- Option 1: All buoys must be attached to the buoy line with a weak link having a breaking strength no greater than 600 pounds (272.4 kg). Weak links may include swivels, plastic weak links, rope of the appropriate breaking strength, hog rings, rope stapled to a buoy stick, or devices approved in writing by the NOAA Fisheries Assistant Administrator (See contact information in Chapter 75.01(A)(3)). In addition, the weak link must be designed so that the bitter end of the buoy line is clean and free of knots when the weak link breaks; or
- Option 2: All buoy lines must be made entirely of sinking and/or neutrally buoyant line; or
- Option 3: All groundlines must be made entirely of sinking and/or neutrally buoyant line.
State Waters Outside the Exemption Line AND in Federal Waters – Lobster & all other trap/pot gear

In addition, the weak link must be designed so that the bitter end of the buoy line is clean and free of knots when the weak link breaks plus each weak link must be installed as close to the buoy, floatation and/or weighted device as possible. Weak links must be designed in such a way that the bitter end of the buoy line is clean and free of any knots when the weak link breaks. Effective April 5, 2008
