I think the problem is that I want do it all at once, and that doesn't work so well
Right now, my tenative 1931 plans call for 4 factories to produce 2 type 0 slips and 1 type 0 drydock. I also want to start develop naval facilities at Paramaribo and Matadi, with at least 0 slips for local productions.
I should toy with just doing the 2 slips and discard or wait on the drydock.
...drydock.
So- any rules for floating drydocks?
Edit : Sidenote- the "6 for an extra director and provision for indirect bombardment" on the Gruno and Tijgerhaai comes from a Wikipedia note on the 1926 gunboat Flores - "their main asset was an advanced fire control system that made them very accurate in bombarding shore targets "- which I'm trying to establish storyline wise.
As for the Minelayer, Alikchi spurred me a bit and I tried several varients. I wanted to keep it small, but the mine loadouts were poor after the other necessary elements added.
The Minelayers are the greater concern, as the coastal minesweepers I'm building will at least serve defensively, and I have 20 of the old sweepers.
So- prototype

Hull space for machinery, storage, compartmentation is adequate
Room for accommodation and workspaces is excellent
Ship has slow, easy roll, a good, steady gun platform
Excellent seaboat, comfortable, can fire her guns in the heaviest weather
Trying to provide for a high-speed self-escorting minelayer.
I'm envisioning
The gun layout is one twin 100mm mount forward of the superstructure, then a funnel with the second twin 100mm mount just aft of the funnel, just above the step in the hull. This should give a decent arc of fire. The rear half of the ship is given over to the mine deck.
Of the miscellaneous weight, 67 is for the electric motors (for silent night ops), 50 for true miscellaneous (sounding gear, magnetic detectors, night vision gear, etc), and 350 for mines.
