ANCHOR 



Two, 1 , 200-pound headache balls and a Stimson anchor served to anchor the lift line 

 (clump) while the recovery gear was being positioned. This anchor was left on the bottom 

 between Lift Attempts No. 1 and No. 2 to hold the line and toggle in the vicinity of ALVIN. 

 The anchor was recovered during the lift. 



SALVAGE PONTOONS 



Standard B.F. Goodrich inflatable rubber pontoons rated at 8.4-ton buoyancy lift were 

 used. After MIZAR had lowered the lift line and toggle into the water, a pontoon was used 

 to suspend the bitter end of the line thus permitting the line to be cast off from the ship. 

 Casting the line free from the ship eliminated the effects on the line of MIZAR's motions and 

 maneuvering. This pontoon supported the lift line while the task force was in Woods Hole 

 for repairs, and was also used to support ALVIN during the tow to shallow water. 



Two additional pontoons were attached for safety. These pontoons became deflated 

 during tow, presumably from chafing, and were replaced by an additional pontoon. Two 

 more pontoons were made ready on deck in case they were required. 



SALVAGE NET 



A 30-foot by 30-foot net of nylon webbing was used. The net was buoyed by lengths of 

 polypropylene pipe, and contained a nylon line to permit the net to be gathered. When AL- 

 VIN was near the surface, this net was wrapped around her and gathered to help secure her 

 for the tow to shallow water and prevent loss of any equipment.
