Irwin 43-CC Mk II Information, Review, Specs

The Irwin 43-CC Mk II began production in 1985, representing an updated version of a popular model within the Irwin Yachts lineup. Ted Irwin, the visionary founder of Irwin Yachts, initiated his boat-building career at a young age, officially establishing Irwin Yacht and Marine Corporation in 1966. Throughout its operational history, which concluded in 1992, Irwin Yachts maintained its position as one of the largest sailboat producers in the United States, predominantly utilizing fiberglass construction.

Irwin's design philosophy was notably diverse, encompassing both successful racing boats and comfortable, practical vessels tailored for the burgeoning Caribbean yacht charter market. The Irwin 43-CC Mk II benefits from this dual focus, designed to be both a capable performer and a comfortable cruiser. While the Mk II was introduced in 1985, the model line continued to evolve, with the Irwin 43-CC Mk III appearing by 1990. The Mk III often featured a wing keel and a slightly different reported sail area compared to its predecessor.

Sailing Performance and Handling

The Irwin 43-CC Mk II, with a length overall of 45.5 feet and a waterline length of 35.5 feet, is characterized by its moderate displacement and cutter rig. Her Sail Area to Displacement (SA/D) ratio of approximately 18.65 suggests a vessel capable of performing adequately in lighter air, while also possessing sufficient sail-carrying ability for cruising conditions. With a Displacement to Length (D/L) ratio of about 260, the Irwin 43-CC Mk II falls into the moderate-to-heavy displacement category, indicative of a solid and seakindly cruiser rather than a light-displacement racer.

The ballast to displacement ratio, at around 30.7%, suggests a level of stability suitable for cruising. Equipped with a fin keel and a skeg-hung rudder, the boat is generally described by owners as sailing and motoring beautifully. The cutter rig is particularly well-suited for offshore sailing, as it breaks down the total sail area into smaller, more manageable sails, easing handling in various wind conditions. Her hull speed is calculated at 7.98 knots.

Accommodations and Layout

The Irwin 43-CC Mk II is highly regarded for its spacious and livable interior, making it a popular choice for liveaboards and long-distance cruisers. The center cockpit design allows for a generous aft cabin, which typically features a centerline queen bed. The interior layout also commonly includes a large main living area, a well-appointed galley, and two heads. The substantial water capacity of 180 gallons and fuel capacity of 105 gallons further support extended periods at sea. While specific headroom figures vary, the overall design prioritizes comfort and ample living space below deck.

Owner's Perspectives

Owners of the Irwin 43-CC Mk II consistently praise its suitability as a comfortable and practical long-distance cruiser. Many have found the vessel to be an ideal platform for extended family voyages or retirement cruising. The original 56-hp Perkins 4-154 Series 200 diesel engine, commonly installed in these models, has a reputation for being problem-free over thousands of hours when properly maintained. The boat's great layout and ability to sail and motor beautifully are frequently highlighted by those who own them.

However, some common maintenance considerations have been noted by owners. A recurring issue often cited is related to the fuel tanks, which were typically installed under the cabin sole and can pose challenges for access or replacement when maintenance is required. While debates exist regarding its ultimate "bluewater" capability, many owners successfully undertake significant long-distance cruises, attesting to the boat's inherent robustness and liveability.
