"A Floating Object Displaces An Amount Of Water Equal To It's Own Weight". I read that somewhere as absolute. ...Some kind of LAW of physics..

SO: As this 2700# boat is taking on water..I suggest that once 2700# of water has been "injested"..the boat is SUNK. Since it is NO longer Displacing the water..What say you...?? NB

EDIT: Water weighs 8 pounds per gallon..So 2700 pounds equates to 337.5 gallons. We only have to "Injest" 337.5 gallons of water to SINK the boat.

EDIT 2: Don't forget the PLUG.
I say NO.

Think of “Buoyancy” and displacement of water.

As soon as the boat displaces more water than the weight of the boat, it will sink. So that means it all depends on the shape of the boat and how it displaces water. Take a piece of tin foil and shape it like a boat and it will float. Take the same tin foil and roll it in a ball and it will sink. The tin foil didn’t change in weight, just in shape.

That’s how I understand it.

BTW, an engineer has to know the "area" of a hole for some calculations because if you have an ellipse shaped hole then there really isn’t just one radius. You can have and "area" of 0.7853981633974483 square inches and the hole could be out of round and not just a 1.000000" diameter.
