This is correct because fresh water is less buoyant (notice the spelling
there?) than salt water.  The difference, I believe, is about 64 lbs. of
buoyancy per cubic foot of air  in salt water and about 62 lbs. of buoyancy
per cubic foot of air in fresh water.  So, in fresh water, it take less
ballast to sink the boat.  

Good point well taken!
