With the equator behind them and now into the southern hemisphere, Team New Zealand's Camper has decided to split the fleet and attempt a tricky passage through the Solomon Islands.
Camper, along with the other westerly boats Telefonica and Sanya, made the call overnight to pass through the largely uncharted island chain in darkness while the rest of the fleet further east gave it a wide berth.
Camper navigator Will Oxley said he first considered the route more than a year ago, and it was not a decision taken lightly.
"[I] had been thinking seriously about it for a few days. So when we got a wind shift yesterday it was pretty clearly the best option if we wanted to attack the leaders."
The route between the islands of Santa Isabel and Choiseul creates a significant separation in the fleet and, while potentially opening up a number of opportunities, presents a host of challenges, from unmarked coral reefs and massive wind shadows to strange tidal surges.
