As Boyrs said we who had allot of obsolete ships could lay down some replacements using half our BP in the period 1901-1905.
I have taken that quite literary, and basically laid down one-for-one replacements of most of the ships getting obsolete in that period (20years for BB/AC, 15 for cruisers and 12 for Destroyers/TBs).
So 01-05 is five years, giving me 57,5BP to play with (115/2).
I have not been very exact with what was laid down were and when, but used the earliest possible year. This is because i have enough slips to pretty much lay down all the replacements at the same time.
The ships involved
3 Armoured frigates of Willem van der Zaan-class (8400ton x3) 25,2 BP: Replacing 3 Evertsen class armoured frigates.
4 Sloops of War, á 4000tons (16BP): Replacing 4 van Nassaun Class sloops.
23 E-class Torpedboots á 700 ton (16,1 BP): Replacing 24 B-class TBs
For a total of 57,3 BPs used.
About 10 of the TBs will be built in Singapore and Batavia, and one AC will also be built in Singapore (witch happens to be my 2nd largest port).

Ahoj!
In anything but the camest seas the 120mm gun is not very useful.
Its effective ROF will be 2-3 rpm.
Open mount on lively, slippery hull, with separate ammunition = bad idea.
Hull width - 8 meters. You have the gun forward. is the hull at its full width here? Low block coeficient, so probably not. But maximum 4 meters from centrline to railing.
Gun - lenght c. 5,5m - trunnioned at one third of lenght. 1,8 metre sticks out, leaving just over 2 metres working area when shooting t the sides.
Look at the last photo and imagine them firing to the side of your ship.

Such a gun on such a ship IS possible, but effectiveness is low.

It is QF gun, so the ammunition is not separate. QF increases the burst ROF but it slows down the sustained ROF.
And i don't really see what the problem is, the ships you point to are only about 1m wider, and have no higher block coefficient.
Also the gun is raised to keep it away from as much sea as possible, and there is some misc misc eight that more then cover the weight of a large platform around the gun.
So i would guess on around 12 round the first minute of fire, and slacking of after that.
But after looking a bit more on destroyer gun, i will add a small shield and drop the shell weight a bit.
3.2m draught is a lot for such a small ship.

3.2m draught is a lot for such a small ship.
Sure, but not un-heard of, most destroyers in the same size category i find has around 3m draught.
So she is deep, but not outside the realm of possibillity.
And i intend to design another class for island partoling in the HOI, she is a bit too deep (and short ranged) for that.
But that will wait untill we start 1906. :)
My original destroyers had draughts of 15+ feet! Thats one of the things Im going to fix here.
