The Wibo 990 is a 32foot6inch steelhulled sloop designed by Dutch naval architect Ericus Gerhardus van de Stadt. Jachtwerf G. van Wijk & Zoon put the boat into production in 1984. With a fin keel, spade rudder, and fractional rig, she sits at the practical end of the cruising spectrum. She was built to be owned and sailed, not simply admired from the dock.

Design and Construction

The 990’s proportions reflect Van de Stadt’s mid-eighties work. At 32.5 feet overall, with a 26.5-foot waterline and 11 feet of beam, she has a length-to-beam ratio of 2.97, making her beamy for her length. Her displacement is nearly 11,700 pounds, including a 4,343-pound iron ballast keel. A displacement-length ratio of 280 places her firmly among loaded cruising boats rather than lithe racers.

Steel is the defining material choice: both the hull and deck are steel, and the hull laminate is solid rather than cored. Wetted surface is roughly 344 square feet. An immersion rate of about 1,288 pounds per inch means she sits heavily and changes trim slowly under load. Her capsize screening value of 1.97 suggests a stability profile acceptable under that single formula for offshore consideration.

Rig, Handling, and Machinery

The Wibo 990 has a fractional sloop rig carrying 575 square feet of sail. Her sail-area-to-displacement ratio is 17.87—modest, favoring control and ease over outright acceleration in a breeze.

The specified sheet dimensions are practical and consistent. Jib and genoa sheets are 33.1 feet long and half an inch in diameter. The mainsheet is 82.8 feet long at the same diameter, while the spinnaker sheet measures 72.9 feet.

A single 20-horsepower Bukh diesel drives the boat through a shaft transmission. Hull speed is near 6.9 knots. Draft varies with load from about 5.22 to 5.52 feet, keeping her within the draft limits of most marinas while still giving the fin keel enough bite to stand up to the sail plan.

Accommodations

Below, the Wibo 990 has six berths, reflecting her family-cruising intent rather than solo minimalism. Her 11-foot beam gives the accommodation real width amidships.

No source provides further details of the interior layout. In a 32-footer of this displacement, however, the six-berth count implies a saloon that converts to sleeping space, along with forward and aft quarters typical of the type.

Verdict

The Wibo 990 is a straightforward steel cruiser from a respected Dutch design lineage, intended for owners who value substance over sparkle. Her weight, beam, and modest sail plan make her stable and forgiving in ordinary cruising, while steel construction promises longevity if properly maintained. She won’t win around the buoys, but she was never meant to.

Pros

  • Steel hull and deck, with a solid, non-cored hull laminate, for durability
  • Beamy proportions provide six berths and livable volume
  • Load-tolerant draft keeps her within the limits of most marinas
  • Van de Stadt design with a sensible capsize screening value

Cons

  • Heavy displacement and low SA/D limit light-air performance
  • Steel demands vigilant corrosion maintenance, which is absent from the record
  • Sparse documented detail about the interior arrangement and access to systems
