(b) Retrieving of gear, —- (i) After firing the charge, After the 
charge had been fired the paravane rig was separated into four sections at 
the point formerly occupied by the charge. The stern section drifted off 
with the tide, the starboard and port sections swung far ovt due to the 
action of the paravanes, while the forward quarter remained directly astern 
of the vessel, The starboard paravane and gauge block were first taken 
aboard since two piezoelectric gauges were attached, The port paravane and 
gauge block were taken aboard, and then the main towline, the forward gauge 
block, and associated piezoelectric gauges. The same principles held dur- 
ing this procedure as were described in Sec. 16(bi). The stern portion of 
the gear was then retrieved as previously described, 
(ii) After a misfire. Due to the complexity of the rig, retrieving a 
charge after a misfire was very difficult. However, this was usually accom 
plished by allowing the starboard paravane and gauge block to drop back be= 
side the stern part of the gear and by pulling the port paravane and gauge 
block ahead beside the forward part of the gear. This brought all com- 
ponents into one line and they were then brought aboard in a fashion similar 
to that described for the one dimensional rig, At times when the gear be- 
came badly tangled, due to mishandling of the paravanes, it was necessary 
to retrieve without attempting to fire. Under these circumstances it was 
not always possible to retrieve this gear in an orderly fashion, and it was 
brought up in the safest manner feasible,
