Learn which weak inserts are approved for use under the 2021 Atlantic Large Whale Take Reduction Plan modifications and how to install weak inserts.
Requirements for the use of buoy line with a maximum breaking strength of 1,700 lbs through the use of manufactured weak rope or weak inserts (below) went into effect May 1, 2022 under the 2021 modifications to the Atlantic Large Whale Take Reduction Plan. These requirements apply to the Northeast Lobster/Jonah crab trap/pot fishery only. Requirements for all other areas, other trap/pot fisheries, and gillnet fisheries remain the same.
The modifications remove the requirement for weak link at buoys and other surface system flotation devices, though they are not prohibited, and adds requirements for weak rope or insertions within the buoy line.
Fishermen are also encouraged to maintain their buoy lines to be as knot-free as possible. Splices are considered to be less of an entanglement threat and are thus preferable to knots.
Average breaking strengths were determined through 10 consecutive tests on a calibrated rope-breaking machine at the NEFSC lab in 2021. To be approved, the average breaking strength must be within 10 percent of 1,700 lbs. These tests are the basis for NOAA Fisheries approval of this rope.
Knots cannot be used to attach weak rope or inline links as inserts in three-strand rope.
Below are images of approved weak inserts, as well as videos on how to install approved weak inserts. Many of these are available at Ketcham Supply.
All weak rope (1,700-pound breaking strength) inserts must be at least 3 feet in length, must be connected with a tuck (at least 3 recommended), splice, or a sleeve, and must be a contrasting color.
All in-line manufactured weak links must be stamped with the breaking strength, must be a contrasting color, and must be connected to the regular-strength rope with a tuck (at least 3 recommended) or splice.
Please check this page for updates, as we will be adding weak inserts as they are approved.

Watch a demonstration on how to use inline links with half-inch rope.
Note: Only one link may be used at each insertion.
The small in-line manufactured weak links are now approved for use with 1/2-inch rope as an alternative to weak rope. In-line links must be placed every 60 feet in the top 75 percent of one endline. The bottom 25 percent of the endline does not require weak links. LMA 3 vessels may use any of the approved links below.
All in-line manufactured weak links must be stamped with the breaking strength, must be a contrasting color, and must be connected to the regular-strength rope with a tuck (at least 3 recommended) or splice.
We recommend hauling from the strong end. If you must haul from the weak end, we recommend leaving extra space between the sled and the first trap.
Seaside Rope inline links for 5/8" line have been approved for use, installed with spices or tucks.
Manufactured by Coastline Cordage Group, this braided 7/16 inch breakaway link breaks at an average of 1,612 lbs and is 69 inches long. The link breaks at the stitching, therefore any attachment method must not reinforce the stitching (see example of double Becket below, which is not allowed). Originally approved May 18, 2022, new version approved April 2023. Recommend installation with at least 3 splices or tucks. Available at Ketcham Supply in New Bedford, Massachusetts.

Note: DO NOT attach with a double or single Becket
