A post pressurizing material treatment for bodies moving through fluid
includes a series of compartments joined to the rear surface of the body.
Each compartment is sealed by a top wall, a bottom wall, a pair of side
walls and a front wall and is open at a rear end thereof. Each
compartment retains at least one V-shaped base having diverging walls
opening into the rear end of each compartment. Post pressurizing material
is secured in a spaced between the walls of the V-shaped base for
trapping fluid flow and accumulating forward pressure between the walls
of the V-shaped base so as to reduce drag and propel the body forward.
