The six-man final started with a flurry of waves but it was Scanes who kept busy when the ocean went quiet, connecting a number of quality rides through to the shore while his opponents struggled to back up their opening waves.

Wallabi Point's Luke Reading followed up some strong surfing in his earlier heats to finish second while Pampoolah's Brock Simpson found a number of long rides away from his fellow competitors to finish third.

Bobby Frith, Mick Moltzen and Kai Stanley rounded out the final three placings after progressing through their earlier heats.

Despite small waves and a number of showers throughout the day, the event attracted a record field of 45 competitors and raised more than $2000 for the Manning Hospital Oncology Unit.

Event organiser Kirby Stanley was rapt with the way the day turned out.

"The conditions were pretty tough but everyone was really positive and had a great time," she said.

"We're really grateful to the Old Bar Beach Festival for letting us be apart of it."

Kirby also thanked Brad Morris, who once again donated his extensive quiver of pre-1980s single fins for surfers to ride on the day.

"It's really special," she said.

The Kev Lee Memorial Single Fin Cup has been held every October long weekend since 2015 as a tribute to life member Kev Lee, who passed away from cancer in 2013.

It is scheduled to return in 2020.
