Design and Construction
The Morgan 42-1 is built around a 42-foot overall length with an 11.5-foot beam and a 30.5-foot waterline, giving it a length-to-beam ratio of 3.65 that reads as a moderately narrow, seakindly hull form anchor. Its displacement-length ratio of 299 places it firmly among heavy cruisers, and at 19,000 pounds displacement with lead ballast it carries the mass that category implies. The wetted surface of the bottom is about 387 square feet, and the boat settles into its loaded lines at an immersion rate near 1,224 pounds per inch. The theoretical hull speed works out to 7.4 knots, the figure expected for a displacement hull of this waterline.
Rig and Handling
The boat carries a masthead sloop rig, and the period sail plan data spells out the standing and running gear in unusual detail. Halyards for the main, jib, and spinnaker each run 113 feet and are sized at 1/2 inch diameter, while sheets for jib and genoa measure 42 feet at 0.55 inch, and the mainsheet is a 105-foot, 0.55-inch line anchor. With the ISO 8666 reference sail the sail-area-to-displacement ratio is 17.7; hoist a 135% genoa and that climbs to 20.9, a meaningful jump in light-air drive for a heavy hull. The fin keel draws between 5.51 and 5.81 feet depending on load, shallow enough to make most marina entrances accessible. On the safety side, the capsize screening value is 1.73 and the Motion Comfort Ratio is 33.1, figures consistent with a stable offshore-capable cruiser rather than a twitchy racer.
Accommodations
The 42-foot hull on a 30.5-foot waterline with an 11.5-foot beam and 19,000-pound displacement implies volume consistent with the heavy-cruiser classification.
Known Issues
The Morgan 42-1 shows no pattern of structural defects, systemic rig failures, or recurring construction faults unique to the model across its service history.
The Verdict
The Morgan 42-1 is a Charles Morgan-designed late-1960s heavy cruiser built by Morgan Yachts in solid fiberglass with a fin keel and masthead rig. Its numbers describe a stable, load-carrying offshore sloop with accessible draft and a comfort-oriented motion profile.
Pros
- Heavy-cruiser displacement-length ratio of 299 with lead ballast
- Capsize screening of 1.73 and Motion Comfort Ratio of 33.1
- Load-dependent draft of 5.51–5.81 ft suits most marinas
- 135% genoa lifts SA/D to 20.9 for better light-air performance
Cons
- No published accommodation plan or defect history for the model
- Heavy displacement limits outright speed under 7.4 kn hull speed
