As a first step in making ready my Norway '40 campaign, I decided to prepare ship's logs for all U-boot types (also exceeding my immediate needs, so they'll be ready for the future).After a basic search on the net, on a nice site (in german, but very easily readable): http://www.u-boot-ar...pen/typen.htmlI found all the data I needed and could start my job.I'll post my spreadsheet on odgw site as soon as they're finished.By comparing my data with the rules, I found a huge difference in batteries discharge rates.starting at full charge and running at 4 kn, every sub in the game will have batteries flat after 45 game turns (x 6 min. ea = 270 min. = 4.5 hours).My data say that, at 4 kn, they will run for a variable number of miles, from 35 (Type IIA) to 94 (Type VIIA), for a runnig time of little less that 9 hours (Type IIA) to 23.5 hours (Type VIIA).I know game should differ fron reality for playability's sake, but this seems a too great distortion.Am I missing something?I decided to shift discharge rate 1 line down, giving a free run at 1-2 kn, 1 cell per hour at3- 4 kn, and so on.I also think that different u-boot types should have a different number of battery cells.I also noticed that type II was very little (around 300 tons), so I felt it deserves only 3 hull boxes, even though this never happens in the rules.btw, in hull boxes number determination, should I compare it to submerged or surfaced displacement?any comment?Nicola
