Wow! So if I unclamp my outboard motor, tie a rope to it and toss it
overboard, then I'll ride higher in the water so I can cast further!

By golly, Don! You finally got one right. This here physics stuff ain't so
hard is it?

I believe that we have a correct answer.



What's interesting is the boat would ride higher in the water but the
level in the tank would remain the same.
