Mrs. Blubridge Knows Her Ship

Right answer: 0 boats (there are five ships incidentally).  The proprietor of Mrs. Blubridge's Grog Shoppe, the official tipple house of my crew and me and the cleverest website on the Seven Seas, got the right answer.  Mrs. B., if you can send me a bigger picture of your fair mug so's Flarq can see the details better, we'll get you scrimshawed up.  Or he'll scrimshaw one of the McFinster Bros., or one of your employees, or whatever you want.
