stay in shallow waters
 

I did already two harbour missions (HATE :nope:) including tokyo, i recommend:

-start with near full batteries before entering harbour bays. you will have no chance of escape if you enter already with onyl 1/2 batteries
-sometimes the first destroyer line can be passed by diesel engine over water max speed
-run close near one coast line, you will have contact with bottom
-look out for some smaler bays for a hide, letting ships pass
-save often.... :damn:

One technique I've used is to wait for a commercial ship to enter the harbor and then hide underneath it matching it's speed and direction. Any patrol boats ignore the commercial ship, and your prop noise is hidden by the ship's props. Getting out of the harbor tends to be easier because the patrol boats are looking outward not inward. :D

Funny you should say that. I remember my dad telling me that's exactly how they snuck into a Russian port back in the 70's when he was riding subs. :arrgh!: I'll give it a try.

Well its now Monday, and my original posts were written on saturday, but ultimately what happened was during the cat and mouse game, the chasers and DD backed off for the passage of a commercial boat. I snagged the opportunity and flanked out of my hole to get behind the merchant. The task force was left to wondering where I disappeared to.

I got my pictures and by the end of sunday night (just before SNF) I was exiting Tokoyo Bay. The whole of the mission was done at 1:1 .. Zero TC.
