Old Town Snap in Center Canoe Seat
Here's what other sites are saying:
The snap-in seat snuggly snaps over our vinyl gunwales and stays in place until you pop it out. This seat fits in the middle of all Old Town Canoes with widths of 34" to 37". The rugged design can hold an adult or two children and carries up to 300 lbs. Consider a snap-in seat, oar sockets and oarlocks and you have a rowing canoe.
