I rode a snorkeling "smoke-boat" during the cold war around the
Faroe Islands. We snorted from 6 to 8 AM and from 6 to 8 PM,
attempting to copy Soviet radio traffic on tthe ssnorkel whip antenna and charge the "can."
The sea state was definitely not condusive to snorting. We were
experiencing 15-degree rolls at a depth of 150 feet. We lost the
forward portion of our aluminum "sail", and still had to convert our
Fuel Ballast tanks to Main ballast tanks, while on the surface.
Needless to say, our "pucker-strings" were challenged, along with
sinuses constantly draining.
Thanks to our ECM gear, no Soviet ever picked us up, and we obtained some valuable intelligence.
The early snorting U-boats did not have all the safety features that a U.S. sub had, like engine high vacuum cutout, low engine RPM cutout and high back-pressure engine cutout on the outboard exhaust valves. All this was gained from the U-3008 and U-2513
after WWII.
