I thought that the regatta made it so co-ops with the same amount of members had to race each other. Every other co-op in my regatta has 1 member, like mine, except for the top racer which has 2 members.

It's clearly a player with 2 farms, you can tell from the names of both farms. Is this allowed by fair play rules? Can we all have a back-up feeder farm to help us in regatta? If not, why is this player matched up to a single member regatta?
