The Coastline is a midrange rated 5.5/5/-1/2. A turn rating of -1 with a fade rating of 2 suggests a gliding flight with a little right drift at speed and a moderate left finish for a right-hand backhand. Its ratings suggest it is less suited to players seeking long turnover lines. Swiftflyte, an in-house brand of the Canadian distributor BY Group, sells it as the midrange in a three-disc set with the Wayfinder and Ground Control, and its box calls it a beefy, wind-fighting midrange with distance and a dependable finish. The PDGA approved it on 10 November 2025 (25-168). TryDiscs does not yet record a plastic row for it as of September 2026.
