Swinger's keel? Is this a typo, or something needing antibiotics and a private ward?

Alright, I made up that phrase. I just read this, on the SUPERYACHTS.COM page:

The new ketch will be built to feature an aft deck spa pool, two large tenders stowed below the foredeck and a swing life centreboard enabling the yacht to slide into shallow lagoons and waterways...

What on earth is a swing life centreboard?

Here's the page: http://www.superyachts.com/news/alloy-yachts-start-construction-on-a-new-564m-ketch-1550.htm

If it's got a spa pool on the aft deck, you were probably right with your thread title !

The "e" is close to the "t" on the keyboard!
