'Yacht' or 'sailing boat'

[Polly]

I was doing a Face Time thingy with small grandson; he was toting the current treasure, which was a flashcard picture of a saily. 'Boat' says I all helpfully, 

'Yacht' corrected my daughter, and there on the reverse, was the word in question. 

I started to wonder...I never refer to Briiliant as a yacht, I call her a 'boat', 'sailing boat', or 'sailing cruiser'; why is that? Why have I never heard anyone else on the Broads talk about yachts either?

Polly, hi. Wikipedia give as good a definition as I've seen:

Ahhh thanks! Brilliant is 9ft short of being a yacht then, as are most of them on the Broads; and of course, on reflecton, there are Wherry Yachts    lurking about. ⛵️
