Length, 98.0 m x Beam, 9.4 m x Depth, 3.2 m
1635 tonnes normal displacement (1458 tonnes standard)
Main battery: 3 x 10.0-cm
Secondary
battery: 2 x 4.5-cm
QF battery: 4
x 1.3-cm
Weight of broadside: 44 kg
10 TT, 45.0 cm (2 submerged)
80 tons depth charges/mines
Hull unarmored
Battery armor:
Main, 2.5 cm shields
/ secondary, 1.0 cm shields
Maximum speed for 26484 shaft kw = 31.50 knots
Approximate cruising radius, 2700 nm / 15 knots
Typical complement: 129-167
Estimated cost, $830,000 (£208,000)
Remarks:
Caution: Hull structure is subject to strain in open-sea
conditions.
Caution: Magazines and engineering spaces are very cramped,
and
lack adequate watertight subdivision.
Oil firing.
Ship has slow, easy roll; a good, steady gun platform.
Good seaboat; rides out heavy weather easily.
Main deck QF guns subject to being washed down in a seaway.
