Over the following years, Henry developed a rocket apparatus that could be shot from the shore to a wrecked ship. A roped pulley system would be set up to then winch survivors back to shore: an early design of the Breeches Buoy. He also went on to design an early cork Lifejacket as well. He then spent decades and over £300,000 of his own money, travelling to London and campaigning the Admiralty to take up his inventions.
In life he got no recognition for his ideas and it wasn’t until his death that his ideas became adopted and widely used, saving many lives across our coastline.
