Abstract
A hand-launchable underwater projectile toy having a hydrodynamic body and a novel trajectory stabilizing structure extending from the body and configured to impart a righting-moment to the body during underwater travel. The stabilizing structure includes one or more drag-producing surfaces extending in a non-radial direction about the central axis. In another embodiment, the stabilizing structure includes at least one portion that is user-adjustable to impart a selected steering-moment to the body during underwater travel. In a further embodiment, the toy includes a positively buoyant first portion and a negatively buoyant second portion, which cooperate to urge the body into a selected orientation when the toy is suspended in water.
