Stronger than Amsteel, Amsteel Blue is a high-performance 12-strand single braid of 100% Dyneema® fiber. It is now available in a variety of colors.
AmSteel-Blue yields the maximum in strength-to-weight ratio, very low stretch, and is stronger than the same sized wire rope constructions — yet it floats.
It’s the highest strength single braid Samson makes.
The Samthane coating enhances an already high abrasion and cut resistance.
Adding a cover is recommended for areas handled by winch or rope clutches.
Good for high load, static applications like halyards, wire replacement, and lightweight spinnaker sheets.

Heavy on the technical side...
