I remember trying the S boats once... They move like molases in January (or any other suitably cold, winter month). I was only able to get it up to 8 knots at flank (standard propulsion, glassy sea, no wind, etc) on the surface and 3 knots submerged. When I could actually get in position on a target, all the torps would do one of 3 things... preemie, run deep, or dud. Rather frustrating...but then again, this happens with all my torps, regardless of boat/torp type...I've started loading large rocks into the tubes to fire shotgun style at point blank...
