Halifax wind surfers had a marathon day of sailing to raise money for charity.
Twelve sailors took to Warley Moor Reservoir at 5.25am as part of a national campaign, Windsurf 4 Cancer Research.
They didn’t leave the lake until 8.33pm after a gruelling 15-hour stint.
Thousands of sailors across the country took part in the fund-raising surf, now in its third year.
First on the water in Halifax were organiser John Midgely and the youngest sailor, 17-year-old Connor Bainbridge.
As they sailed, moorland fires sent smoke billowing across the lake.
Connor’s mum, Sharon, said: “It was quite worrying for the sailors who couldn’t see the end of the lake because of the smoke, but the fire services did a great job and the sailors were not put off.
“The whole day was just exhilarating for everyone and Connor was so pleased he could take part because he was unable to last year.”
The Halifax sailors used the day to pay tribute to New Zealander Tony Cowley, who sailed as a member of the club for many years. He died of cancer two years ago.
