"I knew it [the final] was going well for the first couple of splits but I caught a bit of water and it started to slip away," Dawson said.
"It's not often that there are no 15 second penalties with guys trying to cut lines around the poles and missing gates. You've got to read the flow of water and stay on top so you don't end up swimming.
"It showed the quality of the athletes racing."
The Black Sticks women's hockey team featuring the Tauranga trio of Rose Keddell, Sam Charlton and Gemma Flynn beat Spain 2-1 in a fine performance to keep alive their quarter final hopes.
The Black Sticks have had two wins and a loss with pool play matches to play against world number one The Netherlands and China.
Tauranga Yacht and Power Boat Club members Sam Meech and Jason Saunders were also in action on the turbulent waters in Rio yesterday.
Meech finished 14th and 15th in the solo Laser class in his preliminary races to drop back to 17th place after six completed runs after a promising start on the first two days of competition.
Saunders and team mate Gemma Jones are 15th in the mixed Nacra 17 class ahead of four races held early this morning that will impact greatly on the overall standings.
