I think Uboat.net is wrong.. (food conversation)

I bet you guys could'vepacked away 14 tons of food in several weeks easy

I heard they were pro being "the most decorated of the Marine Corp"

[U777]

Also note that they needed to carry fresh water supply for whole their trip (sic!), while modern subs just "make" fresh water. Thist must have weighted additional tons.

I thought diesel subs had the same technology except they used waste heat from the engines vs steam.

Not sure youd have to look it up, carrying 'fresh' water wouldnt make sense, because in the conditions of the sub, which Id assume would be warm no matter what, especially traveling under water, Id figure that 'fresh' water that was 'stored away from the beginning' after even a few weeks would stagnant and become undrinkable. Hmmm. something to look into no doubt

Re the fresh water, U-boats had distilling units aboard to make water for drinking and for the batteries. Total storage capacity for potable water: 4070 liters (on a Type IXC)

About the food itself, I would factor in waste and spoilage (esp. bread and produce) and the weight of containers. Also, if the Kriegsmarine operated like other services in wartime, people might have requisitioned more food than they actually used on board, making the remainder "disappear" afterwards, for the benefit of their families. Given the increasing hardships back home, I would be surprised if this wasn't common practice later in the war.

One thing you must consider with respect to comparing modern food stuffs to those of sub days gone by... is the changes in packaging and storage and preservation etc.

A lot of stuff today is freeze dried, or powdered etc.

back then sub crews in the kriegsmarine got the real deal most of the time.

This is true, Im sure they have quite alot of MRE type meals which would reduce the weight a ton, but still provide the same if not MORE calories that normal meals can deal out.

Could also be that crews back then overstocked since they couldn't really be sure exactly how long they'd be out. I dunno how food stores and all that are calculated today, but it's gotta be more exact than it was in WWII. Maybe some bubbleheads could fill in the blanks

I recently read the book: U-Boat War Patrol (The Hiden Photographic Diary )F U-564) and IIRC it stated that 1 litre of water took 1 litre of diesel to create.

In UK/Imperia; measure terms, 1 Gallon of fresh water weighs approx. 10 lbs.
