Maruyu is +1 luck and Maruyu Kai is +2 luck

+1 luck can fail entirely and +2 luck can fail and only give +1

the same stat stacking as normal modernization applies. If using two ships, each giving +2 to a stat, gives you a total of +5 then two Maruyu Kai will give +5 luck ( which can fail and only give half like any other modernization )
