Mariner 48 Ketch (Mayflower 48)
Description
The Mariner 48 Ketch (also sold as the Mayflower 48 or Stadel 48) is a heavy-displacement bluewater cruiser designed by George Stadel III (son of noted designer George Stadel Jr.) and built in fiberglass by May Flower Yachts in Taiwan starting in 1979, with a limited production run (exact hull count not documented, but very low due to the niche market and era). It features a strong, teak-decked hull with a fin keel and skeg-hung rudder for balanced handling and protection, a powerful masthead ketch rig for versatile short-handed sail handling in heavy weather, and a spacious, comfortable interior suited for extended offshore cruising or liveaboard use—prized for its seaworthiness, dry ride, and proven capability in rough conditions (many examples have logged significant ocean miles).
