With a displacement of around 150 tons (service condition with full coal bunkers) were her dimensions 152.6 x 15.3 feet or 46,50 x 4,6 x 1,50 x 2,70 (moulded depth) metres. According to an item was she similar to the torpedo boats built by the same shipyard for account of the Dutch, Chilean and Austrian navy. The armament consisted of 2-4,7cm quick firing gins and 2-45cm revolving torpedo tubes which were to placed after the arrival if the Goyaz at Rio de Janeiro, Brazil. The personnel accommodation was separated into two parts, officers and warrant officers aft and the sailors fore. She was fitted out with a triple expansion reciprocating engine, a high and a low pressure turbine and two forced draught Yarrow water tube boilers allowing a speed of 12 knots with a very low consumption of coal. On 30 May was the 3 hour trial executed in the estuary of the river Thames in the presence of rear admiral Joao Justino de Proença (chief of the naval commission) (1), captain Jose Thomaz Machado Portella (2) (chief of naval construction) and captain Bartholomeu Francisco de Souza e Silva (chief of the machinery section), belonging to the Brazilian navy. In the 3 hours were 6 runs over the measured mile executed achieving a mean speed of 26,493 knots. The consumption trial in the presence of above mentioned two captains showed with a mean speed of 11,277 knots showed a quite acceptable consumption. Using reciprocating engines and turbines together to decrease coal consumption was an idea of the Italian captain Soliani, Genoa, Italy.
