Corrected this by 'shoving in' ROW sound mod over RFB, and we're back to normal.
This second torp hit a few feet further back from the first.
There's not much in the ..\data\sounds\ folder so just replacing the sound files is no problem.
NOTE: That
Speed - 3 section at the end need to be 'fudged' a bit for the slower ships.
With this ship
Speed + 3 worked.
It comes down to revs and visual indicators (like bow wave) - A bit messy but we'll get there sailors
