Abstract (en)

The proposed technology relates to a hull arrangement (12) for a watercraft (10) for preventing biological growth or biofouling. The arrangement comprises: a hull (14) having an inside and an outside; an electrically conductive first film (18) covering the outside of the hull (14) on a first portion of the hull (14); a first electrical connector (20) connecting to the conductive first film (18); a second electrical connector (22) connecting to the conductive first film (18) and spaced apart from the first electrical connector (20); and an electric power source (24) connected to the first electrical connector (20) and the second electrical connector (22) and configured for supplying a first electric current via the first electrical connector (20) and the second electrical connector (22). The first film (18) constitutes an uninterrupted electrical conductor between the first electrical connector (20) and the second electrical conductor (22).
