Subnado US Fin Box Mount

The Subnado US Fin Box Mount is the cleanest way to fit your Subnado to a board that already uses a standard US fin box. Rather than improvising a setup or relying on stick-on mounting, this bracket gives you a neat, purpose-built way to turn a compatible SUP or hard board into a powered-assist setup for relaxed cruising, covering distance, or taking the sting out of wind and current.

For the right board, this is the simple solution. It keeps the setup tidy, secure and low-profile, so you get the benefit of Subnado propulsion without adding unnecessary faff. It is particularly well suited to paddlers who already own a rigid board with a US box and want an easier, more integrated way to use their Subnado on the surface.

Where This Mount Sits in the Range

This is the board-specific US fin box option in the Subnado range. Choose it when your board already has a standard US fin box and you want the most straightforward route to board-mounted propulsion.

It is a better fit than a universal-style board setup when your board is already US-box compatible. On the other hand, if you are building a broader Subnado setup with multiple accessories, controllers and mounts, the Subnado Accessory Box may make more sense. And if you are starting from scratch and want a more complete ready-to-go board propulsion package, it is also worth looking at the Subnado Sea Scooter SUP Motor Package.

Why Choose the Subnado US Fin Box Mount

• The right solution for US fin box boards – no guesswork, no improvised mounting.
• Cleaner board setup – keeps your Subnado mounted in a neat, low-profile way.
• Great for assisted paddling – handy for distance, headwinds, current and relaxed exploring.
• Simple to fit and remove – ideal when you want powered assistance without permanently changing the board.
