Thats not all that far from the stats I'd developed, although the guns only get a 14" range unless assisted by the spotter plane since the low position of the rangefinder only allowed them to engage targets out to 7 miles unless receiving external assistance.
"Skirmish" makes it the same as the German Type XXI, but I could be pursuaded to go for Patrol (although I reckon its meaner than a Type VII or Type IX)
