Difference Between Working Load Limit and Break Strength for Boat Straps

Published 10/24/2016

Question:

I have a 7,500 lb boat on a tri-axle trailer. I need to secure the boat with transom and bow tie-downs. How does the Safe Working Load or maximum load relate to the weight of the boat?

The working load limit is the safe working load limit for the strap. The max break strength instead is how much weight it will hold right before it breaks. Basically WLL is 1/3 the max break strength.

The part # IMF14393 has a 1,500 lb max break strength and a 500 WLL.
