Design

The Grasshopper class was designed by Nathaniel Barnaby in 1886 and were essentially repeats of the Rattlesnake of 1886. They had a length between perpendiculars of 200 ft (61 m), a beam of 23 ft (7.0 m) and a displacement of 525 long tons (533  t ). They were engined with two sets of Maudslay, Sons & Field triple-expansion steam engines, two locomotive boilers, and twin screws. This layout produced 1,600 indicated horsepower (1,200 kW) with natural draught and 2,700 indicated horsepower (2,000  kW ) with forced draught, giving them a top speed of 19.25 knots (35.65 km/h; 22.15 mph). [1] They carried 100 tons of coal, giving them a range of about 2,400 nautical miles (4,400 km; 2,800 mi) at 10 knots (19 km/h; 12 mph) and were manned by 66 sailors and officers.

Armament

The class was each fitted with one 4 inch Gun and six 3-pounder guns. Two 14-inch (356 mm) torpedo tubes and two additional 14-inch torpedo carriages. 4 reload torpedoes were carried.
