Do not fear, it’s meant to be here!!
The bump which can be seen at the back of some of our boards on the bottom is where the drop stitch material has to be cut in order to fit in the inflation valve. To try and minimise the visibility of this we try and hide it under the fins as much as possible however on some of the boards with the US fin box system it may still visible.
The Red Paddle Co Elite boards have 2 Patented Stiffening systems. The FFC system in the front half of the board works by putting a carbon rod under compression. This works in partnership with the RSS system to create an incredibly rigid board. The compression in the systems creates a downward force onto the board. The result of this is that you will see a “bump” on the underside of the board directly beneath the FCC mounts. This “bump” will get a little bigger as the material softens up over the first few months of use. This is normal and nothing to worry about. Your board is not delaminating or at any risk of failure. Please continue to use and enjoy your board as usual.
