I think people should keep in mind as well that synthetic winch line is what those in the sailing world call dyneema line. The line often spends a lot of it's life exposed to the elements and sun and can last a long time under extremely high tension forces. Food for thought.After being told a synthetic rope would only last a year I did a little research and found that, if cared for and kept out of sunlight, synthetic rope and tow straps (etc.) should last 10 years or more. Average winch rope life was 3-5 years if covered except in use and kept clean.

Interesting thought. A friend with a small sea cat mentioned that to me but I have no experience in sailing. His comment was that he thought sailing lines used different, or specially-treated, materials that made them last longer. I have in the past purchased lines treated with UV protection but I do not know if that is true of a winching line. And I mean that literally, I do not know. Are they the same? Hard to believe the winch market itself supports the entire industry so it makes sense the lines have other applications.I think people should keep in mind as well that synthetic winch line is what those in the sailing world call dyneema line.

My understanding is that dyneema sailing line is the same as winch line. do keep in mind that many boats have line bags in the cockpit that the excess line is stored in, that's done to prevent it getting tangled, people tripping on it, but also give it a little protection from the elements, but the line that gets used the most is exposed on deck and in the rigging the whole time. I don't know anyone who sails full time that replaces their sailing line yearly unless they are racing.Interesting thought.

I was shocked when told to anticipate that my synthetic winch line would need replacing yearly; I had not seen that anywhere. The saleslady who told me that said it was the manufacturer's recommendation, but also said hers lasted 3+ years with normal use (number of pulls through the year), which is likely more use than mine will see. I suspect it is a combination of being overly cautious to prevent lawsuits and desire to generate more sales.
In the much more cautious climbing world, any nylon rope older than 10 years should be retired, regardless of how it was used or stored. Will it automatically fail at 10 years? Probably not. Is your life worth more than a $200 replacement? Hopefully…
Some of it is just the consequences of what happens if it fails though. A failed recovery rope might dent your car, and in extreme cases cause bodily harm or death. A failed climbing rope is extremely likely to cause harm or death. When in doubt, replace it.
OK, thanks, good to know. I recall going out a few times and we always did a quick line inspection (among other things), but thinking back in 5-10 years I only recall helping restring a line once, and that was because it got caught in a pully and torn/scuffed a little and he replaced it out of caution.My understanding is that dyneema sailing line is the same as winch line. do keep in mind that many boats have line bags in the cockpit that the excess line is stored in, that's done to prevent it getting tangled, people tripping on it, but also give it a little protection from the elements, but the line that gets used the most is exposed on deck and in the rigging the whole time.

I should also add that "number of pulls" in regards to winch line is interesting to consider when sailing lines when in use are under a lot of continuous and varying pressure, along with being pulled in and out constantly and for days/months/years on end.
I'm guessing you are right and that the winch line people are being legally cautious and trying to sell more line.
