FFG Model - Dynamic PMM Test

NAHL's 380 FT Towing Tank features a planar motion mechanism (PMM). Dynamic PMM testing allows for the derivation of corresponding ship hydrodynamic/maneuvering coefficients.
This experiment was performed for undergraduate students in USNA's EN455 (Seakeeping & Maneuvering) course as a weekly laboratory exercise. The yellow model represents a scaled frigate (FFG) hull-form
