Guide for Checking 71-inch Turtle Excluder Device Opening
This one page guide (PDF) for checking a 71-inch Turtle Excluder Device (TED) opening contains guidance for measurements and includes diagrams.
This one page guide (PDF) for checking a 71-inch TED opening contains guidance for measurements and includes diagrams.
Step 1: Measure the distance from the TED frame forward along the side of the escape hole cut to the leading edge of the escape hole cut A to B. This measurement must be greater than or equal to 26-inches when stretched.
Step 2: Measure the distance from the posterior edge of the TED frame to the trailing edge of the flap C to D. This measurement must be taken from the center of the frame and must not exceed 24-inches as the TED is hanging (not stretched).
Step 3: Measure the distance the flap is attached beyond the posterior edge of the TED frame E to F. This measurement must be taken from the center of the frame and must not exceed 6-inches when the TED is hanging.
Step 4: Measure the leading edge of the escape hole cut G to H. This measurement must be greater than or equal to 71-inches when stretched. Note: This measurement must also be obtained with flap attached.
Step 5: Measure the escape opening (inside the flap) I to J. This measurement must be greater than or equal to 71-inches when stretched. Take this measurement in a horizontal straight line at the aft edge of the exit hole.
Accelerator Funnels
If an optional accelerator funnel is used, the funnel must have a minimum straight-line stretched measurement as follows:
All offshore waters and the inshore waters of Georgia or South Carolina = 71”.
All inshore waters except GA & SC = 44”.
