Higher speed in trials and refit

[dorn]

During trials ship surpassed design speed by 1 knot.

However it changed after refit back to her original designing speed. I have experience that it usually remain same after refit if machinery has not been changed.

Does anybody know how it works?

That's been something that I've been meaning to bring up for a long time. One game I had a DD I designed for the maximum allowed speed, 35kts. She managed to exceed that in trials and hit 36kts, but any refit would ruin that. Quite a shame and something I hope gets looked at for RtW2.

Did you add torpedo bulges? Those reduce ship speed.

I did some refit for such ships in past and I do not remember they loose 1 knot of speed.

I just try to do refit for my older finished game. I has 31 knot designed battlecruiser that reached 32 knots. Just did blank refit and ship remain in 32 knots.

No. I did not.

However I did FC refit and did not change ammunition so ship was slightly overweight. Could this be really issue that as long as ship is overweight in refit it loose her speed advantage?

I am _very_ uncertain about this, but I vaguely recall maybe watching some YouTube, or reading it on the forums...? Huh, either way, to my knowledge it's probably a bug, as you can or could(?) do the opposite as well. Meaning, if you managed to construct a class that couldn't reach it's design speed, a blank refit solved the issue. Probably because the refits produce a different game file and the "over/under the design speed" does not get inherited, maybe?
Again, take this with a liberal amount of salt, but that's how I remember it.

in my 100 trillion hours of gameplay i have never had a ship have their max speed change after a refit (i don't replace machinery and have never used torp bulges)

I've never seen it confirmed by the developers but I could easily see making a ship overweight during a refit causing the removal of the "exceeded design speed" perk. Both the design speed and the ship's actual speed are recorded separately in the individual ship file so it would be easy enough to program that result.

I don't think I've ever seen this myself but I'm careful about refits for my front line units not going overweight. If I had to guess I would say that was the cause. Have you tried refitting another unit in the class (if you have another) and maintaining the ship within weight to see if it loses the speed perk?

I've never seen the underspeed trait go away unless I performed a refit that changed the machinery but that doesn't mean it couldn't happen. I'm surprised that a blank refit could do it. I would think that at the least it would require either an overweight ship to be brought back within the design weight or the machinery to be replaced.

I just ran some tests.

Minesweeper of Swan River-class laid down with intentional overweight and speed of 19kts. Upon commissioning, design unable to reach design speed and limited to 18kts.

Swan River was then sent in for a blank refit. Upon return to the fleet, Swan River was still limited to 18kts.

Swan River was then sent for additional refit, with machinery replaced and no other adjustments made. Upon return to fleet, Swan River made 19kts.

Conclusion: Replacing of machinery effectively resets design speed defects. While not proven conclusively, replacement of machinery likely also negates positive speed miscalculations.

Yes, changing the machinery sets the craft to "zero". So, a ship that was 'slow' can be 1 knot faster with a machinery refit, but a ship that is 'fast' will be one knot slower. A quirk of the perk.

I designed a class of destroyers with 'Speed' rated engines, which should have made 34 knots. On launch, the first one was down-rated to 33. I immediately sent it into the yard, ordered the machinery rebuilt and gritted my teeth for the expense and 10-month wait. When it came out of the yard... it was down-rated to 32. So I scrapped all 12 of the class and started over.

I've had the slow speed ship result changed to normal by saving the design as a different design and beginning to build again.
