3:33pm - Out on Course E, the wind has reached 12 knots - more than enough to ensure we get sailing today.
The rivals are still deadlocked at 3-3, after light winds made racing impossible out on the Hauraki Gulf. Needing an average minimum of 6.5 knots on the racecourse, the breeze was never consistent enough for even one race to start during the 4-6pm racing window.
The spectators didn't seem to mind - it was still a gorgeous day on the water - and the teams probably appreciated an unscheduled rest day in the midst of an intense contest.
Hopefully, today will be more fruitful and signs are that the winds will be far better for sailing out on the 'back paddock' at Course E, the southernmost track off the coast of Beachlands and Maraetai.
Northeasterly winds of 11-13 knots produced conditions more akin to those we saw on the opening day of the match last Wednesday.
Yesterday's non-result means the earliest the first-to-seven series can finish is Tuesday - if one team sweeps the next four races.
But if we continue the trend of split results over the first three days - and no more days are lost due to weather - we could still be here Thursday.
First race is due to start at 4:15pm.
TAB odds: Team NZ $1.50, Luna Rossa $2.45
