The wind might be mild, but the competition will be fierce.

Eight crews representing 11 nationalities will compete in Singapore this week as the Extreme Sailing circuit makes its second stop of the year, following the opening act in Muscat, Oman, in early March.

Light winds are predicted and that will require a change in tactics for the normally speedy races, said Red Bull's Roman Hagara, a two-time Olympic gold medalist who is yet to win on the circuit.
