Despite the whales living off plankton, krill and copepods, they say the experience was ‘daunting’ due their size but that it was an ‘unforgettable’ experience.

Bill, a trainee helicopter pilot, said: “It was very exciting, something I have always hoped to be able to do.

“The reality is a bit more daunting as these beasts are about fifty feet long and weigh 60 tons.

“We were half a mile offshore with these monsters of the deep and very cold sea temperatures and were well aware of an increased wind being forecast and no other boats nearby.

“I could have touched the one that approached my kayak and Tom had one about six feet under his kayak with a second one coming straight towards him.

“They eat krill so we had no concerns initially over our safety however they are big.
