The Gambling 34 is a Norwegianbuilt cruiserracer conceived by maritime architect Jan Herman Linge in the early seventies and produced by Kristiansands Mek. Verksted, with fewer than 100 examples completed. As an IOR threequarterton design, she sits at the intersection of period handicap rule and family cruising, a 34foot monohull whose modest production run makes her a comparatively rare find today.

Design and Construction

Both hull and deck are solid fibreglass, and the yard offered the boat with different keel alternatives. One is an iron fin keel drawing about 6.10 to 6.40 feet depending on load; the other is a lead fin keel whose loaded draft runs about 5.91 to 6.21 feet different keel alternatives. With a displacement near 10,700 pounds and 4,800 pounds of lead ballast, her ballast-displacement ratio sits at 44.7 percent, and her length-to-beam ratio of 3.34 with a displacement-length ratio of 350 places her among what the data calls heavy cruisers. The wetted surface runs about 301 square feet, and immersion is around 877 pounds per inch.

Rig and Handling

The Gambling 34 was delivered with more than one rig, a masthead rig or a fractional rig different rig options. Under the ISO 8666 reference sail her sail-area-to-displacement ratio is 12.9, rising to 15.1 with a 135 percent genoa, and the relative speed performance index is 46. The theoretical hull speed for a displacement hull of this length is 6.6 knots. Safety-wise, the capsize screening value is 1.80 and the motion comfort ratio is 29.4, figures that frame her as a stable, if not sparkling, offshore candidate rather than a lightweight planing type.

Accommodations

Below, the boat is equipped with eight berths, a galley, and a toilet facility, and the headroom is above average for the class. That berth count and standing room suggest a boat intended for extended crewed cruising rather than minimalist shorthanded passage work, consistent with her heavy-cruiser categorization.

Engine and Propulsion

Several engine alternatives were fitted, and two are quantified in period data. With a Yanmar 7 hp installation and shaft drive, calculated maximum speed is about 2.9 knots; a Volvo Penta 15 hp with shaft drive raises calculated maximum speed to about 4.2 knots shaft-drive transmission. The moderate horsepower and shaft-drive layout speak to a simple, serviceable mechanical package rather than a high-speed motoring profile.

The Verdict

The Gambling 34 is a solid-fibreglass Norwegian cruiser-racer of limited production, offered with sensible keel and rig choices and a roomy eight-berth interior. Her heavy-cruiser numbers and above-average headroom suit comfortable cruising, while the IOR pedigree and multiple rig options give the knowledgeable buyer room to choose a setup. Shallow-draft harbours are off the table given her fin-keel depths.

Pros

  • Solid fibreglass hull and deck from a named Norwegian yard
  • Lead or iron fin keel options with documented drafts
  • Eight berths and above-average headroom for cruising
  • Masthead or fractional rig flexibility
  • Stable heavy-cruiser metrics with capsize screening of 1.80

Cons

  • Iron keel version draws over six feet, limiting marina access
  • Fewer than 100 built, so spares and comparables are scarce
  • Modest calculated motoring speeds with smaller engines
