Catalina 320 Mk II Information, Review, Specs

Sailing Performance & Handling

The Catalina 320 Mk II is engineered primarily as a coastal cruiser, prioritizing stability and ease of handling over raw racing speed. With a Sail Area/Displacement (SA/Disp) ratio hovering around 17.5, it is remarkably capable in light-to-moderate air, a characteristic often noted in editorial assessments such as those by Cruising World. The hull features a relatively flat bottom and a fine entry, which helps it plane slightly in heavy air downwind, though its primary strength is its predictable motion in a seaway.

The boat was offered with two keel configurations: a deep fin keel for better upwind tracking and a wing keel for sailors in "thin water" regions like the Chesapeake or Florida. While the wing keel slightly reduces lift when beating to weather, it maintains a low center of gravity that preserves the boat's stiff sailing characteristics. The Mk II’s helm is notably responsive due to its large elliptical rudder, and the T-shaped cockpit allows the helmsman easy access to the primary winches, making it a favorite for couples or single-handed sailors.

Interior Comfort & Variations

The hallmark of the 320 Mk II is an interior that maximizes every inch of its 11' 9" beam. The Mk II updates focused on higher-end finishes and improved functionality; where the original 320 used lighter ash or oak, the Mk II transitioned to more traditional teak joinery and upgraded upholstery. The layout remains centered around a large U-shaped galley to port—featuring a front-loading refrigerator and a propane stove—which is unusually spacious for a 32-footer.

Accommodation is divided into a V-berth forward and a massive athwartships double berth aft, tucked under the cockpit sole. The aft cabin is a standout feature, offering significantly more headroom and ventilation than many of its contemporaries. One of the most critical refinements in the Mk II was the updated electrical panel and the inclusion of more robust lighting fixtures. Unlike its larger sibling, the Catalina 34, the 320 Mk II focuses on a more open-concept salon that trades a dedicated navigation station for more expansive seating.

Popular Mentions & Media

While the 320 Mk II does not have a single "famous" circumnavigating owner, its cultural footprint is defined by its ubiquity in North American sailing schools and club racing fleets. It is frequently cited as the "gold standard" for the first-time cruiser. The model’s longevity and the high volume of hulls produced (over 1,000 across the original and Mk II production runs) have made it a recurring subject of technical analysis in Mainsheet Magazine, the official publication of the Catalina owners' community.

Known Issues & Buyer’s Checklist

Prospective buyers should approach the Catalina 320 Mk II with a focus on a few model-specific maintenance areas common to the Douglas-era designs:

• The "Catalina Smile": Though less prevalent on the Mk II than on older 1980s models, buyers should still inspect the leading edge of the keel-to-hull joint for cracking, which can indicate the need for re-torquing keel bolts or fairing.
• Chainplate Sealing: The stainless steel chainplates pass through the deck and require periodic re-bedding. Neglect here can lead to moisture ingress into the plywood bulkhead, a costly repair.
• Engine Exhaust Riser: Most Mk II units are powered by Yanmar diesel engines. The mixing elbow (exhaust riser) is a known wear item that can clog with carbon or corrode internally, leading to engine overheating.
• Rudder Post Bearing: Check for excessive "play" or vibration in the steering system. The bushings in the rudder port can wear over time, especially if the boat has been kept in high-current areas.

Community & Resources

The primary hub for technical support is the Catalina 320 International Association, which maintains an exhaustive technical wiki and a registry of hull numbers. This association is one of the most active in the sailing world, providing members with detailed "how-to" guides for everything from replacing the traveler to upgrading the freshwater system.

The Verdict

The Catalina 320 Mk II is arguably one of the best-balanced boats in the manufacturer’s history, offering a sophisticated blend of volume, safety, and resale value.

Pros:

• Exceptional interior volume for a 32-foot hull.
• Large, ergonomic T-shaped cockpit with stern rail seats.
• Strong secondary market demand and parts availability.
• Predictable, stiff handling that builds confidence for novice cruisers.

Cons:

• Limited storage for long-term blue water provisioning (best suited for coastal hops).
• The wide beam can lead to a "slamming" motion in short, steep head seas.
• The large aft berth can be difficult to access for those with limited mobility.
