I'm missing something here. How can the boat lift in static
conditions when the mass is unchanged. "Lift" defined by displacing
less water. How is the boat made lighter?
By the way, please keep on inquiring. Very interesting work.
PS Sorry group for three repetitive posts above. Not sure how that
happened - I hit stop after send, once, as I wanted to edit
