Thomsen!!
I must beg to differ! With my adjustments, you can get the ships to behave in an acceptable manner in higher than stock wave-heights. True, my mod is mainly for those who wish to use SH3 Commander to alter the wave-heights to "seasonal" or "2X" stock. If you are not using that feature, you probably don't need this mod.
As far as which is more realistic, I guess that is a matter of taste. :p Myself, I like to give players the option! Use it if you wish, if not, your choice.
