The first two anchors were quickly installed in 59 feet (18 m) of water, penetrating 9 and 14 feet ( and m), respectively. This deep penetration indicated a rather soft coral or a layered media (coral/coral sand) at these two sites. The third anchor was installed in 112 feet (34 m) of water; this anchor was to be used as the starboard bow anchor. The fluke penetrated a short distance and was badly damaged. The initial assumption was that the fluke was unstable during penetration, and this caused the piston to separate from the fluke prematurely. However, a subsequent firing with a CEL 20K anchor at roughly the same location indicated that this coral was extremely hard. Since divers reported shallow penetration of the 10K anchor, the work boat proof-loaded the anchor to determine its status. The work boat easily pulled the anchor out. The front of the fluke was bent back, and the fluke could offer no holding capacity in the coral rubble produced during this penetration. The fourth 10K anchor was assembled and transported to the same site. This anchor was rapidly lowered to the seafloor and fired in almost a prone position. The rapid (almost free-fall) lowering caused the anchor to plane out. The fluke grazed the seafloor at a very shallow angle and landed on the surface a short distance away. The 10K with the 2 x 2-foot (61 x 61-cm) fluke will have to be lowered at a more reasonable rate, perhaps less than 400 fpm (120 mpm) to prevent kiting; this rate will be determined at a later Figure 10.
