The four-day event will primarily take place in Gerroa, with Werri and Windang Beaches serving as back-up venues.

Gerroa's Seven Mile Beach is often considered the spiritual home of the sport in NSW, hosting last year's national championships.

The beach is accommodating for spectators, boasting clean sands and easy access.

Many of the state's big name wavesailors will be competing, along with a number of stars from the region such as 20-year-old rising talent Forrest Ladkin and established legend Brett Goodwin, who is one of the favourites to take out the title.

The exciting sport involves competitors being judged on their wave rides ala surfing, while also being scored on jumps off the back of waves, where they perform manoeuvres mid-air.

"Competitors are judged on the critically and difficulty of the moves they execute," head judge Tim Knowles said.

"It can be quite a sight for beach-goers."

The NSW Wavesailing Association is a volunteer-based organisation that manages competitions.
