Design and Construction
The 930's hull is made of steel, a choice that anchors the boat's character more than any styling detail. Inside, the interior is like many other boats made of mahogany, giving a conventional warm finish to a fundamentally metal hull. The steel hull carries 3,417 pounds of iron ballast against a displacement of 10,251 pounds, a ballast ratio of 33%, and the boat's length-to-beam ratio of 3.21 places it firmly in the moderate-proportioned cruiser camp rather than the narrow, wiry extremes. The wetted surface area of about 25 square meters (269 square feet) and a fin keel support a shallow-draft profile that lets the boat enter even shallow marinas as the draft is just about 1.38 to 1.48 meters dependent on the load.
Rig and Handling
The Wibo 930 is built with a masthead rig, and the documented sheet specifications are precise: jib and genoa sheets are estimated at 9.3 meters with a 12 mm diameter, the mainsheet at 23.2 meters, and the spinnaker sheet at 20.5 meters, all 12 mm. These are working lengths, not racing oversizes, and they suit a boat whose sail-area/displacement ratio is 14.09 — a modest figure that confirms the 930 as a steady cruiser rather than a light-air flyer. The capsize screening value of 1.75 indicates that this boat could — by that formula alone — be accepted to participate in QUOTE CUT. The immersion rate of about 180 kg/cm (1011 lbs/inch) means loaded waterline changes come predictably, and the 33% ballast ratio keeps the steel hull's mass usefully low in the water.
Accommodations
The boat is equipped with 6 berths, a count that fits the 30-foot envelope without implying sprawling volume. The mahogany interior is described plainly as like many other boats of the period, so the 930's cabin should be read as functional cruising accommodation rather than a distinctive layout achievement. No source details galley, head, or saloon geometry, and the record simply establishes berth count and material as the interior facts on file.
Known Issues
The extracted record contains no documented defect, corrosion path, drainage fault, or structural weakness for the Wibo 930. The steel hull is stated as fact without accompanying caveat, and no owner report or survey quote raises a specific failure mode. Buyers and reviewers should therefore look to ordinary steel-boat vigilance rather than a named, model-specific flaw.
Refits and Ownership
No source describes a refit program, a common upgrade path, or an ownership-cost observation for the 930. The Volvo Penta MD2B diesel of 25 horsepower is the documented single engine, and the masthead rig with its specified sheet lengths defines the running rigging an owner works with. Beyond these fixed points, the available material is silent on what owners have changed or should plan to change.
The Verdict
The Wibo 930 is a steel-hulled van de Stadt cruiser of modest proportions and a shallow, load-dependent draft that widens its range of accessible marinas. Its numbers — 33% ballast ratio, 14.09 SA/D, ，1.75 capsize screening — describe a stable, undramatic coastal boat, while the mahogany interior and six berths supply conventional cruising accommodation. The absence of any documented defect in the record is itself a quiet point in the design's favor, even if it reflects the limits of the extract rather than a clean bill from a survey.
Pros
- Steel hull with iron ballast and a 33% ballast ratio for predictable stability
- Shallow, load-dependent draft of 1.38–1.48 m widens marina access
- Six berths with a conventional mahogany interior
- Masthead rig with documented sheet specifications for straightforward rigging
Cons
- Sail-area/displacement ratio of 14.09 marks it as a modest performer in light air
- No documented refit guidance or ownership-cost data in the record
- Record provides no model-specific known-issue baseline beyond generic steel-boat care
