I tried to search for threads that would answer this question but had no luck. It seem likely this thread is out there somewhere but I have not found it (them), but the question is......

In the various different versions of "Rant & Roar" "Towasco" "Yankee Whalermen" (Perhaps Ladies of Spain as well.. not sure about that one) etc. that I have heard there is a line that goes... "Untill we strikes bottom inside the two sunkers/sinkers it's straight through the channel it's ......placename...we'll go."

Where/What are the two sunkers/sinkers?

Just wondering out loud

Thanks, Nick
