Luders 37 (Cruisemaster 37, Cheoy Lee 37)
Description
The Luders 37 is a classic sailboat design, most commonly referring to the Cruisemaster 37 (also known as the Cheoy Lee Cruisemaster 37 or Luders 37 in some archival records). It was designed by renowned American naval architect Alfred E. "Bill" Luders Jr. (of Luders Marine Construction) and built by Cheoy Lee Shipyard (Hong Kong) starting in 1969, with limited production (exact numbers low, in the dozens). It's a traditional, full-keel (long keel) fiberglass monohull cruiser emphasizing seaworthiness, a dry ride, and solid construction—often praised for its forgiving motion in a seaway, offshore capability, and quality build (thick fiberglass, teak accents). The design is conservative with moderate performance (hull speed ~6–7 knots), good stability, and a practical interior (typically 4–6 berths with V-forward, saloon settees, galley, enclosed head, headroom ~6'). It's a niche classic for coastal/offshore cruising or liveaboard use, though not a light-air flyer.
