| Notes | - Boats had pour stability (up to 35º
list while surfacing) This was improved by widening the middle main ballast tank #2 in 1936/1937 and reducing "top weight" by removing both 4 cm machineguns and one air conditioner (year unknown). After these modifications it was reported that O 14 (and probably her sister ship as well) had good stability. - First Dutch boats equipped with a low pressure lens blower and electric raising/lowering of the periscopes. |
