While motor-sailing in still waters, I noticed a pod of Dolphins herding Salmon, and catching them by rushing upwards into the school. As I sailed closer, the Salmon gathered underneath the yacht, preventing the Dolphins from swooping upwards. They sheltered there for approximately 30 minutes, waiting for the Dolphins to depart.
