yankee yachts???

[Wally Kairuz]

i'll be using ''banquet'' for language analysis with my friday classes. what
are ''yankee yachts'' as mentioned in the song?
by the way, ranger rick's comments on ''javex bottles on the tide'' will be
so very useful!
so what are these yankee yachts? yachts with lots of people from boston?
