John P. Ruane, Jr. owns the yacht, Four Jacks. I linked my source below.
There are four jacks in a deck of 52 cards.
The Four Jacks is flagged in the Caymans, but ownership of this and many other mega-yachts is often not published for reasons of privacy.
In an ordinary deck of cards here are four of every denomination -- one in every suit (one in hearts, one in spades, etc.) There are four aces, four two's, four tens, four jacks and on and on.
