Unless you own a floating work barge with hoist, you will need
professional assistance to transport the block and plant it.

maybe you could get it into a cheap wooden dingy, tow it out to where
you want it, and then use large amounts of 4th of july fireworks to
"dramatically" plant the mooring on the bottom. if enough explosives
were involved i'd pay 5$us to see that lol ...
