According to varying accounts, the HANS CHRISTIAN 36, MARINER POLARIS, UNION 36, MAO TA 36, and EO 36 are all nearly the same and built by the same yard in Taiwan. (at the time called Union Ship Co.)
They are all based on a lengthened version of the HANS CHRISTIAN 34, the boat Bob Perry was originally commissioned to design (though few were built under this name).
