Alden 30
Description
The Alden 30 typically refers to classic designs by renowned American naval architect John G. Alden (1884–1962), known for his elegant, seaworthy wooden yachts emphasizing grace, performance, and offshore capability. There isn't a single mass-produced "Alden 30" model like some fiberglass boats, but several ~30 ft designs exist, including the Alden 30' Keel/Centerboard Sloop (a wholesome auxiliary cruiser from WoodenBoat plans) and examples like the 1922 Gaff Sloop (model #141, e.g., Welwyn, built by George Lawley & Sons). These are traditional wooden boats—often carvel-planked over steamed frames—with classic lines: spoon bows, counter sterns, gaff or Marconi rigs, and shoal draft options via centerboard for versatility in coastal or gunkholing waters. They're prized for timeless beauty, solid build, and balanced sailing characteristics, though maintenance on wood is a factor.
