Thanks Hitman, will keep that in mind. And the S-class boats indeed
were real pigs as regards their turning ability! Normann Friedman's
"U.S. submarines through 1945: an illustrated design history" has this to say about the matter (p. 122): "The entire S class (but particularly the Portsmouth-designed S-3 - S-13) had such large submerged turning circles that the boats could not make a quick reverse attack." C**p, I'm not envying the RL crews one bit...
