1972 Irwin Mark 4

Built when Irwin was really hitting its stride, this Mark 4 has the kind of solid fiberglass hull and straightforward systems that make refits approachable and worthwhile. The classic sheerline and wide side decks give you secure footing moving forward, while the cockpit is deep and protected enough for longer passages or lazy afternoons on the hook. The two-cabin layout gives real privacy for guests or family, and the generous beam translates to a surprisingly roomy salon for a 70s-era cruiser. With plenty of locker space and tankage, this hull was designed with actual cruising in mind, not just weekends. For a sailor who enjoys tinkering and bringing a capable classic back to her best, this is a very rewarding platform.

An Irwin Mark 4 is a smart match for waters where you may mix relaxed coastal daysailing with occasional longer hops offshore. The moderate draft lets you explore shallower anchorages without sacrificing tracking and upwind ability when the breeze is up. Her displacement hull and balanced sail plan deliver a comfortable, predictable motion in the afternoon chop common in this region. The roomy cockpit and generous shade options suit warm-weather cruising, while the two-head layout is a real plus when you have guests aboard for extended weekends. Combined with simple, accessible systems typical of this era, it’s a boat that’s easy to understand, service, and enjoy in local conditions.
