Designed to be in compliance with the Federal Whalesafe Gear regulations, our BreakAway Esterpro™ has been developed to assist affected fisheries to maintain their current setups with as little interruption as possible. Designed in a 5/8" offering, BreakAway Esterpro™ has a designed low break strength of 1700lb to make it easier for entangled whales to free themselves and reduce the risk of serious injury.
