I guess we could crutch through the numbers.
An average person will conservatively need about 2 liters of total fluid intake per day. If you take "sponge baths" you will need about 3-4 liters per day for cleaning yourself which adds to about 5-6 liters per day per person. Most diesel boat crews are about 30 persons, so your looking at about 150-180 liters per day of clean water. An average diesel patrols for about 50-70 days at a time, meaning 150x50 to 180x70 which equals 7500 to 12600 liters per patrol. One cubic meter of H20 equals 1000 liters so we're looking at about 7.5 to 12.6 cubic meters of space to store the H2O. 7.5 cubic meters is about a box 1.9 meters per side and 12.6 cubic meters is a box about 2.6 meters per side just for sizing.
Seems doable for a 2000 ton boat.
I guess if its not too energy intensive to make fresh water then it would better housing more diesel fuel (since all the energy of the submarine will ultimately be supplied by the diesel one way or another) to make more water than to carry the water itself. Question that would need to be answered is... how many liters of water can a liter of diesel fuel make...? If a liter of diesel fuel can make 2 or more liters of water than it would be better to carry the fuel I guess... so yeah your probably right.
