HI,
No Sailor Steve, Non of the engine speeds are the same. They are all a percentage of Flank and can easily be set to whatever you want. Open the submarine folder, select a boat and open .cfg. Here you can make the changes to various things including engine speed. I altered mine so that Standard equals 10 knots, that way I get maximum range without ever running out of fuel. I use 2/3 for patrolling.
