''He's managed to go through the whole regatta with a cool head under pressure."
Mr Wrinch said the club was proud of not just Sam and his sister Molly, who is competing in in the 49erFX but also Bay sailors Peter Burling and Jason Saunders.
''There's a whole raft of them over there. I think the four over there from Tauranga stand a good chance of getting a medal. It's an exciting situation really. The yacht club doesn't know where to look."
Mr Wrinch said the athletes were doing so well and if any of them achieved a medal, it would be ''the ultimate".
World champion canoe sprinter Lisa Carrington's Olympic campaign will get underway tomorrow.
The Bay woman is aiming to make it two in a row by claiming gold in the K1 200m on Wednesday morning.
Her events start tomorrow with the individual women's K1 200m heats underway. The semi-final will also be held tomorrow with the final scheduled for Wednesday morning (NZT).
On Thursday morning her bid to claim gold in the K1 500m gets underway as the heats begin.
The prospect of repeating the double at Rio is daunting, but it's one Carrington believes she needs to keep progressing.
"I always knew that doing the 200 and 500m events is hard, and I'm pretty lucky I have such a challenge with the other competitors and the 500m being such a tough event," Carrington said.
"I'm just really happy to be challenged and having that carrot on the end of the stick, trying to chase something and just looking forward, always on the attack, trying to work harder. That's all you can ask for, that type of motivation."
Peter Burling and his partner Blair Tuke are also scheduled to race again in the 49er FX class tomorrow morning. They are in first place after their first six races.
jason Saunders and partner Gemma Jones are currently in fith place in the mixed Nacra 17 class ahead of the medal race on Wednesday.
