* Quick splice method available which reduces the break strength but also reduces the splice complexity to 1
** NA in Dielectric leakage indicates that the product is not recommended for use in dielctric situations due to the ropes potential moisture gain
***Absorbed or entrained moisture or impurities will increase a ropes conductivity dramatically
**** Oceanographers energy absorption is at a WL of 30%

For computing weight in sea water: (Wt. in Air) - (Wt. in Air)(1.03) / (Specific Gravity of Rope)

Components of Elongation

* Hysteresis refers to a recoverable portion of stretch over a period of time after a load is released.
