"That yacht was Kevin's P-class, he was more the sailor. But we all used to drag a fibreglass dinghy into the water and sink it, then bail it out and sink it again."
Ian, 52, has four grown children but no grandkids yet.
"We lived at the Mount every summer. For the first few years it was in a caravan at the camping ground on the harbourside. We went back every summer right up until our late teens and probably even later."
Their father died last month and Russell died a few years earlier from cancer.
Says Kevin, who still has a little trailer-sailor: "It's a shame our Dad wasn't still here to see the photo being brought out again. He'd be tickled pink.
"The whole family went for each summer over 18 or 19 years."
Kevin, 56, has worked in teaching and clothing distribution and still enjoys beach holidays with his four children and three grandchildren.
Ian and Kevin live in Auckland, while Murray and their mother still live in Hamilton.
Murray's most vivid memory of summers in Mt Maunganui is the year he broke his arm playing cricket and had to wear a plastic bag over the cast when he went to the hot pools.
"Dad also used to take us up the Mount, sometimes on his back. He'd been in the army and was very fit."
Full-time lawnmower Murray, 53, has no kids but will be at the Mount for 10 days from Boxing Day, continuing a tradition of more than 50 years.
