Howth Yacht Club's first-day leader Sienna Wright has dropped to fourth overall but just three points off the ILCA 6 Female fleet leader after the second day of racing at the Youth World Sailing Championships in Brazil.

Two second-place finishes fired Adriana Castro Nuñez (ESP) to the top of the ILCA 6 female standings.

The Spaniard finished seventeenth and fifth in Monday’s two races but stormed to the front of the fleet on Tuesday.

Castro Nuñez finished behind Roos Wind (NED) in the day’s opening race, with the Dutchwoman sitting third overall.

“It was a great day,” said Castro Nuñez. “I am really happy with my performance.

“It was quite a complicated day. When we first came out, it was a bit cloudy, then the sun came out, then clouds came back again, and it had quite a big impact.”

Separating the pair is Emma Mattivi (ITA), who earned her second bullet of the competition in race four.

New Zealand’s Naiomi Ferrissey finished third in both races to rise up to seventh, just 10 points off the summit.

Four Irish boats and six sailors are competing in Armação dos Buzios.

29er Female

Lucia Cullen and Alana Twomey (Royal St. George YC and Royal Cork YC) lie 11th from 25 in the Female Skiff 29er class.

Leaders Ewa Lewandowska and Julia Maria Żmudzińska (POL) continued their fine form with a pair of bullets, but their winning streak was put to an end in the day’s final race by Tea Zeeberg and Cornelia Widestam (SWE).

The Polish pair won the day’s opening two races to make it five victories in a row, edging nearest rivals Fleur Babin and Sarah Jannin (FRA) in race four.

Jule Ernst and Louisa Schmidt (GER) then posted a pair of second-place finishes in races five and six to move up to sixth in the standings.

They sit just behind Zeeberg and Widestam who hauled themselves up to fifth with victory in the last race of the day, breaking the Poles’ winning run in the process.

“It feels very good to be the first one to break their streak,” said Zeeberg. “It is always fun to win the last race of the day and be the first one in.”

29er Male

Ireland's 29er European Champions Ben O’Shaughnessy and Ethan Spain of Royal Cork YC and the National Yacht Club continue in seventh place after six races sailed in their 30 boat fleet.

Karl Devaux and Hugo Revil (FRA) remain top of the 29er male standings after picking up their third bullet of the competition.

Devaux and Revil won the first race of the day, finishing ahead of nearest challengers Alex Demurtas and Giovanni Santi (ITA) and Sean Kavanagh and Max Celliers (RSA).

The South African pair sit fourth overall after another third-place finish in race five, finishing behind Charlie Gran and Sam Webb (GBR), who claimed their first bullet of the competition.

The Brits now sit third overall, six points behind second-placed Demurtas and Santi, who finished second in all three races, as Cameron Law and Christopher Lam (HKG) took victory in race six.

“It is very good to have this consistency because it was a really difficult day, the wind was very shifty,” said Demurtas. “Other sailors didn’t sail as consistently as us so it is a great feeling for us.”

ILCA 6 Male

There is little to separate those at the top of the ILCA 6 male class, as David Ponseti Mesquida (ESP) and Luka Zabukovec (SLO) both earned victories.

Ponseti Mesquida took the win in the first race of the day, finishing ahead of Erik Norlén (SWE) and Max Stiff (GER), and now sits in fifth, seven points behind leader Hidde Schraffordt (NED).

Norlén is just two points off the top after finishing fifth in Tuesday’s second and final race, which saw Zabukovec take victory ahead of Mattia Cesana (ITA) and Anton Messeritsch (AUT).

Fiachra McDonnell of the Royal St. George YC is lying 20th from 48.
