Abstract: The improved snorkel dry top has a fulcrum to which a float member and a diaphragm yoke are attached. The fulcrum has a blocking tab that rests in an aperture in the float member attaching hook when the snorkel is above the surface of the surrounding water. The diaphragm yoke cannot rotate the diaphragm when the blocking tab is in the hook aperture. Therefore, even when tilted, the snorkel remains open allowing free flow of air into the snorkel tube. Another significant improvement is the connection of the float member, diaphragm and yoke to the snorkel top's splashguard mask. This improvement assures that the delicate structures of these components are not exposed to potentially destructive impact forces in the event that the splashguard mask is removed from the snorkel tube.
