Kung Fu: Year of the Tiger by Lee Chang

Kung Fu
Year of the Tiger
by Lee Chang (Joseph Rosenberger)

Eurasian martial artist Mace is visiting from Hong Kong to find his uncle is being forced to pilot his boat for mafia drug runners. Mace and his cousin decimate the gangsters with their Kung Fu skills and recruit the Coast Guard to make a rescue, leading to a Rosenberger trademark of a fight on a large boat.

Mace's style is to use exotically named moves that maim or kill in one strike. At one point Mace kills his enemy by screaming at the right pitch, which hits a vibration that melts his enemy's brains, which begs the question of why he doesn't just do that all the time.
