Bonito 35 Information, Review, Specs

Sailing Performance & Handling

Under sail, the Bonito 35 is widely regarded as a "stiff" and reliable performer, largely due to its high ballast ratio of approximately 40%. With a displacement of roughly 5,500 kg and over 2,200 kg in the keel, the boat handles gusty conditions with significantly less heel than lighter modern cruisers. The hull features a deep fin keel and a spade rudder, which, combined with Pelle Petterson’s focus on hydrodynamic efficiency, allows for exceptional upwind tracking.

The sail area-to-displacement ratio (SA/Disp) sits in the mid-17s, categorizing it as a moderate performance cruiser. Owners frequently report that the boat "comes alive" in 12 to 15 knots of breeze, where its fractional rig allows for fine-tuned control of the mainsail shape. Unlike some broader-sterned IOR designs of the period, the Bonito 35 exhibits predictable behavior when pushed off the wind, avoiding the dramatic broaching tendencies found in more extreme racing hulls. Detailed insights into the design's racing pedigree can be traced back to the designer's own history at Pelle Petterson Design.

Interior Comfort & Variations

The interior of the Bonito 35 reflects the high-water mark of Swedish joinery, typically finished in rich, satin-varnished teak. The layout is traditional for a 35-footer of the era, providing a secure and functional environment for offshore passages. Most configurations feature a V-berth forward with an overhead hatch for ventilation, followed by a full-width head compartment. The main saloon utilizes the boat’s 3.35m beam effectively, offering a central folding table flanked by a U-shaped settee and a straight settee, both of which serve as excellent sea berths.

The galley is usually positioned to the port of the companionway, designed as an "L" shape to provide bracing for the cook while at sea. To starboard, a dedicated forward-facing nav station is a hallmark of its cruiser-racer intent. A significant sibling to this model is the Bonito 32, which follows a similar design language but offers a more condensed living space. Some variations of the Bonito 35 were sold as "owner-finished" kits, leading to slight discrepancies in cabinet work and material choices between hulls, though the structural bulkheads remain consistent across the production run.

Known Issues & Buyer’s Checklist

Prospective buyers of a Bonito 35 should focus their survey on the common technical vulnerabilities of 1970s GRP construction.

1. S-Drive Diaphragm: Most units were originally fitted with Volvo Penta engines and S-drive transmissions. The rubber hull diaphragm has a recommended replacement interval of 7 years; if the maintenance history is unclear, this should be a priority for replacement.
2. Deck Core Integrity: Like many Scandinavian boats of this age, the Bonito 35 uses a balsa-cored deck for weight savings. Areas around stanchion bases and the mast step should be checked with a moisture meter for signs of delamination or water ingress.
3. Fractional Rig Tension: The performance of the boat relies on a straight mast and proper forestay tension. Check the chainplates and the internal glasswork where the shrouds are anchored for signs of stress cracking or "pumping."
4. Rudder Bearing Play: The spade rudder is a high-performance feature but is susceptible to wear in the lower bearings. Check for lateral movement while the boat is hauled out.

Community & Resources

Owners of the Bonito 35 often find camaraderie within broader Scandinavian yachting groups, particularly those dedicated to Pelle Petterson's designs. While there is no longer a dedicated factory website, the Sjöhistoriska Museet (Swedish Maritime Museum) maintains archives on Swedish fiberglass boatbuilders of this era, providing a historical anchor for the brand. Technical support is frequently sourced through the "Maxi" owner associations, as many of the hardware and rigging solutions used by Petterson were standardized across his various design projects.

The Verdict

The Bonito 35 remains a hidden gem for sailors who prioritize build quality and windward performance over the voluminous interiors of modern mass-produced yachts. It is a boat that feels significantly more substantial than its 35 feet would suggest, making it an ideal candidate for coastal racing or spirited North Sea cruising.

Pros:

• Exceptional Swedish build quality and teak interior finish.
• Stiff and stable sailing characteristics with a high ballast-to-displacement ratio.
• Designed by Pelle Petterson, ensuring a pedigree of performance and aesthetics.
• Generally more affordable than better-known brands like Hallberg-Rassy from the same era.

Cons:

• Niche model with limited availability on the second-hand market.
• Aging Volvo Penta S-drive units can be expensive to maintain or replace.
• The narrow-entry bow and traditional hull shape offer less interior volume than modern 35-footers.
