Scores of two fourths and a third saw the Brits produce their most consistent day in Guanabara Bay to move up from 10th to sixth in the overall standings.
With tomorrowï¿½s Medal Race worth double points, the 29-point gap between themselves to Mathew Belcher and Will Ryan (AUS) in third place is too great for Patience and Grube to make up.
But with the pair having only been sailing together for eight months, after Patienceï¿½s partner Elliot Willis was diagnosed with cancer in late 2015, Patience could not be happier with how they have performed in this event.
He said: ï¿½I am just so proud on how we approached today and how we executed it. I feel quite emotional right now because I am so pleased on how we raced this week.
ï¿½Two months ago we were miles off feeling like we could sail at the front of the fleet, weï¿½ve only had eight months to prepare for this race and I am walking away with my head held high.
ï¿½Whatever happens tomorrow, I really do feel today was one of our finest executions of what we had to do when it mattered. Itï¿½s a very pleasing day, we didnï¿½t come here to finish fourth or anything but there is always something to take away.
ï¿½Itï¿½s been a tricky week, as it was always going to be. I can think of three moments through the whole weekï¿½s racing, coulda, shoulda, woulda, that might have changed our fortunes but that is the beauty of hindsight and the curse of it as well. Weï¿½ve exceeded what we should be doing with eight months of work together.ï¿½
All school children can try sailing for free in Patienceï¿½s home nation at Yorkhill Quay on the River Clyde, Glasgow as part of the RYAï¿½s Sail for Gold Roadshows from 10am tomorrow and Thursday.
All comers are then invited to watch the 470 Menï¿½s Medal Race and cheer the Brits on with friends, family and members of the British Sailing Team from 5pm.
At the same time as the British men were enjoying the best day of their regatta on the Ponte course, so their teammates, Hannah Mills and Saskia Clark, were sailing to gold on the same race area.
Patience added: ï¿½We are such a united team and I am so pleased for them. They are well-deserving winners. Weï¿½ve worked alongside them for many years together so Iï¿½m an old friend of them both and they really do deserve it. They worked hard and what a bang for them to go out on.ï¿½
