Hi Kurt,
@3kn=164hrs,@5=68,@10=11,@15=2. Realistic max uw speed not quite 16kn for abt 45min. Acc to Roessler, U3507 in experimental configuration (With many flooding slots closed flush) reached 16.5 kn for abt an hour. It was calculated , that the resistance of the flooding slots amounted to abt 28% of total form resistance. Above speeds/time with a theoretical full battery and a clean hull = not exactly combat condition after 2 mo on patrol. :-)) Rgds, RB
