Morgan 452 Ketch
Description
The Morgan 452 Ketch, designed by Henry Scheel and first built by Morgan Yachts in1978 with limited production (around 20-30 units), heavy-displacement center-cockpit formula for coastal and Bahamas-style cruising through its shallow fin keel with skeg-hung rudder and masthead ketch rig (shoal draft 4.75 ft standard; deeper options to 5.5 ft), emphasizing stability and ease for short-handed East Coast or island-hopping sailors who prioritize volume over velocity. Measuring 45 feet LOA with a 13.5-foot beam, 39.25-foot LWL, and 30,000-pound displacement (including 8,300 pounds of lead ballast), it deploys 734 square feet of sail area, yielding a conservative sail area/displacement ratio of 12.21 for deliberate performance—PHRF around 180-200, hull speed of 8.4 knots, and plush comfort ratio of 35.35 with a capsize screening of 1.74—that delivers a sea-kindly, low-motion ride on reaches and runs in 15-25 knots but lags upwind (50 degrees apparent) due to its displacement/length of 221, demanding motor-sailing in light air or headwinds and early reefing to mitigate weather helm, while the divided ketch sail plan aids balance and single-handing without a massive main.
