Tape-Drive Carbon Polyester is made up of a grid of carbon fiber tapes bonded to a sail made with polyester laminates. This material combination is an option for boats under 45-feet as a more economical choice than sails made with Spectra laminates. Shown below are two common polyester laminate options: Dimenison Polyant’s PM05T (the T stands for single sided taffeta), PM10T (for bigger boats because it has a denser weave of polyester yarns). While the polyester yarns have more stretch than Spectra yarns, smaller boats don’t generate the high loads that bigger boats do. Sailors have to balance performance vs. the price.
Tape-Drive Carbon Polyester sails are not all black, which makes them look more traditional.
