A glow-in-the-dark rescue line throw-bag having a phosphorescent rope line loosely stored in a receptacle having a transparent sidewall. A first end of the phosphorescent rope line is secured to the receptacle, with the central portion of the phosphorescent rope line stored in the rope storage volume. A second end of the phosphorescent rope line may be grasped by a user at an open end of the receptacle. When the throw-bag is deployed, and upon the phosphorescent rope being substantially charged, a rescuee who has fallen into the water may easily view the glowing rope line through the transparent wall of the receptacle as it is being thrown in the air. In this manner, a rescuee may better sight where the throw-bag has landed in the water.
