The 40ft beast narrowly avoided the boat as it came crashing back down, sending water flying high into the air.

Mr McLeish, a 67-year-old retiree, said: “I believe the escort was alerting the catamaran to the presence of the mum and the calf.

“We had been watching them and felt the boat was headed on a course that might intersect the spot where the pair had dived down.

“I was stoked to have the camera in my hand and able to get the second half of the breach recorded.

“He only breached the once and then all three started moving north and the calf breached multiple times, but neither adult came out again.

“Less than one whale length separated the male and the catamaran.”
