Abstract: A combined hat and throwable amusement device is disclosed wherein the hat when immersed in water obtains an aerodynamic stability whereby the hat may be sailed through the air as a saucer-like amusement device. The combined hat and throwable amusement device comprises a hat crown having an inverted bowl shape with a top region and a lower terminating edge. A substantially symmetrical hat brim extends from the terminating edge of the hat crown. The improvement comprises a plurality of slot apertures uniformly located about the hat crown with each of the slot apertures extending partially between the top region and the lower terminating edge of the hat crown. The plurality of slot apertures enable air currents to flow through the slot apertures to increase the aerodynamic stability of the device when the device is sailed through the air. The device includes a bouyant hat band to provide flotation to the device upon immersion in water.
