"Culminating decades of research, engineer and inventor Ted Ciamillo, an
inventor and engineer in Athens, Ga., who made his name (and fortune)
building high-performance bicycle brakes, created what he has dubbed the
Lunocet, a 2.5-pound (1.1-kilogram) monofin made of carbon fiber and
fiberglass that attaches to an aluminum foot plate at a precise 30-degree
angle. With almost three times the surface area of conventional swim fins,
the semiflexible Lunocet provides plenty of propulsion. The key to the
42-inch- (one-meter-) wide fin's speed: its shape and angle, both of which
are modeled with scientific precision on a dolphin's tail."
