Data from tests of model hydrofoils is analyzed to determine the experimental hydrodynamic characteristics. The method of analysis is discussed and comparison is made between theory and experiment for single foil configurations. Agreement is good except in the critical speed region where the effect of shallow water is different from that indicated by the theory. Analysis of tandem foil tests is also made, and good agreement is found between test results and theory. The effect of tank depth is discussed and some observations on wave patterns are given. Recommendations for future testing are made. Author
