MAXIMUM HOLDING POWER OF ANCHORS

The maximum holding power of an anchor depends on the structure of the sea-bed but few data are available on the anchorage. full scale trials on three types of anchor were carried out in the sand bed off Matsuho-no-Ura, Hyogo Prefecture. Newly designed absolutely-roll-stable single fluke anchors <ARS-S Anchors: 6, 3, 1 ton> proved to be very effective and developed a holding power of approximately 6 times the weight of the anchor. The maximum holding power ratio of stockless bower anchor <Hall's Anchor: 5.6 ton> was about 3.5. It should be noted that Hall's Anchor turned over in all trials. It was observed that the fluke often failed to penetrate the sea bed. Stocked Anchor <5.2 ton> was stable but had a poor maximum holding power ratio of about 3.6.
