floated into position

[Klpno]

Hello everyone
I'd like to ask about the meaning of the phrase "floated into position" in the following context:

I wanted to know: Were the New Isles really as strong and smartly designed as their builders claim them to be? So I made inquiries before committing my money. And yes, the New Isles do exist. They were built at the Port of Krauss, at the main shipyard. The last Isle was launched just a year ago, and it's still being towed to its final destination. I even spoke to workers at the Port, using a radiophone. And while they couldn't promise that the Isles were located in safe places, or that I had an open berth waiting for me and my mockman, they were define about one issue: They had done their best work, fabricating the largest, strongest ships humans had ever known.
Jopale glanced at the cover of his book. From the bluffs overlooking the unlit ocean, someone had taken a photograph showing a wide vessel built from tough old wood. Some of the strongest, most enduring land in the world had been cut free of the Continent and floated into position, then carved into a cumbersome but durable ensemble of hulls and empty chambers. And to make the Isle even stronger, a fortune in refined metals had been fashioned into cables and struts and long nails that were fixed throughout the Isle's body.

Does "floated into position" imply that the wood from which these Isles were made was tugged through water to the main shipyard?

Not to the shipyard, I think, but to the location where they would be anchored.
