The Baltic 58 was introduced in 1991 to fill the gap between the Baltic 52 and Baltic 64. Like the other Baltic models designed by the firm, the 58 was designed in conjunction with Baltics chief designer, Tor Hinders. Sparkman & Stephens was responsible for the naval architecture and the design of the hull shape, appendages and sail plan. 4 boats have been built to the design.
Heres a design review from Cruising World magazine.
