Oceaan 25 Buyer's Guide
The Oceaan 25 is a 24.84-foot fractional-sloop cruiser designed by Ericus Gerhardus van de Stadt and built by K & S Polyboats from 1977. For a shopper scanning the used market, she is a small, light-displacement coastal boat with an iron-ballasted fin keel and skeg-hung rudder, whose documented personality is mostly about hull numbers and rig dimensions rather than factory-fitted luxuries.
Layouts on the Used Market
Buyers should expect to evaluate each individual boat on its own merits rather than against a standard published plan. The constant facts are the hull shell and rig: 21.3-foot waterline, 9.25-foot beam, 4,800-pound displacement, and a load-dependent draft of 4.92 to 5.22 feet. Any interior you find refitted or original is a variable the survey must capture.
Equipment and Common Upgrades
Jib and genoa sheets run 24.8 feet at 3/8 inch, a mainsheet at 62.1 feet and 3/8 inch, and a spinnaker sheet at 54.6 feet and 3/8 inch. A buyer should treat running rigging replacement as a baseline expectation rather than an upgrade, and judge any fitted sail-handling or navigation gear on the specific boat.
What to Inspect
The immersion rate is about 800 pounds per inch and the wetted-surface area is 226 square feet, since load-dependent draft means a heavily equipped boat will sit deeper than the 4.92-foot minimum draft varies with load from 4.92 to 5.22 feet. Confirm the actual floating draft against the advertised condition and watch for added tankage or ballast that shifts her trim.
Availability and Buyer's Takeaway
No regional market data was supplied for this model. For the buyer, the practical checklist is short:
- Verify the draft under load before assuming marina access.
- Inspect the solid fiberglass hull and deck for repair history.
- Treat all sheet rigging as due for renewal unless freshly replaced.
- Obtain a survey that captures the interior layout.
