Alo 33 Information, Review, Specs

Sailing Performance & Handling

The ALO 33 is defined by its IOR heritage, which dictates a hull form with a significant beam amidships, "pinched" ends, and a pronounced tumblehome. Under sail, these characteristics manifest in a boat that is exceptionally stiff and capable when beating into the wind. The masthead sloop configuration, typical of the mid-70s, relies on large overlapping genoas for its primary drive. In light to moderate air, the 33 is remarkably responsive, benefiting from a high-aspect-ratio fin keel that provides excellent lift and tracking.

However, like many 3/4 tonners of its generation, handling becomes more demanding as the wind increases. The narrow stern and deep, skeg-hung rudder can make the boat "flighty" when sailing deep downwind in a heavy following sea, as the hull's displacement shifts forward. Owners often note that the boat rewards active trimming and early reefing; once the rail is tucked under, the ALO 33 finds its "groove," but over-canvasing can lead to a tendency to round up. Its sea-kindliness is high for its size, with a displacement that provides a sense of security in the choppy conditions of the Skagerrak and North Sea.

Interior Comfort & Variations

For a vessel designed with a racing pedigree, the ALO 33 offers a surprisingly refined interior, largely due to Alf Ortang’s refusal to compromise on cruising amenities. The layout is traditional for a 32-foot cruiser of the era, featuring a forward V-berth, a central salon with a folding mahogany table, and a functional galley to starboard. Because these boats were often delivered as "semi-fabrikat" (owner-finished kits) or fully finished by the yard, the quality of joinery can vary, though the factory-finished models are renowned for their high-quality Norwegian teak and clever use of space.

The boat’s beam provides generous shoulder room in the salon, and the headroom is sufficient for sailors up to six feet. One of the more notable variations involves the navigation station and quarter berth; some hulls were optimized for racing with a more spartan navigation area to save weight, while others feature a deep, comfortable pilot berth for offshore passage-making. Unlike its predecessor, the ALO 28, which focused on maximum occupancy, the ALO 33 prioritizes ergonomics for a crew of four to five.

Known Issues & Buyer’s Checklist

Prospective buyers should approach the ALO 33 with a checklist tailored to 1970s fiberglass construction and IOR design quirks:

• Engine Maintenance: Many original units were fitted with the Bukh DV20 or DV10 diesel engines. While these are famously robust "marine-only" engines, parts are becoming increasingly expensive and difficult to source outside of Northern Europe. Check the motor mounts and exhaust elbow for heavy corrosion.
• Keel-to-Hull Joint: The ALO 33 utilizes an iron fin keel. Inspect the "smile" at the leading edge of the keel-to-hull joint, which may indicate the need for re-bedding or tightening of the keel bolts. Rust weeping from the joint is a common sign that the protective epoxy coating on the iron has failed.
• Deck Core Integrity: Like many Scandinavian boats of this period, the deck may utilize a balsa or PVC foam core for stiffness. Use a plastic hammer to "tap-test" the deck around stanchion bases and the mast step to check for delamination or water ingress, which can be a labor-intensive repair.
• Masthead Rigging: Given the age of these vessels, the standing rigging should be meticulously inspected. The heavy loads placed on the chainplates by the large genoas can lead to stress cracking in the fiberglass reinforcements below decks.

Community & Resources

The primary hub for technical data and owner support is the Alo-klubben (The Alo Club), a Norwegian-based enthusiast group that preserves the history of Alf Ortang’s designs. While the club's activity has shifted toward digital forums in recent years, they remain the definitive source for original sail plans and technical drawings. Information regarding the ALO 33 is also frequently archived within the historical databases of Seilmagasinet, Norway’s leading sailing publication, which has documented the brand's evolution since the 1970s.

The Verdict

The ALO 33 is a "sailor’s sailboat," offering a level of build quality and windward performance rarely found in modern mass-production cruisers. It is an ideal choice for the traditionalist who appreciates the aesthetics of the IOR era and seeks a sturdy, offshore-capable vessel for a modest price.

Pros:

• Exceptional Build Quality: Built to survive the rigors of the Norwegian coast with high-grade GRP and joinery.
• Upwind Performance: Points high and maintains speed in a chop, outperforming many modern wide-stern cruisers.
• Historical Significance: A rare, designer-led model with a distinct racing pedigree.

Cons:

• Downwind Manners: The narrow stern can make the boat restless when running before a heavy sea.
• Maintenance of Iron Keel: Requires diligent monitoring to prevent rust and maintain the hull-to-keel seal.
• Obsolete Engine Parts: Original Bukh or Volvo Penta units may require eventual repowering.
