## Long description

Waydoo Subnado adapter for SUP slide-in fins enables mounting slide-in (US box style) fins to both inflatable and hard stand-up paddle (SUP) boards. Designed by Waydoo to work with the Subnado system, the adapter provides a secure connection between the board and removable slide-in fins, simplifying installation and removal while preserving board hull integrity and fin alignment for predictable tracking and stability.
Advantages
The adapter offers a compact, low-profile solution that fits standard slide-in fin boxes, allowing users to convert boards that lack factory-installed US box fittings. Its construction ensures stable fin seating and reduces lateral play during paddling. Installation and removal are streamlined for transport and storage, and the adapter is suitable for repeated mounting cycles without permanent modification to the board.
Suitable for
Inflatable SUP boards requiring slide-in fin compatibility
Hard (solid) SUP boards where a removable fin solution is preferred
Users needing quick installation and removal for transport or storage
Applications where improved tracking and stability are desired
Key specifications
Compatibility: designed for slide-in (US box style) fins and Waydoo Subnado system
Suitable board types: inflatable and hard SUP boards
Mount style: slide-in fin adapter for existing fin boxes
Function: provides secure fin attachment, reduces lateral movement, enables removable fin usage
How to use
Align the adapter with the SUP's slide-in fin box and slide it into position until fully seated. Insert the compatible Subnado or slide-in fin into the adapter according to the fin manufacturer's instructions, ensuring the fin locks or secures into place. Verify that the fin is properly seated and that the adapter is flush with the board before entering the water. For removal, unlock or unfasten the fin and slide the adapter out gently, taking care not to force components or damage the fin box.
Usage recommendations
Use only fins and hardware compatible with slide-in (US box) systems. Inspect the adapter and fin box for wear or damage before each session, and ensure the fin is fully secured to avoid unexpected detachment. Rinse components with fresh water after use in saltwater and store the adapter dry in a shaded location to prolong service life.
