Abstract
A wave motion isolator for use in suspending a submersible instrument package from a surface buoy by a cable payed out from a pack attached to the instrumentation package. The isolator is comprised of a spring-powered spool which turns on an axle rigidly connected between two bars with guide sheaves attached at each end of the bars. A loop of cable near the buoy is attached to the spring-powered spool and so wound onto the spool that both sides of the loop are payed out simultaneously, thus winding a spiral spring tight around the axle of the spool. One end of the loop passes over a guide sheave at the top of the bars, and the other end passes over a guide sheave at the bottom of the bars.
