"Everyone is looking like they can hardly walk now," Meech said. "It looks like we will have some good breeze again tomorrow so I'm going to be super tired after tomorrow's racing.
"The racing really begins then. Everyone is on similar points so it's basically like the regatta starts again because the points gaps will suddenly become a lot bigger."
It is certainly tight among the contenders after qualifying and most of the big names are hovering. Only 16 points separate the top 10 and, ominously, the Australians are well poised with Matthew Wearn moving up into third and Olympic champion Tom Burton sixth after two wins overnight.
Meech has been a model of consistency, finishing second in his last four races, although he had to play catch-up in the opening race.
"It was super hard out there today," he said. "It was really, really hard on the body but I'm pretty stoked to come away with three seconds.
"In the first race I had a really good start but went the wrong way and was quite far back in the pack at the first mark but I had a really good run and then managed to get a couple of boats before the finish so that was really good.
"In the next two races, I was in a pretty solid position the whole way round. Unfortunately, Tom Burton from Australia won both those races. I couldn't quite catch him."
Survival was the main priority for some in the fleet and gear damage was common.
Kontides failed to finish the last race when his sail ripped, and local favourite and Rio silver medallist Tonci Stipanovic limped home with a tear in his sail.
"It doesn't get any tougher than that, sailing in the upper wind limits and with massive waves," Saunders said. "It was a case of getting off the line and sending it.
"I'm really happy to get through in a good position. The points are close so we pretty much start again tomorrow. I will take each race as it comes and keep trying to bank some good scores."
