They sure can be repurposed. Seabags will likely take it (you'll have to check with them), and give you a free bag for it. They need the raw materials.So not to hijack the topic.... sorta related.... what do you do will sas past their usefull life?
My sails are at their end per the sailmaker i had inspect them. They are 14 yrs ... so its time.
Can anything usefull be made out of the old sails. Or do you just toss them?
I had some emotional attachment to my last mainsail , from the memories it provided. These bags are the strongest material and with a design and build that will last several lifetimes.
