Abstract : A series of wake survey experiments were conducted on Model 5365 representing the R/V ATHENA in the DTNSRDC towing tank. Longitudinal, tangential, and radial velocity components for experiments at model speeds of 2.87 knots (1.48 m/s), 5.22 knots (2.68 m/s), 6.96 knots (3.58 m/s), and 13.5 knots (6.94 m/s) are presented. Several comparisons are made between wake surveys with different water depths, trims, and speeds. A comparison of full-scale and model-scale towing tank wake survey measurements is also presented. Harmonic analyses of the circumferential distribution of the velocity component ratios. Wake survey Shallow Water R/V Athena Model 5365.
