A net for use as an embarkation-debarkation net having spacer blocks provided integrally therewith for maintaining the plane of the net configuration spaced forwardly of a rear portion of the respective distributed spacer blocks. Securing elements are provided at less than all of the crossing positions of the longitudinal and transverse lines of the net. An improved spreader structure is provided utilizing a tubular cross member and short tubular vertical members for receiving the longitudinal lines of the net. The spacer blocks provide a self-fending action when the net is used as an embarkation-debarkation net, and provide cushioning of cargo where the net is used as a cargo net.
