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".
Yes, exactly. I think it should be accepted here, as well. If it was not, please report it.
Actually "csónak" is not the word for "boat". "Csónak" is very specifically a rowboat.
( I would not attempt to sail across the ocean in a "csónak" but I would be happy to row a "csónak" in the lake. :) )
