A device for recreational and educational use includes a substantially cylindrical section having a first end, and a second end. A cavity is disposed within the substantially cylindrical section to receive fluid when the device is immersed in a body of fluid. The substantially cylindrical section decreases in radius toward the first end and present a low drag profile to impinging fluid flow. Control surfaces are included on the substantially cylindrical section. A stabilizer is coupled with the substantially cylindrical section, to stabilize motion of the device in the body of fluid when the device is launched by a user. The device can be hand-launched by a user. Energy storage assisted launch mechanisms are also described that assist the user during submarine launch of the device.
