Project history

Ordered in four groups, the first pair on 16.7.1877, the second pair on 18.11.1878, the next three on 10.2.1879 and the remaining two on 6.12.1880. They made between 18.59kts (47) and 19.84kts (55) on trials, and they were considered excellent boats with good seakeeping qualities. From 47 onwards the hull form was altered slightly and the last pair had one funnel instead of two.

Modernizations

None.

Naval service

They were designated second class TBs in 1883, and were sold between 1896 and 1900.
