Method for installing an anchor that is released in the sea, especially for installation of in soft seabed sediments. An anchor is rebased in free fall from an at rest position or nearly at rest position and with the longitudinal axis vertical from a position in the water, and that ensures directional stability and nonroutional acceleration during movement towards the seabed. The anchor body (14) has a main member or shank (22) with a regular cross section, especially circular or regular polygon form, with tip (23) and with upward projecting shank (25) with lower average density than the main anchor body has. The anchor body is shaped such that the center-of-gravity lies lower than the middle of the total anchor length and below the average distance to the sum of all the fluid forces which ensures directional stability and nonrotational acceleration during free fall and penetration into the seabed sediments.
