A starboard-side view of the screw steam yacht off a mountainous coast. She flies the ensign of the Royal Yacht Squadron. The 'Eothem' was a class of larger yachts known as auxiliary, rigged so as to be speedy and seaworthy under canvas alone. In addition, the vessels were often fitted with a feathering-screw so that the blades presented little resistance to the water when sailing. Auxiliary steam ships did not carry enough coal to last for the entirety of a long trip, and the fires of the steam engine could be extinguished for days at a time on long voyages.
