Avance 33 Information, Review, Specs

Sailing Performance & Handling

Under sail, the Avance 33 is frequently described by owners and period testers as a "driver's boat." With a displacement-to-length ratio that sits firmly in the moderate category and a relatively high ballast ratio (often exceeding 40%), the boat exhibits exceptional stiffness. This stability allows it to carry full sail longer than many of its 1980s contemporaries. According to technical archives from the Swedish publication Båtnytt, which historically reviewed Peter Norlin’s designs, the 33 excels in upwind performance, pointing remarkably high thanks to its deep fin keel and well-balanced rudder.

The fractional rig—a 7/8 configuration—gives the helmsperson significant control over mast bend and sail shape, making the boat highly tunable for varying wind strengths. While it lacks the raw downwind speed of modern wide-stern planing hulls, its tracking is superior; it "grooves" into a beat with minimal helm pressure. In light airs, the generous sail area keeps the boat moving, while in heavy weather, the narrow entry helps it pierce through waves rather than slamming, a trait common to Norlin’s "sea-kindly" hull forms.

Interior Comfort & Variations

The interior of the Avance 33 reflects the high-water mark of Finnish carpentry. Eschewing the modular, plastic feel of mass-produced yachts, the 33 is lined with warm, hand-finished mahogany or teak. The layout is a classic "European" arrangement: a functional L-shaped galley to starboard of the companionway and a proper navigation station to port.

The main saloon features two longitudinal settees with a center-line folding table, providing enough seating for six adults. A notable feature for a 33-footer of this era is the headroom, which remains sufficient for sailors up to six feet tall throughout much of the cabin. The forward V-berth serves as the primary owner's cabin, while a large quarter berth tucked behind the navigation station provides excellent sea-berth capabilities or guest accommodation.

In terms of variations, while the hull remained consistent, some units were fitted with a "tall mast" option for competitive club racing. Additionally, later hulls produced toward the end of the 1980s featured minor interior refinements, such as updated head compartments and improved overhead liners. Unlike many of its siblings, the Avance 33 did not have a widely produced Deck House (DH) variant, as the builder focused on maintaining the low profile and aesthetic purity of the Norlin design.

Known Issues & Buyer’s Checklist

Prospective buyers of an Avance 33 should focus their inspection on the specific structural and mechanical areas common to Finnish builds of this vintage:

• Keel-to-Hull Joint: Like many Norlin designs with deep fin keels, the "keel smile" (a hairline crack at the leading edge of the joint) can appear if the boat has experienced a grounding. It is vital to inspect the internal glass-reinforced plastic (GRP) grid—the "floor timbers"—for any signs of cracking or separation from the hull.
• Deck Core Integrity: Avance used a sandwich construction for the decks to save weight. Over forty years, hardware bedding (stanchions, cleats, winches) may have leaked. Use a moisture meter or perform a percussion test to check for delamination or soft spots in the balsa or foam core.
• Engine & Saildrive: Most Avance 33s were originally equipped with Volvo Penta MD7 or 2000-series engines. Buyers should pay close attention to the saildrive diaphragm seal; if it is more than seven years old, it requires replacement. Furthermore, the internal cooling passages of these older engines are prone to salt-water scale buildup.
• Rigging Fatigue: Because the 33 utilizes a fractional rig with significant tension on the backstay to control mast bend, the chainplates and the mast step should be inspected for stress fractures or "pitting" in the stainless steel components.

Community & Resources

Owners of Avance yachts are primarily concentrated in Northern Europe, where the brand maintains a cult following. The most significant resource for technical data and historical context is the Finnish "Avance Purjehtijat" (Avance Sailors) community. While they do not maintain a high-traffic English website, their technical archives are often cited in regional sailing forums like CruisersForum and SailNet when discussing Scandinavian build quality. For technical drawings and original design specifications, the Peter Norlin design archives, often preserved by Swedish maritime heritage groups, remain the authoritative source for restoration projects.

The Verdict

The Avance 33 is a "sailor’s sailboat," offering a level of craftsmanship and aesthetic grace that is increasingly rare in the sub-35-foot market. It is an ideal vessel for a couple or a small family looking for a seaworthy coastal cruiser that can still hold its own in a local regatta.

Pros:

• Exceptional Build Quality: Finnish craftsmanship that rivals much more expensive marques.
• Elegant Design: Peter Norlin’s lines remain timeless and command respect in any marina.
• Point & Flow: Superior upwind performance and a balanced, rewarding helm.
• Interior Warmth: Extensive use of real wood creates a cozy, high-end living environment.

Cons:

• Narrow Beam: The traditional hull shape offers less interior volume and "open plan" feel than modern yachts.
• Aging Systems: Original engines and electrical panels likely require significant investment if not already updated.
• Accessibility: Most well-maintained examples are located in Scandinavia, making parts and specific model knowledge harder to find in North America.
