The Tes 28 Magnam represents the pinnacle of Tomasz Siwik’s design philosophy, blending the trailerable versatility of Polish lake cruisers with the robust seaworthiness required for offshore passages. Launched in 2010 as a successor to the popular Tes 678 and 720 models, the 28 Magnam was engineered to maximize internal volume without sacrificing the "fast cruising" DNA that Tes Yacht has cultivated since 1980. Built by the Jacht Plast shipyard in Okuniew, Poland, the vessel is distinctive for its high freeboard, elegant hull lines, and a plumb bow that extends the waterline to improve hull speed. While many 28-footers are confined to coastal jaunts, the Magnam is frequently CE-rated for Category B (Offshore), a testament to its structural integrity and stability.
