Bulli are just one win away from claiming their first George Bass Surf Boat Marathon title in 12 years after another convincing stage victory yesterday.
A win on today's leg from Tathra to Pambula will seal the overall victory in Australia's toughest surf boat race.
Yesterday's win, Bulli's fourth of the seven stage race, came on a shortened course after organisers decided conditions were too dangerous for the scheduled 38-kilometre row from Bermagui to Tathra.
It was the second time in the race that conditions had forced organisers to re-route boats, with Moruya beating Bulli into second on an altered course on day one.
Bulli sweep Paul Jones said it was his crew's best performance of the race so far.
"The guys seem to be getting stronger and more determined as the week goes on," Jones said.
"We had a really good start and all the guys just really dug in to consolidate the victories we've had already.
"We won by just over six minutes which is the biggest margin we've had so far."
Jones said the change to the course, announced not long before the scheduled start, didn't throw his team off their rhythm.
"We were supposed to go to Tathra [from Bermagui] on the big long leg but a big southerly change at about 30 knots moved through before the race and the organisers decided it was too unsafe to go to Tathra."
