I could use some help from people who have specs on the boats we have in SHIII, because I can see the values for (I think) disel engine shp and rpm. I am not sure if the values are per engine or both included.
I have started with the VIIb as this is the boat I use the most. The default values are;
SHP 2800
RPM 471
By decreasing the SHP value I can reduce the acceleration of the boat, but this also reduces the top speed.
By increasing the RPM value I can increas top speed without effecting the acceleration (much). So to the limited extent of my testing tonight we may be able to (at worst) reduce the acceleration problem and (at best) fix it. This of course assumes I can get some real acceleration figures for these boats.
I don't think it will be possible to alter the acceleration profile, just the time to a specific speed.
Anyway, here are the tests I got tonight.
Std VIIB
SHP 2800
RPM 471
0-10 6 secs
10-17 45 secs
Modded VIIb
SHP 1800
0-10 8 Secs
11-15 50 Secs
SHP 1000
0-10 16 Secs
11-15 50+
SHP 500
0-10 33 Secs
11-13/14 2-3 Mins (only 14 infrequently)
SHP 500
RPM 600
0-10 30 Secs
11-15 2+ Mins (got back the 2 knots)
Later,
Grayarea.
