J. N. R. has been building 6 new Tsugaru-maru type train ferries which ply between Aomori and Hakodate. In the launching of these ferries, the bending stresses and the deflections of hulls are measured dynamically. At the same time, draft distributions, vertical acceralations, water pressures at the bottom of hulls and the distance of travels, which are necessary to calculate the hull bending moment at the moment of lift by the stern more accurately are also measured dynamically. The means to measure dynamical deflection of large ship has been developed by the author for the first time. Those means of measurements and the cautions which must be taken in using those measn are described.
