In the calculation of the vibration of the marine propeller shafting, it should be needed to assume the additive mass of water at the propeller and take into the consideration the damping effect. There are not so much reliable data for the above, at present. The authors have carried out the experiment of the hydrofoil in the translatory oscillation and applied its results to the actual calculations. This 1st reports shows the measuring apparatus and analytical methods of the experiment. The hydrofoils applied to the experiment are as follows. (1) Two-dimensional models of the aerofoil section and the circular arc section. (2) Three-dimensional models of the elliptic outline forms which axis length ratio are 0.25,0.5 and 1.0. Then, the fluid dynamic characteristics of the hydrofoil are showed in the non-dimensional forms. That is, [numerical formula]In the above formula each notation has the meaning that, [table]
