Design and Construction
The Oceaan 25's hull is solid fiberglass with a solid fiberglass deck, and the builder is K & S Polyboats. The length-to-beam ratio comes in at 2.68, a narrow-ish figure for a 24.84-foot overall length that speaks to a hull with relatively little beam for its length rather than a beamy daysailer. The wetted surface of the underwater body is about 226 square feet, and the immersion rate is about 800 pounds per inch, so she sits at a measured 4.92 to 5.22 feet of draft depending on load and can still tuck into most marinas enters most marinas at that draft. The capsize-screening ratio is 2.19 and the comfort ratio 17.13, figures consistent with a light-displacement coastal design rather than an offshore passagemaker.
Rig and Handling
The boat is rigged as a fractional sloop. Jib and genoa sheets are 24.8 feet long and 3/8 inch in diameter, the mainsheet runs 62.1 feet at the same 3/8 inch, and the spinnaker sheet is 54.6 feet long, also 3/8 inch sheet lengths and diameters as specified. Those numbers describe a modest rig where control lines are short and manageable, suited to a crew handling her without powered winches. The skeg-hung rudder and fin keel combination, paired with the 21.3-foot waterline, gives a hull-speed calculation of 6.18 knots.
The Verdict
The Oceaan 25 is a van de Stadt–designed small cruiser built by K & S Polyboats from 1977, with a clear and quantifiable hull personality: narrow beam for her length, modest wetted surface, and a load-dependent draft that keeps her marina-accessible. The known rig data is precise and useful.
Pros
- Designed by Ericus Gerhardus van de Stadt, a recognized Dutch naval architect.
- Solid fiberglass hull and deck construction.
- Draft of 4.92–5.22 feet keeps her into most marinas.
- Well-documented sheet dimensions for a fractional-sloop rig.
Cons
- Light comfort ratio (17.13) limits her to coastal use.
