All three of Helensburgh and Lomond's Olympic sailing heroes will be in action early on Tuesday - and for two out of the three it's the moment of truth as they make their final push for a medal.

A lack of wind at the Enoshima Yacht Harbour put paid to all of Monday's series and medal races - and leaves four races on Tuesday in which Team GB are hoping for a medal.

First of the local hopes in action on Tuesday are Rhu's Charlotte Dobson and her 49erFX crewmate Saskia Tidey, who are in action at 4.33am. They lie fifth in the overall standings after a challenging final day in the opening series on Saturday in which they finished 15th, fourth and 18th in the day's three races.

Then, precisely three hours later at 7.33am, in the last of Tuesday's medal races, it's the turn of Anna Burnet, from Shandon, and her partner John Gimson in the Nacra 17 mixed multi-hull class.

They came fifth, second and fourth in the final three races of their opening series, also on Saturday, to lie second in the overall standings behind Caterina Banti and Ruggero Tita of Italy.

Team GB's other medal hopes on Tuesday rest with Giles Scott in the Finn class and Dylan Fletcher and Stuart Bithell in the men's 49er category.

The last of the local sailors in action on Tuesday is Rhu's Luke Patience, who will partner Chris Grube in the last series races in the men's 470 class.

Patience and Grube lie fourth in the overall standings in the category ahead of the final two series races after two top 10 finishes on Saturday.

Reflecting on Saturday's action, 34-year-old Patience said: “It wasn’t our best day but it was good enough to keep our eye on the prize.

"We are still in the fight and we can go to our beds knowing we can fight for any colour of medal still which is all you can hope for. To be able to say that is vital.

“Conditions have been hard today actually. The wind strength in our boat, she’s never flowing quite beautifully. You are fighting for the speed, there’s not much flow. Just fighting, fighting, fighting for the speed.

"Our class is very dynamic because we are able to use our kinetics and bodies to pump the sails so it was a full battle. The heart rates were high.

“Downwinds were nice though because there was good waves, but upwind, that was a war. A war all day.”
