Iona 32 Information, Review, Specs

Sailing Performance & Handling

The Iona 32’s performance characteristics are defined by its heritage as a mid-century coastal cruiser. With a displacement of approximately 7,800 lbs and a Sail Area/Displacement (SA/Disp) ratio of roughly 15.6, the boat is generally considered slightly under-canvased by modern standards. This results in a vessel that feels stable and predictable in a breeze but may require a large genoa to remain competitive in light air. Its motion comfort ratio of 20.6 reflects a hull that is relatively "stiff," providing a secure feel for family cruising.

Under sail, the masthead rig offers a balanced helm, though the fin keel and skeg-hung rudder configuration provide more maneuverability than directional tracking compared to the full-keel designs of the previous decade. Owner anecdotes from the era suggest the boat performs best on a reach, where its 25.2-foot waterline can be fully utilized. However, its capsize screening formula of approximately 2.02 indicates that while it is an excellent coastal and "island-hopping" vessel, it lacks the ultimate righting capability required for extreme offshore racing.

Interior Comfort & Variations

Because many Iona 32s were sold as "hull and deck" kits, the interior arrangements can vary significantly between individual hulls. However, the standard factory-influenced layout typically follows the successful formula of the Islander 32: a V-berth forward, followed by a head and hanging locker, a central saloon with a dinette, and a galley located near the companionway for optimal ventilation.

The use of "tumblehome" in the hull design—where the beam narrows toward the deck—adds a distinctive aesthetic but requires careful placement of interior cabinetry to maximize the 10-foot maximum beam. Most versions feature an abundance of dark wood joinery, characteristic of the 1970s aesthetic, though some "owner-finished" boats utilize lighter teaks or even painted bulkheads to brighten the cabin. Headroom is adequate for a 32-footer of this era, usually hovering around 6 feet in the main saloon, making it a viable weekend cruiser for four adults.

Known Issues & Buyer’s Checklist

Prospective buyers should approach the Iona 32 with a focus on its construction era and "kit boat" potential.

• Deck Core Integrity: Like many GRP boats from the early 1970s, the Iona 32 utilized plywood or balsa coring in the decks. Inspection for "soft spots" or delamination around the chainplates and stanchion bases is critical.
• Kit-Finish Quality: Because many were finished by amateur builders, the quality of the electrical wiring, plumbing, and bulkheads-to-hull tabling can vary wildly. A professional survey of the structural bonding is highly recommended.
• Keel Bolts and Joint: The fin keel is a bolted-on lead or iron casting. Inspect the "smile" at the leading edge of the keel-to-hull joint for signs of movement or oxidant weeping, which may indicate the need for re-torquing or bolt replacement.
• Rudder Post and Skeg: The skeg-hung rudder is a sturdy design, but the bushings can wear over time, leading to "play" in the steering. Check for moisture ingress in the rudder blade itself.

Community & Resources

The most significant technical resource for Iona 32 owners is the broader community associated with Joseph McGlasson designs. While there is no dedicated Iona 32 Class Association, technical support and historical data are frequently shared through the Islander Yachts Association, as the two models share nearly identical hull geometries and rigging specifications.

The Verdict

Pros:

• Classic Aesthetic: Features the timeless lines and "tumblehome" hull characteristic of 1970s West Coast designs.
• Solid Construction: Thick fiberglass laminates common in early GRP production provide a sturdy feel.
• Affordability: Offers a 32-foot cruising platform at a lower entry price than more famous production brands.

Cons:

• Variable Finish: Amateur-finished interiors require deep inspection of systems and joinery.
• Light Air Performance: Can feel sluggish in winds under 8 knots without a significant headsail.
• Obscurity: Harder to find specific replacement parts or historical documentation compared to high-volume manufacturers.
