A black-tipped blade broke through the smooth water ahead. The gently rising fin soon became orca – like a submarine breaching the surface. Unlike the submarine, the orca’s body surged forwards and down again as it slipped once more beneath the calm water.

When the ocean is almost millpond-flat, any disturbance on the water is accentuated by the calmness around it. A blast of whale-blow mist, the rise and fall of a distant humpback or the smooth lift of an orca fin all become centre stage in the surrounding vastness.

While not the excitement of other whale encounters, these solitary moments brought their own quiet joy.
