Abstract
A recreational device in the form of an elongate projectile is described. The projectile has a body including a nose region, a mid-region and a tail region. Preferably, the projectile is provided with a fillable cavity for adjusting its buoyancy. The body has a size, mass, length-to-diameter ratio, specific gravity and contour that facilitate its stable distant travel through a liquid medium such as water. Importantly, the projectile has a specific gravity of between 0.95 and 1.05, which renders it neutrally buoyant in most fresh water bodies. In a preferred embodiment of the invention, the recreational device for stabilization purposes against undesirable yaw, pitch and roll has arcuately spaced, radially extending fins in a tail region of the body. When launched by hand underwater, the device maintains an imparted trajectory and slips cleanly through the water over a great distance.
