Hole in the Hull Emergency Procedure

[ekps1388]

I realize I am at the bottom of the nautical knowledge pole and this question may really sound dumb to an experienced seaman, but I still want to know the answer:

In the event of damage of a hole in the hull, could a tarpaulin attached to a jackline be maneuvered over the side of the boat and underneath the hull by one or two crew members from the upper deck, to position it so that the water pressure would hold the tarpaulin to the hole to stop the intake of water there? In other words could this procedure be accomplished without crew members entering the water to attend the damage?
