The OI 41 was also among the earliest production cruisers to trade sailing performance openly for maximum accommodation space. During a 20-year production run ending in 1991, about 1,100 boats were launched in several three-digit variants. More than 1,000 are still sailing worldwide.
Design and Production History
Introduced in 1972, the Out Island 41 represented a deliberate shift toward volume and comfort rather than speed. Its center-cockpit layout fitted three cabins—forward, amidships, and aft—into a hull 41.25 feet long, with a 34-foot waterline, a beamy 13.82-foot breadth, and a shoal 4.17-foot draft over a full shoal keel.
Early versions had a designed displacement of 24,000 lbs and carried 683 sq ft of sail. By 1981, Morgan literature listed a more realistic cruising displacement of 27,000 lbs and a higher-aspect, 775-sq-ft rig. The 416, introduced that year, carried a much larger sailplan still.
Before the Classic, the model progressed through the 413, the 414 from 1973–76, and the 415 from 1977–80, with mostly minor interior changes, followed by the 416. Catalina Yachts acquired Morgan Yachts in 1984. For the 1986 Out Island 41 Classic, the hull was fundamentally reshaped: a deeper long fin keel and skeg-hung rudder replaced the full shoal keel and attached rudder, while the deck and interior retained much the same general appearance. The Classic models sail much better than their predecessors while preserving the same accommodation footprint and topside character. The revised hull retained the same general deck and interior appearance.
Construction and Structure
Structurally, the OI 41 is a very sound boat with a solid fiberglass laminate hull. The bulkheads and all furniture are securely tabbed to the hull, while transverse deck beams prevent the deck from lifting under rig loads.
The bulkheads are bonded to a molded deck liner rather than directly to the plywood-cored deck. On some boats, they show twisting or cracking where they meet the liner.
On early boats, the hull-to-deck joint sat below the fat cove stripe beneath the sheer, where it was vulnerable to docks and Travelift slings. In 1975, the joint was moved to deck level, where it belongs.
Rig, Steering, and Handling
A ketch rig was standard from the beginning, and a sloop alternative appeared in 1977. Period testers found that the full-keel OI could hold about 45 degrees off the wind in flat water without excessive leeway. In rough water, however, she slides off at an alarming rate. Once waves build, motorsailing to windward becomes the norm.
The boat is happier on a good reach. She tracks well with the wind on or near the beam and balances easily enough on that point of sail to leave the helm unattended. Off the wind, she performs well enough if a spinnaker is flown.
Many boats have hydraulic steering, which reinforces the impression of poor sailing performance. Early 413 and 414 models used cable steering. Owners report that the key to making an OI 41 go is an inner forestay carrying the largest sail the triangle will hold.
Accommodations
The OI 41’s expansive interior is built around a large, separate owner’s stateroom aft, generous shared space amidships, and a forward guest stateroom. The original 1972 arrangement had no below-deck passage to the aft cabin; a walk-through was added in 1974.
Forward-cabin layouts vary. Some boats have V-berths, while others use over-and-under singles. Saloons may have dinette tables or fold-down bulkhead tables. Some have settees running the full length of the cabin, while others substitute a pair of captain’s chairs on one side.
In theory, the boat can sleep seven. In practice, she works best as a family cruiser or as a spacious home for a couple, with a spare cabin for guests. Older finish quality looks dated and rough, while Classic interiors seem fresher.
Machinery, Tanks, and Known Issues
The engine compartment remained beneath the center cockpit throughout production. Most boats used Perkins diesels: early examples had the 4-108 or Westerbeke 4-107, later boats used the 4-154, and the Classic used Yanmar.
Beyond the bulkhead-to-liner cracking already noted, the mainmast step over the keel deserves attention. It is iron and can corrode the aluminum mast heel when the insulation between them fails.
The polyethylene tanks are also prone to failure. Because they were installed before the deck went on, replacing them with comparably sized units is nearly impossible without major structural renovation. The usual solution is to fit smaller tanks that can pass through the companionway.
Refits and Ownership
Earl Hinz’s 1973 ketch Horizon, hull 95, illustrates the sort of changes owners have made over the years. Hinz added a door between the aft stateroom and engine room to provide internal forward access. He also increased fuel capacity to 180 gallons and water capacity to 175 gallons.
The Verdict
The Out Island 41 Ketch is a hugely successful, comfortably voluminous coastal cruiser. Its charter-bred practicality still rewards owners who accept its sailing limitations. The Classic’s revised keel and rudder address the worst handling shortcomings while retaining the roomy three-cabin layout.
Pros
- Exceptionally spacious, three-cabin center-cockpit layout
- Walk-through access to the aft cabin from 1974 onward
- Solid laminate hull, with securely tabbed bulkheads and furniture
- Hull-to-deck joint moved to deck level in 1975
- Large production base, parts familiarity, and an active fleet of more than 1,000 boats
- Classic variant sails materially better with its fin keel and skeg-hung rudder
Cons
- Poor full-keel windward performance in waves; motorsailing is often required
- Bulkhead-to-liner cracking and iron mast-step corrosion occur on some boats
- Polyethylene tanks are prone to failure and cannot be replaced at their original size without major work
- Older interiors look dated
- Hydraulic steering is common and reinforces a poor-sailing impression
