About the Morgan Out Island 415 Sailboat

Designed by Charles Morgan and built from 1975 to 1981, this substantial cruising sailboat represents the classic American approach to offshore sailing. With 300 hulls produced during its six-year production run, the Out Island 415 established itself as a serious bluewater cruiser for sailors seeking traditional sailing characteristics and robust construction. The boat's long keel configuration and conservative design ratios reflect Morgan's commitment to seaworthiness over speed. At 41 feet overall with a 27,000-pound displacement, this is a heavy, stable platform that prioritizes comfort and safety in challenging conditions. The impressive comfort ratio of 34.97 indicates exceptional motion comfort at sea, while the conservative capsize screening formula of 1.85 demonstrates excellent stability characteristics for offshore passages. Morgan's fiberglass construction was well-regarded during this era, and the masthead sloop rig provides straightforward sail handling. The generous beam of nearly 14 feet creates spacious accommodations below, making extended cruising comfortable for couples or small families. While not built for speed, with a hull speed of 7.81 knots, the Out Island 415 offers the dependable, predictable sailing qualities that made Morgan yachts popular among serious cruising sailors of the late 1970s.

Known Issues View all 9 issues →
High
The deck-to-hull joint on Morgan Out Island series boats uses an outward-turned flange that is vulnerable to separation and water intrusion, particularly at the bow and stern quarters. This joint was often secured with screws and sealant rather than a robust structural bond, and failures here can allow significant water into the laminate.
High
Balsa core decking was used extensively throughout the OI 415, and any fastener penetrations that lost their sealant over the decades are common water entry points. Widespread soft or delaminated deck sections are a frequent finding on survey, particularly around winch bases, stanchion bases, and deck hardware.
High
The full-length keel on the OI 415 uses encapsulated ballast, and the external keel-to-hull joint is prone to cracking and weeping, allowing water intrusion into the ballast cavity over time. This can lead to internal rust staining and structural softening in the keel-hull bond area.
