Total distance under steam and sail, 36,466 miles.
(B) THE CRUISE OF THE ‘SUNBEAM.’
Reprinted from the ‘Times’ of December 15, 1887.
The 'Sunbeam' reached Portsmouth Harbour on Wednesday after her long voyage of 36,000 nautical miles among the British Possessions in all parts of the world. We are enabled to give the following short account of this very interesting cruise.
For certain duties of the navy, such as protection of the revenue, supervision of fisheries, the police of the Pacific, instruction in pilotage, small vessels are required which will be thoroughly seaworthy, capable under sail of taking full advantage of the winds, and in calms making fair speed under steam with a low consumption of fuel. It is believed that such a type is represented in the 'Sunbeam,' and that her performances during an extended cruise recently completed may be of interest in a naval point of view.
The principal dimensions of the hull and spars of the 'Sunbeam' are as follows:—Length between perpendiculars, 137 ft.; beam, 27 ft. 6 in.; depth of hold, 13 ft. 9 in.; displacement in tons, 576; sail area in square yards, 9,200.
In fourteen years of active cruising in all parts of the world the seaworthiness of the 'Sunbeam' has been thoroughly tested. Neither when lying to nor scudding has she ever shipped a green sea. She can be worked with a complement of eighteen seamen and three stokers. She can carry an armament of machine and quick-firing guns.
The consumption of fuel may be taken at three tons in twenty-four hours for a speed of 7¾ knots; four tons for eight knots; and seven tons for nine knots. The measured-mile speed was 10·27 knots. Seventy tons of coal can be carried.
Under sail alone in the most favourable circumstances 13 knots is an extreme speed. Three hundred knots have been made good on a few occasions, with some contributions to the day's run from current. On a passage the average distance made good is 1,000 miles a week, of which one-third is under steam.
