Nylon Ropes

Nylon is the strongest synthetic fiber.
It does not absorb moisture.
It holds knots and splices well.
It has a good appearance.
The ends can be sealed by melting with a hot knife to prevent fraying (though seizing is still recommended).
High energy absorption capacity (elasticity).
Excellent resistance to repeated loading (stretching and returning).
Excellent abrasion and friction resistance.

Longer lifespan due to high abrasion resistance.
Lubricated filaments protect internal fibers from abrasion caused by leg friction when the rope stretches.
A protective shield forms on the surface fibers during abrasion.
High flexibility ensures high resistance to abrasion and friction.
Nylon absorbs 20% of its weight in water but remains flexible and easy to handle.
Good resistance to sunlight degradation; only nylon ropes with a diameter less than 1 inch require special care.

Very suitable for towing due to its elasticity (25% to 33% elongation).
2. 5 to 4.5 times more elastic than natural fibers (whose elasticity comes only from the twisting process).
Also suitable for mooring lines (espia).
Retains 85% to 95% of its strength when wet.

Conflicting information: Maurílio initially suggests nylon floats (weighing 11% of its weight in air), but Hensen from Tangelsing Port says it does not.
The provided table indicates nylon does not float; its specific weight is 1.14 compared to saltwater's 1.026.
Easier to handle because a thinner nylon rope can replace a thicker natural fiber rope for the same breaking strength.
