Twin keel fins Model: SW (Swallow) [Features of Keel Fins] Wide overall for stability. ★SW (Swallow) The fin shape is like a swallow's wings, with the top of the fin extending backward and flexing smoothly. This length towards the back also prevents unintentional fin-outs during top actions. It makes it easier to turn the board during ripping, so try hitting it hard. Also, slits are appropriately placed at the base of the fin, dispersing water flow and designed for flexible movement. Suitable for small waves and powerless conditions. If you have keel fins and feel they are heavy, please try these. A very easy-to-ride, friendly twin fin design. Anyone can ride it without feeling any discomfort. Recommended for surfers who want to draw smooth lines unique to twins! 〈Wave Size Compatibility〉 Small waves (knee to chest) ●●●●● Medium waves (chest to shoulder) ●●●●○ Large waves (head to double overhead) ●●○○○ 〈Performance Evaluation〉 Action ●●●●● Drive ●●●○○ Speed ●●●●○ Brand new, unused.
