A large stocked anchor is used for the stow net fishery. Since one side fluke of this anchor directs upward on the sea floor, It is reasonable to get rid of this unnecessary and obstructive fluke. The absolutely-roll-stable single fluke anchor (ARS anchor) which is able to orient and penetrate on the sea floor irrespective of drop attitude was tentatively manufactured. We took applicable results in some degree resulting from the investigation of characteristics pertinent to the primary function of anchor. ARS anchor takes right stand and operates normal function at 10L of the dragging distance from the upset state, the coefficient of holding power is 10 at about 15L. The stability of ARS anchor is normal state, its veering capability also shows good result compared with the ordinary anchor. But its holding power is inferior to some extent to the ordinary anchor.
