Every co-op starts its regatta adventure in the Wooden League. Based on its regatta results, your co-op can be moved between leagues according to the following rules:
- Co-ops that finish in the top three and collect at least one chest are promoted to the next higher league.
- Co-ops that finish in the bottom three or fail to collect at least one chest are demoted to the next lower league.
- Co-ops that finish in the middle (4th–12th place) and collect at least one chest stay in the same league.
