lol i just finished a thread about what i presume to know of surface operations on both sides of the world, my books tell me that RR is quite correct in that your boat is a surface torpedo attack boat with the option to dive if needed

on the other hand it seems that Dutch boats operating out of Gibraltar spent their days at periscope depth while ambushing Italian freighters off the coast, recharging on the surface at night. And the same Dutch boats operating between the archipelagos in the Pacific did the same thing. Makes sense of course: submerge during the day when near land, since any sunbather could easily see you. but to actually get there you'll just run on the surface and you dive whenever the planes are sighted. same for U-boots as far as I know.
