If you load the GOLD Intl. version and look at the various ship/sub description screens after selecting each of the vehicles, there are a few loose ends to secure..
Type VII submarine - how many machine guns? Says this sub has quad mounted?
Salmon Class sub - says the submerged maximum range.. but others subs dont say any submerged ranges..
Raiko class - Mispelled Raiko 3 times in one paragraph, Riako Riako Riako..
Only two ships have their hull length listed for comparisons.. Schnellboot and Elco.
All the torpedoes have options to set various speeds which give various max ranges, except the Elco- it is 33knots all the time - and the Lightning which only gives 4 knots of variation from 41-45..
All the other ship/sub torpedoes apparently use the same manufacturer (or are gameplay balanced) and can set speed between 27knots and 44knots for ranges 15000 down to 6400 meters, including the 3rd torpedo boat called Schnellboot. (other torpedo boats are only exceptions to the 27/44knot rule).
Kguns and DC racks are listed out of order between one ship description and another.. Sometimes DC racks are listed before Kguns..not uniform looking for a specs sheet..
All the ships use the words "Tonnage Full or Empty" except the 3 battleships, which use the words "Displacement Full or Empty".
The Hood is the only battleship with a description, leaving the others as a mystery and potentially modified by the kaiserlich marine?
omg! you really are retired huh?
