An analytical model is presented for the transverse vibration of a semi-infinite beam due to forced longitudinal harmonic motion at the end. The model is applied to the 'snaking' behavior of a floating hose-string attached to an SPM buoy: the surge response of the buoy to incident sea waves results in the hose-string bending in the plane of the water surface. The dependence of the snaking characteristics - frequency, amplitude, and wavelength - on the buoy's surge frequency and amplitude and on the damping present is established. Predictions from the model are compared with model test measurements of snaking.
