No racing was possible on day four at the Sailing World Cup in Miami as the wind and sea state became calmer and calmer throughout the day.

Competition was first abandoned in the 49er and Nacra 17 fleets in the morning.

Scheduled races in the remaining seven fleets were then also cancelled in the afternoon on Biscayne Bay, just off Coconut Grove in the Florida city.

"We had some hope because yesterday the forecast indicated that the wind strength would drop at midday but it didn't," said Antonio Gonzalez de la Madrid, World Sailing's technical delegate for the regatta.

"Instead it increased and the average was above 25 knots. In the afternoon the average wind strength was 27 to 28 knots and gusting up to 35 knots.

"World Sailing's Race Management policies prioritise fairness and safety when conducting races. 

"The policies recommend not starting a race when the wind is above 25 knots and this is reduced to 22 knots for the 49er, 49erFX and Nacra 17 when the sea state is rough."

Concluding medal races are still scheduled for five of the fleets tomorrow: the Nacra 17, 49er, 49erFX and men's and women's RS:X.

Medal races in the five remaining classes - laser, laser radial, men's and women's 470 and Finn - are due to take place on Sunday (January 28).
