Design and Construction
Van de Stadt's mid-eighties hand shows in the 990's proportions. The length-to-beam ratio of 2.97 makes her beamy for her length, and the displacement-length ratio of 280 places her firmly in the loaded cruising category rather than the lithe racer camp. Steel is the defining material choice: both hull and deck are steel, with solid (non-cored) hull laminate, while the ballast is iron. At 32.5 feet overall with a 26.5-foot waterline, she carries a wetted surface of roughly 344 square feet, and her immersion rate of about 1,288 pounds per inch means she sits heavily and changes trim slowly under load. The capsize screening value of 1.97 anchor suggests a stability profile acceptable under that single formula for offshore consideration.
Rig and Handling
The 990 is built with a fractional sloop rig carrying 575 square feet of sail area, yielding a sail-area-to-displacement ratio of 17.87 — modest, favoring control and ease over outright acceleration in breeze. The guiding sheet dimensions are practical and uniform: jib and genoa sheets run 33.1 feet at half-inch diameter, the mainsheet is 82.8 feet of the same diameter, and the spinnaker sheet 72.9 feet. The shaft-drive transmission behind a single 20-horsepower Bukh diesel moves the boat at a hull speed near 6.9 knots. Draft varies with load between about 5.22 and 5.52 feet, which keeps her within the draft limits of most marinas anchor while still giving the fin keel enough bite to stand up to her sail plan.
Accommodations
Below, the 990 is equipped with six berths, a count that speaks to her family-cruising intent rather than solo minimalism. The beam of 11 feet gives the accommodation some real width amidships. No source details the interior layout beyond berth count, but the six-berth arrangement in a 32-footer of this displacement implies a saloon convertible to sleeping space plus forward and aft quarters typical of the type.
The Verdict
The Wibo 990 is a straightforward steel cruiser from a respected Dutch design lineage, built for owners who value substance over sparkle. Her weight, beam, and modest sail plan make her a stable and forgiving boat in ordinary cruising, while the steel construction promises longevity if maintained. She will not win around the buoys, but she was never meant to.
Pros
- Steel hull and deck with solid laminate for durability
- Beam-forward proportions give six berths and livable volume
- Load-tolerant draft keeps her in most marinas
- Van de Stadt design with sensible capsize screening value
Cons
- Heavy displacement and low SA/D limit light-air performance
- Steel demands vigilant corrosion maintenance absent from the record
- Sparse documented detail on interior arrangement and systems access
