Coaling (ships)
http://dbpedia.org/resource/Coaling_(ships) an entity of type: GeographicPoint108578706
The era of the steam warship powered exclusively by coal was relatively brief, lasting from 1871 until 1914. Although the French ironclad Glorie and the iron hulled HMS Warrior in 1860 both had coal-fired boilers and funnels, their purpose was to provide additional speed in battle. Sails provided their main propulsion most of the time so, unlike HMS Devastation, the first ship built without sails, these were not true steamships. Although much faster than sail, the lengthy refueling or coaling required by steam ships brought considerable additional risk to the ship and hardship to the crew. These drawbacks led to the replacement of coal by oil.

Although much faster than sail, the lengthy refueling or coaling required by steam ships brought considerable additional risk to the ship and hardship to the crew. These drawbacks led to the replacement of coal by oil. Coal itself also required maintenance. Coal cannot be pumped and, once loaded, it had to be continuously moved to ensure bunkers nearest the boilers were always full should full power be suddenly needed. These problems were sufficiently serious for the Royal Navy to build HMS Queen Elizabeth as an oil-fired ship despite an abundance of coal and a shortage of oil in the United Kingdom.
