Translation:The ninety-ninth ship is not green.
The internet says you can put a boat on a ship but you can't put a ship on a boat. So, bigger vessels are "ship" - "hajó". Smaller vessels are "boat" - "csónak". But not all boats are "csónak". A "csónak" is a really small vessel, like a life boat on a ship. Steamboats, smaller, steam-powered vessels that were used on rivers, would still be called "hajó": "gőzhajó". You can't really walk around in a "csónak".
