I was just reviewing submarine information on the web, being interested in subs all my life. Seems back in WWII the Germans and Americans both had advanced subs but many design differences based on size of the oceans they inhabited and long term mission. The Germans apparently had smaller boats with twin diesel drives linked to the screws mechanically. The Americans needed bigger boats to get across the Pacific so copied the design of diesel train engines and only used electric motors, 2 to a screw. They often had as many as four diesel drives which were used to turn generators. They thus had generators which the Germans didn't need because the German drive motors doubled as generators, but the Americans didn't have to utilize 4 big clutches to sort out what powered what.

Where I'm going with this is - aren't submarines cool? Getting on with it, if you ever watched Das Boot you'll see that in the confines of the subs everything attracted condensed water. The American boats of the time had more electronics, hence they had air conditioning to keep 'em dry.

The accident to the Canadian sub was tragic, but hopefully you got good equipment and a few splash guards or changed procedures will see you out.
