I worked at a sailing school that used a variation on that theme.

They would set the blocks in the water and float a 17' Boston Whaler
over it, setting up a sling that would suspend the mooring directly
under the boat when the tide came in.

The trick was to set up a loop so that one cut would set the block free
to drop. The one time the line got fouled it flipped the whaler.

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 ...


The way that old Enoch Winslow did it was to back the truck down to the
water at low tide. and dump it.
then he would bring two wooden skiffs with a couple 6x6 lashing them
together, hanging the weight between them.
The chain was attached to the logs by a thick rope. At high tide he woud tow
the skiffs, chain and mooring bouy to where the mooring was to be set. At
the proper place his helper would take an axe to the rope.
