William Austin Burt, born in 1792, invented the solar compass to solve problems of magnetic interference in 1835. Burt won an award form the Franklin Institute. It became the US Government's standard surveying tool after its patent expired. The solar compass was a complex device that did not suffer from magnetic field interference.

Francis Pettit Smith was born in England in 1808. Another inventor patented a propeller six weeks after smith did. Smith convinced Brunell to use the propeller instead of the paddlewheel. Francis Pettit Smith invented a successful screw propeller in 1835. The screw propeller had advantages over the paddlewheel. It was lighter, more efficient, and helped the ships not rock.
