As I see it you only got 2 choices depending how brave you are from the west nw very shallow waters around 40ft if I remember from the south (obvious choice) dd patrols,sub hunters,etc (depending what mod your playing) there is a gap were were you can sail through about 6km wide with bunkers either side with dds and sub hunters get through them as I recall you got targets gallor including a carrier and a BB ship depending when you go in and don't forget you also got convoys going in and out personally I would scub the mission go in there a do a recon take out the big targets your asking for it especially if a convoy or a TF is sailing in you got no were to hide.
