Tes 678 BT Buyer's Guide
Shopping the used Tes 678 BT means looking at a small, Polish-designed coastal cruiser built from 2008 by Tes Sailboats, with a pivoting swing keel that makes her as happy on a shallow lake as on a sheltered seaboard. She is a 24-foot fractional-sloop whose appeal lies in beachability and relative interior room rather than offshore pedigree, so a buyer's eye should stay on condition and the realities of a light, lightly ballasted hull.
Layouts on the Used Market
Charter four-cabin layouts are the more common on the used market, but both are available, and ex-charter examples are common. Either way the boat's hull is noted as more spacious than 54 percent of similar designs, so even the tighter configuration stays usable for weekend coastal hops. The swing keel that lifts to about one foot drawn is the defining layout feature — it lets a buyer consider moorings and ramps a bigger boat could not use.
Equipment and Common Upgrades
On the used market the 678 BT commonly carries a practical offshore-and-inland toolkit: solar, autopilot, chartplotter, heating, bow thruster, and AIS are all commonly fitted. For a buyer, that cluster means a boat set up for extended shoulder-season cruising without shore power anxiety and with close-quarters control from the bow thruster. The chartplotter and AIS together cover navigation and traffic awareness, while heating extends the season aboard.
What to Inspect
The review places the 678 BT's capsize screening value at 2.24, a score that means she would not be cleared for ocean racing, so inspect her as a coastal boat whose limits should be respected rather than stretched. Her ballast ratio of 23 percent is higher than only 4 percent of similar designs, and with 770 pounds of iron on 3,300 pounds displacement the keel pivot and lifting hardware deserve close look for wear or corrosion. The swing keel trunk and pivot bolt are the structural heart of the beaching concept and should be checked for water ingress or elongation.
Availability and Buyer's Takeaway
These boats are typically found in the Netherlands, Canada, Switzerland, Poland, and Germany. For a buyer, the takeaway is a light, roomy trailerable cruiser best judged as a sheltered-water boat:
- Confirm keel pivot and trunk condition before purchase
- Verify commonly fitted systems (solar, autopilot, heating, bow thruster) work as described
- Treat her as a coastal/inland cruiser, not an offshore candidate
- Prefer ex-charter only after checking layout wear from frequent use
