    Harbor Master, Jyväskylä Yacht Club (Jyväskylän Veneseura ry)

    “In June 2022, we carried out an inspection of mooring buoys and chains at the Juurikkasaari harbor of Jyväskylä Yacht Club. Unwa Oy performed the work with great professionalism and speed, and the inspection report was very detailed with photos and explanations. Later in the autumn, the necessary repairs were carried out, also by Unwa Oy, with the same high level of professionalism.”
