Here’s the seatback for the Perception Sonoma kayak I purchased used:
Mystery 1: Anyone know what the velcro is for?
Mystery 2: There’s a tab on the bottom of the seatback and a slot in the seat:
You can’t tell from the photo, but the tab does not fit into the slot (yellow arrow). It is too long (side to side). You can see from the wear marks (red arrow) that it has been angled into place.
Do you think this is a replacement seatback?
