[QUOTE="DaleH, post: 397979, member: 15636"] [i]Just for fun :D [/i] ... and perhaps educate some about bouyancy calculations, concrete is what is called 'negative bouyant'. This means that while it will sink, its 'wet weight' doesn't equal the 'dry weight', as it actually weighs far less when immersed in water than it does when weighed on dry land. Concrete weighs only 59% of the dry weight when immersed in freshwater and 57% of the dry weight when immersed in saltwater. So a dry 30-pound concrete cinder block weighs only ~18-20 pounds (range due to concrete variability) when used as a boat anchor in FW. But for $2 or free from a neighbor ... it sure is a cheap alternative! [/QUOTE]
