Flag line for yachts
A flag line takes more punishment than most sailors expect. It spins constantly in the wind, bakes in UV light all season and runs through tight sheaves inside spreaders and mast tops. A cheap line yellows, goes brittle and snaps within a season. A quality braided polyester flag line stays white, stays flexible and keeps your flag flying year after year.
Premiumropes supplies braided polyester flag line in small diameters, cut to any length you need. Low stretch keeps the flag taut and prevents it from wrapping around the stay. The white braid stays white, even after a full season in the sun. Order online and get the right line delivered fast.

Flag lines are one of those small jobs that quickly become a big frustration when something goes wrong. Here is what to look for and how to replace a flag line without losing it inside the mast.
Material matters
Most cheap flag lines are made from nylon or low-grade polyester. Nylon absorbs water, loses strength when wet and yellows quickly in UV light. Within one season it becomes stiff and brittle. Braided polyester, sometimes called Dacron, is the right material for a flag line. It resists UV, holds its colour, stays flexible and has low stretch so the flag stays taut in the breeze.
Diameter and weight
A flag line needs to be thin and light. Too much weight in the line pulls the flag down and makes it harder for the flag to fly freely. A small diameter also runs more smoothly through the sheave at the masthead or spreader tip.
Replacing a flag line: use the old line as a messenger
Before you remove the old flag line, always tie the new one to the end of it. Pull the old line through slowly and let it guide the new one into place. Losing a flag line inside a spreader or mast is one of the most avoidable jobs on a yacht. A few seconds of preparation saves a frustrating afternoon with a wire and a lot of patience.
