Sea ships max speeds

[IckyATLAS]

I have clocked all sea ships over a 1 km distance to measure their maximum speeds.

They have had 1 km from start to reach max constant speed  and then they have been timed with a chronometer over a 1 km distance.

Here are the speeds ordered from fastest to slowest.

Conditions are blue sky, zero windspeed, ad Sea State to 0.

Speeds maybe different with high seas and wind but this is up to you to check. 

 

1 ) Torpedo boat 5s11b213 max speed : 95 kph / 51,3 knots

2 ) Torpedoboat 38 max speed :               85 kph / 46 knots

3 ) Destroyer 7 max speed:                        69 kph / 37,2 knots

4 ) Fastboat 1124 max speed :                 40 kph / 21,6 knots

5 ) SubSh10 max speed:                            25 kph / 13,5 knots

6 ) Sub2b max speed:                                 23 kph / 12,4 knots

7 ) Large Cargo ship max speed:              19 kph / 10,3 knots

7 ) Landboat max speed:                           19 kph / 10,3 knots

8 ) Large Tanker max speed:                     17 kph / 9,2 knots

8 ) Large Tanker Ger max speed:              17 kph / 9,2 knots

 

When you mix those ships in a convoy then it is wise to look for the speed differentials and the way ships are set up in the column.

Faster behind , slower in front with a faster as leader. 

Fast, Slow, Slower, Fast. ?

Thanks for your test.

 

It will be useful.

[IckyATLAS]

I can also add that all ships have been tested with waypoints standing at over 25 km without any problem.

It seems that the initial issues we had when waypoints were at more than 6 or so km has be solved or corrected.

That’s pretty fast for these kind of boats.

95kph, even for these torpedo boats, is not so realistic. But I trust your test and thanks for that

Just for the info these tests are made using the internal editor ruler used as a reference for distance.

I have set three landboats one behind the other perpendicular to the race line every kilometer on a course of 4 kilometers as measured by the internal editor ruler. 

In this way I get a good visual reference when looking from the landboats to check when the boat crosses the line.

My visual reference is precise and the chronometer I used is excellent. The error which is related to my reaction time on the chronometer when I see the boat crossing the line that is the mid axis of the landboat is higher for faster boats than slower ones but I would say something like a quarter of second at worst.

This create a tolerance on the value of about +/- 0.6% for the faster boats to +/- 0.1% for slower boats.

This will convert to a speed error of 0.6 km/hr for the top speed boat (Soviet torpedoboat) and 0.017 km/hr for slowest boat (Tanker)

All this is negligible. The BIG question is how good is the ruler. Here after is how I checked it.

 

I did the following. The Soviet Destroyer of the Class 7, was a Storozhevoy class destroyer which operated in the black sea. Its length was 112.5 meters.

So I place the destroyer on the editor kuban sea map, enlarged it to the maximum of my screen which is a full 4K 43 inch and guess what, the ruler shows exactly 112.5 meters for the length of the destroyer. 

Conclusion the kilometer distance used to set the reference lines are very accurate and the ruler is very precise, hence speeds are correct.

Now do they correspond to the real performance of the ships, that is another story.

The known maximum speed of the real Storozhevoy class destroyer was 40 knots. I have measured 37.2 which is somewhat under so pretty realistic.

 

For the torpedoboat of the G-5 class to which the one in IL2 type 5s11b213 I have found in the literature a miximum speed of 53 knots.

My measurement is 51.3 knots just under that value, very realistic too.

 

So all this means that those boats were damn fast for their time, and are very well simulated, and above all, the IL2 maps and objects are of an excellent precision.

Congratulations to the Devs. This simulator is just the best on the market and improving by the day.
