ABSTRACT : The holding ability of four types of anchors was examined in relation to the resistance against the towing rope set at various angles. Experiments were performed using four type anchors (VDR-type, VDH-type, VDS-type and VDQ-type). These anchors were pulled using the Research Vessel, HOKUTO (19T). The tension force was measured using a loadcell connected to the towing rope. The experimental results indicated that the VDS-type anchor showed the highest resistance, the VDR-type anchor showed the most stable resistance, and the DVQ-type anchor showed the lowest resistance.
