What is the major disadvantage of using manila rope?

The major disadvantage of using manila rope is that it is easily damaged by sunlight. Manila rope, made from natural fibers derived from the abaca plant, lacks the UV resistance that many synthetic ropes possess. Prolonged exposure to sunlight can weaken the fibers, leading to deterioration and a decrease in strength. This is crucial for an operator to consider, as using a rope that degrades rapidly in sunlight can jeopardize safety on a party boat.

Other factors, while they may be considerations, do not outweigh the impact of UV degradation. For instance, synthetic ropes are typically lighter and can have better resistance to mildew, making them more suitable for marine environments. Additionally, manila rope can handle significant loads, but its vulnerability to sunlight diminishes its reliability over time, making it less desirable in outdoor, sun-exposed situations.
