The Tes 678 BT represents a pivotal moment in the evolution of the Polish "Mazurian" style of pocket cruisers. Designed by Tomasz Siwik, the "BT" suffix stands for "Back To," signifying a return to the classic lines of the original Tes 678—one of the shipyard's most successful models—but updated with modern laminating techniques and refined interior ergonomics. This vessel is designed specifically for the cruising sailor who requires trailerability without sacrificing the creature comforts usually reserved for 30-foot yachts. Its design philosophy centers on a high-volume hull with a significant beam and high freeboard, allowing it to navigate shallow inland waters with its swing-keel configuration while providing a stable platform for coastal hops.
