modern amenities or high-speed performance.
- Bluewater capability:
- With a heavy displacement of 9050.0 lb, a low capsize ratio of 1.54, and a full/long keel, the boat is inherently stable and suitable for protected coastal cruising, though its age requires careful structural assessment for offshore use.
- Comparables:
- Comparable to other rare 1940s-50s Alberg designs like the Alberg 20 or early O'Day models, though the Hinckley build quality and full keel configuration distinguish it from more utilitarian contemporaries.
