Every time I get a contact, whether on hydrophones, or radar, I check the range that it's being detected at. In this case, I'm usually getting radar contacts just outside of 10nm. So I make two circles and conect a line on both ends for an area I want to cover. Then more circles all connected to make a "corridor". Finally, I put the way-points of my course in the center of each circle.

I was just doing this in my game now and I remembered you asking about patrolling. Oh, that curved line on the left is the edge of my 4 day, 108nm patrol zone. I just wanted to see if there was anything down at those three little ports :03:

I could make a better one when I'm heading back out to sea. One that covers more area without overlapping much. I'll post it then.

I hope this helps:cool:

Thats an interesting way of keeping track of what you're covering, though it seems a little involved. I also wonder how well it takes into account target movement, which is something I've been having a lot of trouble with. I find it difficult to set up a search pattern in a way that will give me decent coverage (still don't have radar just yet, so that may help after another patrol or two), without leaving gaping holes for enemy convoys to slip through...

I also dive to PD & manually check the sonar myself. I rotate 360 deg & see if I can pick up anything. I've found quite a number of targets this way. It's especially effective early in the war as sometimes I pick up a merchant or warship on sonar that radar doesn't.

What do you do when your sent out to an area without a choke point? I'm running RSRDC, which follows that nice map, but sometimes I'm out in the middle of the south china sea, or just off a coast somewhere without any decent concentration point within my patrol area. Do you just try to cover as much area as possible? Or do you focus in on traffic lines in the hopes you'll catch something moving through there?

For merchants (speed ~10 Kts or less) my recipe includes sonar sweeps every hour. If for whatever reason (air crafts, fishing boats, coastal gun batteries) you want to avoid surfacing to get in a proper attacking position, do them more frequently (slower submerged speed, more time to get in position, the "further out" you acquire a target the better).

I actually ended up doing something like this, (The yellow course) Raided Shingu and sunk a 5000 ton merchie with 4 MK10 torps. Before that I only had 5 merchies sunk for 7000 tons. A nice prize here!

Now off to Katsuura! :D

I realized that this kind of search pattern works a lot better on a larger scale over longer distances. In this next pic, I've set up a search pattern to criss-cross along a shipping route withing my patrol area. (The outer circle)
http://img340.imageshack.us/img340/1...hpatern03a.png

Again I used 10nm Radius circles. You don't need the outer lines unless you're just trying to line up the next circle. I draw a 10nm line from each circle in the direction I want to head, then use that to place my next circle. It works quite well and doesn't really take much time to set up. Once you have the way-points connected to the center of each circle, you can hit the "erase all" and you have a clean plot laid in! (Blue line) :salute:

Admiral from the looks of that blue line I'd say your navigator has been hitting the medical stores again. :()1:

:hmmm: So it seems he has, let me check...

It was the helmsman! http://forum.piratesahoy.net//public...ault/keith.gif No wait, it was the navigator! http://forum.piratesahoy.net//public...ault/sailr.gif He seems alright, let me check the firemen... http://forum.piratesahoy.net//public...ult/danse1.gif Hmm...:hmmm: The officers? http://forum.piratesahoy.net//public...ult/par-ty.gif

"It would seem that after our success in the USS Drum that the crew have brought aboard prohibited alcohol and are enjoying it. Because of my successful strategies, and our good fortune, I believe it is my fault that they are getting out of control. I would enact discipline, however since no fights have broken out I may go and try this medicinal beer myself."

"Our crew has become a closer knit camaraderie. I promised that although the Drum is an experimental version of the so called "Gato" class fleet boats, we have done well and deserve a bit of fun. After ariving at Pearl, I gave all the good men a month of R&R. "

Now back to patrolling and teaching these Japs that they cannot and will not defeat a free thinking people.

Just remember the game lag is a dead give away ships are in your contact zone, the problem is your guys won't find them to later war. I'm sure you've noticed your PC lagging out from time to time, usually before you run into a target. The problem is when it lags and you miss the target.

Try to think of it like this. Imagine your best crew and best equipment. Say both have the ability to reach out 25nm's at their best. This contact zone exist around your sub from the very beginning, but since you don't have the best stuff you'll not get the contact, just the lag as ships have entered the contact zone. You'll only get real contacts from your crew based on the level of ability, so early war your ability may only be 12nms.

Your men may suck early war, but you don't. You get the PC lag, go to sonar as you can hear what they can't yet hear. You get the sonar bearing and you can head that direction.

As your crew improves and you get better equipment, the lag will be less and less. Late war you may get little to no lag as they now pick up to the end of the zone.

If you're playing RSRD, those patrol stars are a waste of time. Do em and get one over with, then go to where historical action is.

Another thing to rembember, even if you don't use RSRD, stock still has many of the invasion forces and battle, just many of the dates are wrong, locations and size of the force.

Stock will spawn convoys about anywhere, but the best convoys and TF will always be in campaign areas. Pay attention to carrier planes, you know what planes are on the carrier, you know a carrier is near.

I always start out of Manila. Even stock has some of the invasion forces that hit the Phillippines. I just attacked the large invasion force on Dec 12 that hit the Phillippines. A good one with RSRD is the one just above the San Bern Straits as it has several Chistose carriers and Large liners. After sinking a few I hurried to Surabaya and docked and headed to a lil North of Singy and attacked the invasion force near the Malay. I then watched the Japs attacked the British BB's and sink them, back to Surabaya for a refit to have time to attack the large Java force of 50 plus ships. Hurried to Darwin for a refit to have time to find the Carrier group that comes into the Indian ocean.

So many complain of no ships in RSRD..My last two patrols I've attacked 2 large TF and 3 large convoys....didn't have to mess with one single ship.

Soon I'll be headed to the Solomons... Plenty there and near Rabaul 42 and 43. You have a large invasion force at Lae with some ships you seldom see. Then the large battles near the Sols..

Shoho invasion group.
Coral Sea
Battle of GC
Sava
Santa Cruz

Plus several medium size battles, most surface battles, but fun to watch.

I found the best place for action 43 is the Truk/Home Waters shipping lane, just sit about 470 NM N or Truk and 270NM East of Saipan...thats a honey hole. You'll get several flash messages for that area, so get there if you can.

Admiral8Q 05-27-10 04:34 PM

I like picking off lone merchies in small shipping lanes and raiding harbors. I guess that's why I love the Narwhal so much! :haha:

Once after sneaking into Truk and torpedoing a big merchie, the DD came heading for me. I fired my last torpedo and hit him on the bow. He sat there with his nose in the water and arse sticking out. After a couple of hours, and with CO2 rising, I surfaced and finished him off at night with the deck guns!
