Abstract : An article ejector for use in marine applications which uses elastomeric devices for storing elastomeric energy to eject an article. Pressurized water is used for causing the devices to expand and store elastomeric energy at levels for ejecting the article at one of at least two velocities. A valve is provided for releasing the water and causing the elastomeric devices to release the stored elastomeric energy and move the water at a high velocity and force. The devices, water and valve are contained in a support housing connected with a launch tube, wherein upon the release of the stored elastomeric energy, the elastomeric devices move the water through the support housing and into the launch tube for ejecting the article at one of the at least two velocities.
