”Beneteau 323 Estancia ON CA Wiarton Dingy sailing for years, new to yacht sailing”
It is a personal commitment to all things on your boat.
Most boat owners I have met view the lines on their boat as a consumable. The running rigging does take a toll being exposed to the weather 24/7/365. Some will weather better than others. Certainly the Dyneema lines have aged better in my experience.
I do not remove my halyards. I do have a little extra length to them. I keep the tail of the line in a canvas bag on the mast to mitigate some of the exposure and to keep the lines organized.

In the spring I use the extra length with a messenger attached to haul down the line that has been exposed to the weather and give it a good bucket rinse at spring commissioning. My running rigging has been on the boat for 6 years. 2023 season opening I’ll give the lines a careful inspection paying attention to all signs of aging.
