The sound of an engine vibrates in the air and the boat cuts safely through the blue waters of the fairways. In the middle of the Limfjord, a herd of seals has crawled up onto the sandbanks, where they lie and warm themselves in the sun's rays. It is the seal's domain that the boat moves into, and when the pack comes into view, the engine noise is muted so that the boat can glide silently closer. Perhaps a curious, playful seal even swims closer to the boat to see who the strange "fish" is that has found its way into their world.
