BERLIN (Reuters) - Italian motorboat world champion Massimo Rossi died on Sunday following a crash during a race in Germany, police and organizers said.

The 24-year-old was catapulted out of his boat during a turn in a race on the Moselle river in southwestern Germany, hitting a tree, local police said.

The 35th international race at Traben-Trabach was stopped following the crash.

"This is the worst thing I could imagine," said Wilfried Roecker, head of the German motor yacht federation.
