The propulsion system is an integral part of ships with shafted propellers being the most popular configuration, as it is effective over a broad range of applications, despite all the hindrances mentioned in my previous post. Nonetheless there are many alternatives introduced over the years, attempting to improve the efficiency and limit the negative aspects….

Various efficiency ratios, covering ship design
Propeller is the primary driver, but can also be a major hurdle
Basic physics law, in order for an object to move, it needs to overcome its resistance. In the case a ship it is divided in several components, as explained in the previous post. In that article, we’ve focused on the impact of the frictional component of the overall wetted surface and then on the wave…
