This was done by reducing her spars to a light pair of lower masts, without any yards across them; the only break in their sharp outline being a small crow's-nest on the foremast, to be used as a look-out place.

The hull, which showed about eight feet above water, was painted a dull grey colour to render her as nearly as possible invisible in the night.

The boats were lowered square with the gunnels.

Coal was taken on board of a smokeless nature (anthracite).

The funnel, being what is called 'telescope,' lowered close down to the deck.
