Aquaglide’s press-fit fins give any kayak with a US fin box, such as the Chelan and Blackfoot, improved portability and ease of use – no more fiddling with the tab and screw attachment system. Press-fit fins use friction for a secure, tool-free attachment on any US fin box, and feature removable stoppers that allow for adjustment to varying fin box tolerances. Glass Flex Construction means they are lightweight, rigid, and durable. Our proven fin template means excellent tracking and weed-shedding performance. Choose between two different graphic treatments inspired by Chelan and Blackfoot Angler kayaks.
