When comparing boat ratchet straps, read the working load limit (WLL), not only the breaking strength.
FMCSA’s cargo-securement rule, 49 CFR 393.106(d), sets the combined WLL of tie-downs at no less than half the secured cargo’s weight in applicable commercial transport. Treat that as a regulatory baseline, not a complete boat-loading plan.
A strap marked with a high break strength may still have a much lower WLL. Compare strap width, length, stitching, hooks, and ratchet feel. Wider webbing can spread pressure, but it must fit the boat’s contact points without bunching.
Check that hooks seat fully on trailer anchors and that metal parts show no rust or distortion. Small details matter. A strap that binds or slips during a test pull deserves a closer look. UV exposure, salt spray, and sharp hull edges can weaken webbing; edge protectors help, but do not repair damaged straps.
Inspect stitching for pulled threads and webbing for cuts, glazing, or stiffness. I would not choose by rating alone: anchor placement and hull shape change how loads behave, and that judgment is easy to get wrong. FMCSA’s figures describe cargo securement, not a guarantee against boat movement on every road.
