There is not much wind where they are according to tracker and windy, 4-5kts.BREAKING NEWS
It looks like BIOTHERM is heading towards Mar del Plata in Argentina. They potentially might not Finish this Leg.
They are still racing as far as tracker and social media are concerned, using the engine would be faster than ~2kts.
Even if they go for a closer harbor than Itajaí there is still the option to suspend racing for a minimum of 12 hours, do a (temp) repair, and still get 2 points for the leg. Obviously depends on the kind and amount of damage.
(They are still more than 100nm from the finish. No suspension of racing that close to the finish.)
