Expansion of hull form Development using Shinpachi
１．Corresponds to the development of merchant ships and high speed boats
We will support the hull form development of various vessel types, making full use of the maximum flow velocity 2.6m/s.
２．Automatic measurement
We control the water channel in a short time automatically, and we are measuring effciently.
