Revolutionary design, the Epic Self Bailer allows you to have minimal drag with the bailing system closed, or to quickly and efficiently drain the footwell/cockpit area so you don't get swamped and bogged down in the waves.  Also it can be currently retrofitted to fit some other self bailing systems easily.

Please be aware that replacing a bailer in a composite ski will require a reasonably high level of skill.  There are two bailer types.  The thickness of the flange changes depending on if it is being installed on a Rotomolded or Composite boat.
