Description
Laboratory experiments to provide a better understanding of the
dynamics of drifting life rafts were conducted in an outdoor, above ground
wave tank which measures 48 feet 10 inches in length, 23 feet 7 inches in
width and has a depth of 24 inches. Vessel models were subjected to fan
generated wind and waves created by a hinged wave paddle and their
leeway was recorded and analyzed. The models were found to move so that
wind and wave forces remained balanced. The life raft drag coefficients
found are of the same order of magnitude as those ascertained in the
numerical modelling of the same experiments.
