Inflatable freeboard extender


To improve safety during surface abandonment of submarines in poor weather, James Fisher’s inflatable freeboard extender prevents sea water ingress through the hatches.

The inflatable freeboard extender (IFE) system has been designed for application suitable in three scenarios: retro-fit, new build submarines, and submersibles. The IFE solution allows the hatches of a submarine to be opened whilst in rough seas.
