I have a nice picture of the USS Concord, rated as a gunboat

The USS Concord took part in the Battle of Manilla Bay in 1898. This is a photograph dating from 1891. The Concord was actually a small cruiser, with a displacement of 1710 tons and with 6-4in guns.

The cruiser Apollo from prior to 1904

I have not seen this photograph before of the cruiser Apollo, the name ship of the class built as part of the Naval Defence Act of 1889.

The USS Stiletto picture from 1886

This is a photograph of the American torpedo boat Stiletto, taken in 1886. The Stiletto was wooden and was the first American torpedo boat. The Stiletto was a fast launch built as a yacht.

The gunboat Concord, really a small cruiser

I have a photograph of the gunboat Concord taken in 1891. In this picture, the Concord resembles the small cruiser that she really was. The Concord had a displacement of 1,710 tons and dimensions of 230ft x 36ft x 14ft. The armament consisted of 6-6in BLR and ten smaller guns. The crew was established at 14 officers and 181 men. In the photograph that I have, the Concord had recently been completed. The speed was on the low side at 16.8 knots, but that was all that could be achieved with 3,404 HP. The Concord took part in the attack on the Spanish fleet at Manilla Bay in 1898. The Concord had one funnel and three masts, with a gaff rig.

The American wooden torpedo boat Stiletto

The Stiletto was a fast wooden launch, built by Herreschoff Mfg. Co. at Bristol, Rhode Island in 1885. The little Stiletto displaced 31 tons and had dimensions of 88ft-6in x 11ft x 3ft. The engine provided 359 HP, enough to reach a nominal 18.22 knots. The Stiletto had a raised forecastle (just about 3ft) and a single funnel. The wheel was situated on the deck at the end of the forecastle. The forecastle was narrow and did not go the full width. There is a good photograph from 1886 that I will post, when I can take a photograph.

The Russian cruiser Novik

The German-built cruiser Novik was the best cruiser that the Russians had, although admittedly, it was just a scout cruiser. Much better photographs are now available than we used to have, since Russia opened up to the west. The best all-around cruiser the Russians had might have been the French-built Bayan. The Novik was a novelty, in that while launched in 1900, the Novik was rated at 25 knots with reciprocating engines. Jane's said that 26 knots had been reached on trials. I tried the ship in Springsharp and was able to make the design work, if I used very lightweight machinery:

French central battery ships

I am still amazed that the French kept their central battery ironclad battleships from the 1870's in service into the 20th Century. They were rebuilt, at least. The Reboutable is listed in Jane's with a date of 1876. They were ships with top speeds, as designed, as low as 13 knots. With a single screw, iron armour no more than 14 thick on a complete belt, I have trouble seeing how they provided any useful service besides training. They did provide a number for strength comparison lists, but by 1903, their value was extremely low. They also had the problem of having a narrow belt, almost submerged, with about a 60mm deck on top of that. They had high, unprotected sides.
