I've done 1400 miles in 21 hours but in a car not on a bike. Personally I think you'll be pushing it even though you've got decent roads all the way. You'll win yourself an hour at the ferry as we're an hour behind the rest of Europe but even then with the hanging around time before boarding and getting off the ferry, you're still looking at 2.5 hours total but 1.5 hours delay.
A few years ago I met a guy on a bike at some services just south of Paris. He had been on holiday with some mates in the south of France and he had to get home earlier than the rest of them. He had a bet on with them and he would win if they phoned his home number exactly 24 hours after he had set off and he answered. He wanted to follow me round the Paris ring road as he wasn't sure which route he had to take. He followed me for a while but then we hit traffic and, after I'd told him what signs he had to follow, he went off on his own. Having got through Paris we took a leisurely run and even stopped for a meal but found him again when we got on the ferry. He reckoned that he had got so tired and dehydrated he had started hallucinating and had been overtaking vehicles that weren't even there so had had to stop for some sleep.
I will, and regularly do, drive a car for hundreds of miles at a time but I find riding the bike much more tiring, probably because of the extra concentration needed. I don't think you'll do it.
