The team included Jessica Pearse (driver), Samantha Hedley (observer), Leilani Cartledge (skier) and Senna Hedley (skier).
A new record time was also set in the under 16 expert class by Elm Street - a team which comprised of two father-son duos including Kody and Wes Davison and Liam and Paul Ford.
Their time capped off a successful day for the local team, with their F2 boat finishing third in the under 12 division.
