With just over three weeks left before the German election, the battle has begun in earnest, and politicians have been taking the campaign to some unusual places.
Germans will finally head for the polls on 18 September
It is the pride of the German navy, its only boat in Berlin. The tiny launch bobbed calmly on the waters of the River Spree as the sun sank behind the Reichstag.
This is where my election campaign began, with a background briefing from a leading conservative MP.
On board there was smoked salmon with black bread, washed down with small bottles of beer or glasses of Riesling.
As the boat pootled its way through the German capital, I was treated - along with a small group of local journalists - to our host's views on the future of security policy or the Iran question.
But it was post-election speculation that was the most interesting.
The conservatives were so confident of victory that they were already jockeying for position for the best jobs after polling day.
At the time the view was widely shared that the elections were something of a formality.

The conservatives would simply cruise to victory on a wave of public desire for change.
The beginning of the campaign seemed to reflect this. There were no major rallies, and the nation was really gearing up for the summer holidays.
But as things have heated up, the politicians' response has been to take the election to the beach.
Joschka Fischer, the foreign minister, has been seen splashing barefoot over mudflats on the North Sea with his young Iranian girlfriend in tow.
Guido Westerwelle, the Liberal leader, was photographed playing volleyball in his sunglasses.
I took the tough assignment of a day at the seaside early in the campaign.
The PDS, the successor to the East German Communist Party, was touring the Baltic coast.
At a resort on the island of Rugen around 100 pensioners listened as top candidates gave voice to 15 years of frustration.
For many in the former east, life has been hard since German reunification in 1990, and this is the PDS's traditional selling point.
Some tourists accosted a PDS activist and told her to stop all the whining
But as the small crowd applauded with gusto, a few metres away life carried on as normal.
Children were making sand castles. Parents were erecting screens against the blustery Baltic wind, and dogs were leaping in the spray.
There was also some heckling. Some tourists from the west of Germany accosted a PDS activist and told her to stop all the whining.
"We've been subsidising the east for 15 years," they said. "We've paid for everything here."
"That's not true," she responded. "I pay my taxes too."
This little altercation encapsulated what has since become a key issue in the campaign. The continuing east-west divide.
The PDS has struck up an electoral alliance with disaffected former social democrats in the west, led by an old face in German politics Oskar Lafontaine, once Chancellor Schroeder's finance minister.
The new grouping has shaken up the cosy electoral arithmetic from the start of the campaign with a surging support that has rattled the conservatives' confidence of easy victory.
Oskar Lafontaine has made a dramatic political comeback
Their initial response was clumsy in the extreme.
Edmund Stoiber, the conservative leader in Bavaria, said east German voters were stupid cows who were ready to vote for their former butchers.
If only, he lamented, everyone were as clever as the Bavarians.
The comments, and others like them, have been widely condemned and seen as hugely damaging for the conservatives, especially in the east.
There was a feeling that the conservative campaign was adrift, and there was criticism of the leadership of the candidate for chancellor, Angela Merkel.
Mrs Merkel appears to have emerged from the crisis unscathed
But her handling of the situation has provided an intriguing insight into what kind of a chancellor she might make.
The comments were not helpful, she said, and then returned to her main theme, the government's poor record on the economy.
Her predicted collapse in the opinion polls has not, at least not yet, taken place. The new left alliance has lost votes.
And Edmund Stoiber has been left looking rather embarrassed.
A friend of mine remarked that this showed Mrs Merkel's political education.
Her mentor, Helmut Kohl, was the master of what he called "sitting-out" political crises and scandals.
In other words, doing nothing and waiting for them to go away.
His critics say it was also his approach to Germany's economic problems, which only got worse as a result.
On this score at least, Mrs Merkel has promised to be different and this week she also took her message to the beach.
To the tune of the Rolling Stones' 70s hit Angie, she told a couple of thousand holiday makers that she would reform the economy and create more jobs.
We will see what effect it has on polling day, but meanwhile the key decision in Germany this week was announced by eight men and women in strange scarlet-coloured hats and cloaks.
The judges in Germany's Supreme Court ruled the election can go ahead, rejecting a legal challenge from two backbench MPs who said constitutional procedures had not been properly followed.
So battle will now begin in earnest.
Next week, four of the major parties will hold set-piece pre-election conventions, followed by the TV debate between Angela Merkel and Chancellor Gerhard Schroeder.
Stage-managed, mass-media events will steal the attention from the much more pleasant bucket-and-spade politics of the last three weeks.
