Rethana 25 Buyer's Guide
Shopping the used Rethana 25 means looking at a 24.93-foot German fiberglass day-sailer built by Rethana Yachts from 1979, with a centerboard hull and a masthead sloop rig. She is a light, stiff boat meant for day use rather than overnight stays, and the brokerage examples you meet will reflect that brief.
Layouts on the Used Market
The Rethana 25 carries no cabins, berths, or heads in her specification, and her headroom and water capacity are zero. Expect an open day-boat interior rather than an enclosed cruising layout best suited as a day-boat. A buyer viewing a specific hull should treat any enclosed berth or head as a later owner modification, since the original design recorded none.
Equipment and Common Upgrades
On the used market a bimini, teak decks, and autopilot are commonly fitted to these boats. Teak decks are a cosmetic and grip upgrade that a buyer should inspect for softening, while an autopilot and bimini speak to day-sailing comfort rather than any structural change. The single engine in the specification shows zero horsepower and zero fuel capacity, so verify what propulsion — if any — is actually installed aboard a specific hull.
What to Inspect
Confirm the centerboard trunk and pivot for free movement and absence of leakage, and check the solid fiberglass hull for osmosis or impact damage. The listed zero-horsepower engine and zero fuel capacity mean you must physically verify any drivetrain present and its fuel arrangement rather than trust the spec sheet. At a viewing, lower and raise the board by hand to feel for binding in the trunk.
Availability and Buyer's Takeaway
These boats typically appear in Germany and the Netherlands. Before committing, walk the hull for glass condition, work the centerboard, confirm the engine and fuel setup, and review any teak deck for bond failure.
- Inspect centerboard trunk for leaks
- Verify engine and fuel capacity installed
- Check teak decks for softening
- Confirm open day-boat layout matches specification
