Batten pocket anti-chafe tape for the Hobie 18 mainsail. Your sail is expensive! Save it from an early grave with space age tape that affords ultimate protection to the batten pockets—where the shrouds eat through the cloth. Even covered shrouds don’t postpone this for long! This remarkable material has up to 10 times the abrasion resistance of steel and yet this transparent tape will not hide your sail’s colors or leave you with a gummy, unsightly residue that Duct tape and other tapes will. Great for use on all full-battened sails!
