Water Jet Propulsion




marine insight

By Ajay Menon | In: Naval Architecture | Last Updated on September 25, 2020

Ships are enormous structures, weighing anywhere between 100000 tons and 500000 tons. Yet, they are moved with ease across the earth’s oceans.

At the other extreme of the vessel size spectrum, small fishing trawlers and pleasure yachts barely weigh over 10000 tons. They are commonly found speeding along the coastline at very high speeds.


So how are such different vessels and boats powered across water?

This is where marine propulsion comes into the picture.

Different vessel classes utilize various propulsion systems that use several techniques for generating power. Earlier vessels used fossil fuels such as coal to run large engines powering propellers.

Later models worked using reciprocating engines and diesel-run marine engines that

Sacrobosco’s Sphaera in Spain and Portugal


First Online: 24 January 2020



This paper analyzes sixteenth-century commentaries on Johannes de Sacrobosco’s Sphaera in Portuguese and Spanish. Between the fifteenth and seventeenth centuries, there were more translations of the Sphaera into Castilian and Portuguese than into all other European vernaculars combined. A major reason for the interest in Sphaera translations in Spain and Portugal was that the basic astronomical and geographical knowledge contained in this text could be used for navigation. Because of their enormous interests in overseas exploration and colonization, Iberian monarchs supported the development of cosmography, a subject that combined mathematics, astronomy, and geography. The astronomical information in the Sphaera was also valued on the Iberian Peninsula for its
