Navigation Outside Of Silent Hunter Software

09-22-20, 04:16 PM

Hello Skippers,

Note: I am posting in this board, this thread would apply to any SH (I think?). Also, I have done extensive searching on the following without any substantive success. If I had, I would not have posted this thread, eh?

Maybe I'm not using the right search terms?

First, is it possible to only use SH without ever looking at the map and only use external tools like, Encarta, Google Earth, Stellarium, paper & pencil, etc.? Seems this would only work if the SH Map was an accurate representation. Is it? Assuming the SH Map is accurate, then it makes sense this could be done.

I have been searching the forums for weeks and have not yet been successful at making any of the "Real Navigation"-ish mods work with my Steam installations. If anyone knows of any fixes for SH Steam, please advise.

Okay, here is my premise, but I guess the only way to determine if it has merit is to just leave harbor and try it, right? So, that is what I will do, but if anyone can suggest any guidance I have no problem not reinventing the wheel.

I will be posting to this thread as a log of my voyage from Pearl Harbor to Midway. Wish me luck!

Exiting berth at Pearl Harbor. Cruising to Barber's Point (SW point of Oahu).

Since this is a navigation test, there will be no enemy engagement.

256° @ 15kts

Exited harbor entrance to starboard. Next check at Barber's Point.

10 Dec '41 0808
294° 15kts
Wx partly cloudy. Wnd spd unknown, est. WNW.
At Barber's Point turned to starboard toward Kaua'i Island 84nm. ETA in 5:36 = 13:44
No sound contacts.

10 Dec '41 1344
294° All Stop
Wx partly cloudy. Wnd spd unknown, est. WNW.
Arrived at predetermined position just SW of Kaua'i, but no island seen.
No sound contacts.

Notes...
This is not expected since Kaua'i Island about 20nm in breadth and over 2,900' in elevation. Inspection of the SH Map shows Kaua'i Island is there, but sub is still 11nm ESE of island. I would expect to have seen it by now.

SOG = 13kts (86%)

Either the knots shown in SH are not true nautical miles or there has been a current or wind against our progress.

271° 13kts
Wx partly cloudy. Wnd spd unknown, est. WNW.
Peak of Kaua'i visible at 1430.
Beach first spotted 1504.
Proceeding to turning point skirting S of Kaua'i. The intent is to pass between it and the neighboring Ni'ihau.
No sound contacts.

10 Dec '41 1543
224° 13kts
Wx partly cloudy. Wnd spd unknown, est. WNW.
Clearing haze reveals more southwesterly heading is neccessary.
Ni'ihau Island is 26nm. ETA 2:00 = 1743.No sound contacts.

An additional heading change to 290°-ish will be needed within the hour. We are hoping to pass the northern tip of Ni'ihau before nightfall to establish bearing for the dark hours.
