Notes - Often regarded as the first submarine class in the world equipped with the "getrimd diesel
   systeem" or "snort system". Also check the O 2, K II and O 16 class details for info on
   even earlier Dutch snort systems.
- First Dutch class for use in home waters as well as in the colonies.
  After this class the distinction between 'O' boats (for home waters) and 'K' boat (for the
  colonies) was not used anymore.
- ?Partially double hull?
* = Source for this data is a WWII (possibly post 1943) personal notebook from an O 19 officer.
