The Navy is procuring the Spectra-based ropes for new ships and to replace existing lines on vessels from Whitehill Manufacturing Corp., based in Chester, Pa. Whitehill recently developed the new rope using Spectra fiber to further improve the strength, durability and safety of the lines. Spectra fiber is, hydrophobic-meaning it will not absorb moisture or deteriorate in water.
In the past, injuries caused by breaking or recoiling ropes were of critical concern to the Navy. The new rope is a custom-designed four-strand rope produced by Whitehill. This rope was engineered with one strand slightly shorter than the others, causing it to break first when the rope was about to fail, dissipating energy and alerting sailors to clear the premises.
