==Mast specifications==
{{Main|Mast (sailing)}}
The original mast specifications as laid down by the ship's designer still exist and are listed below as "tea rig". This arrangement was used during the ship's time on the tea trade route, where it was necessary to maximise the area of sail to get the greatest possible propulsion when the ship might be becalmed in the doldrums. For the route to Australia it was not necessary to carry such a large area of sail and the masts and yards were reduced. The tradewinds required great strength in masts, but the wind could best be captured by relatively small, high sails. A smaller rig also represented a saving in maintenance and operation costs. Each of the three masts (fore, main and mizzen) is in three overlapping sections.
