The battle for season powerboat racing bragging rights has come down to the wire, with everything left to play for tomorrow in the National Grand Prix, hosted by the Spanish Point Boat Club.

The national titles in each of the racing classes will be decided during the event to be contested in the Great Sound.

Very little separates rookies Henry Talbot and Andrew Cottingham, and racing siblings Steven and Keith Bridges, in the battle for supremacy in the lightning-fast S class.

Things are also very tight in the remaining classes, including the A class where Shaki Easton, David Selley and co-pilot Matthew Smith, and the father-and-son teams of Jody and Tony Carreiro and Ryan and Richard Davidge have their eyes on the prize.

Points will be calculated immediately after racing concludes to determine the respective class winners.

“There are a lot of points on the line and nothing is decided, so it will be a winner-takes-all situation,” Selley said.

“We’re racing in the Great Sound and hopefully we have a little bit of wind to throw a challenge in there because if it’s too calm or too rough, it’s not fun. But if we get a little bit of a chop, it’s perfect racing conditions.”

Selley added: “We’re hoping for a safe race. Pleasure boaters, please stay wide in the Great Sound and be mindful that there is a race going on, utilising all of the channel markers as bouys as far over to Pearl Island to Hogfish Beacon.”

The race committee has scheduled two heat races to commence at 12.30pm, to be followed immediately by a prizegiving ceremony.

Food and beverages will provided along with a play centre for children in what promises to a fun-filled day for the family.
