Sensational Sea claims Classic
Sea The Moon preserved his unbeaten record as he romped to victory in the German Derby at Hamburg.
Christophe Soumillon had the Markus Klug-trained colt smartly out of the stalls to overcome a poor draw and grab the rail.
The son of Sea The Stars then hared across towards the near-side rail as the rest of the field panned out all over the track.
Such was his dominance, Soumillon could enjoy a casual look over his right shoulder and saw the opposition had been blown away.
Lucky Lion did best of the rest in second, while sole British raider, Godolphin's Pinzolo, never showed.
Aidan O'Brien's Irish challenger Geoffrey Chaucer weakened quickly under Ryan Moore after threatening to make a bid.
Soumillon said: "I was going so well that I found myself in front very early and just decided to stay there.
"When they came round that last bend I went to look for better ground on the outside of the track. I knew then he was going to win.
"He's a bit like Orfevre (two-times Arc runner-up) in the sense that he's a bit cheeky and is not an easy horse to ride. But I was well prepared for it and everything worked out well."
When asked if Sea The Moon could be competitive in major races in France and England, Soumillon said: "Absolutely. Definitely. Yes."
Sea The Moon was cut to as low as 7-1 to emulate his sire and win the Prix de l'Arc de Triomphe at Longchamp in October.
Sky Bet cut the winner to 8/1 from 25s and spokesman Michael Shinners said: "It was hard not to be impressed by that performance.
"It was hard to believe how far clear he still was despite almost running out on the home turn and he crossed the line on the bridle.
"That apparent waywardness would be a worry but connections have got plenty of time to iron out the kinks and this well-bred colt looks a hugely exciting prospect.
"Tougher tasks await so we're happy to go 8/1 but the same was said about Danedream and she didn't do too badly in Paris!"
