what is a snorkel used for please?

[She-Wolf]

hello Community.tis me, paws, only now I have a new ID, as you can see, and my own Avatar ( she is prettier than me). I took the advice of Albrecht as I felt it was misleading for me to have the masculine avatar that comes with the rank, and I wanted a name that gives a clue to my gender so no-one chats with me thinking I am a lad and then gets embarrassed when they realise I am not.

I am in the third single mission and am gently challenged as to how to knock out the second attack boat that comes for me ( the first one I nobbled with a bows-on hit the first try, wowee!). That is not what I want advice on however - I will find out how to do it, eventually, I expect.

The snorkel - what is it for? I wondered if it is to get fresh air in, when the fumes are getting too strong for the crew to live comfortably.

Also there is a little wooden-looking triangle aerial thingy on the deck, looks like it could be good for drying socks on when topside, :rotfl:but I am sure that it has a much more serious use than that - sonar or summat?

thanks as ever
