Looking over my encyclopedia I have come to realize that Romania seems to have enough heavy ships for right now, along with what is being projected to be built. My light forces, are very deficient though. This design is one based off of the OTL Italian Spica class. Be nice, its the first time ive had too play with something this small.

Caution: Lacks seaworthiness - very limited seakeeping ability

It doesn't have good seakeeping, but its meant for operations in the Black Sea, not the Atlantic Ocean.

its cross sectional hull strength needs to be 0.50

she'll resemble a submarine if there's any waves at all when at high speed.

I don't know what .37 seakeeping would relate to in RL, but I think I'd be scared to take that out on a river that was white-capping. I- here and in N-verse- take .70 as the absolute bottom end for anything that can go to sea... and that term includes any lake bigger than Ponchartrain or Okeechobee. There can be some pretty rough weather on the Great Lakes, and I'd think that similar-sized like like the Black Sea would have the potential for similar weather.

And why submerged torpedo tubes???

I wouldn't want to take a ship like that out on a boating pond.

Hmm Ok how about this?

I agree. 28 knots is just sloooow. She might as well sail at 24 knots and become an escort DD or bump the speed up to 31/32 knots in order to cope with other TB's.

OK, but now way too slow to be an effective TB.

The key of a torpedo boat is to deliver several torpedos in a lightning attack, and then run away to reload in port before being sunk by the enemy.
They also should be cheap, and huge range isn't necessary.

For Romania something like this might be suitable

Edit:-

I also doubt romania's ability to build suitable hydraulic engines able to operate at that speed for extended periods.

Well I went back to the 75mm gun, went up to 300 ft long, speeds at 31 knots, and went to a 820 ton displacement, and here she is.

Good seaboat, rides out heavy weather easily

I think this one can go out in a boating pond. The only problem is just about every destroyer in the Black Sea can catch and sink her hence the reason I went with 34 knot speed at first, although I do have my "destroyer killers" for that.

looking good, though 75tons misc weight is overly excessive as most WW cruisers don't have that. for a TB 10-15tons is good. Then you can plow the spare weight into extra speed

Also you may want to change the status of those 75mm guns to DP or QF, and increase the main battery shells as she'll run out jolly quick in a running battle.

You could just buy the Italian Spicas, they are around and are pretty popular.

You really don't need the Good Seaboat mark, just make sure you don't drop below Poor Seaboat.

Didn't even know they were around or for sale. If they are I shall just buy some of them. Suggetion to mods maybe someone should start a ship for sale forum or thread, that way we don't have to go searching through pages of designs.

There are various frigates/corvettes including the Spica Class in this thread. Italian yards should have space next year.
