Category: Main Special Purpose SeaClear SeaClear II


This is the latest version of SeaClear, intended more for recent systems running Win 2K/XP, I believe.

There are 2 earlier versions of SeaClear, as well:

"SeaClear for Windows 95 up", which I have also tested and run.

"SeaClear for Windows 3.x", which I have not tested or run.


The SeaClear applications which I have tested and run also come with a small application named "Map_Cal" which is used to create calibrated map/chart images, and for setting which directories the SeaClear application will check/use for charts when displaying real-time position using a GPS.

Additional Comments

The only thing that I had to do is to make a sym link from dosdevices for the com port to the /dev/tty port and chown the /dev/tty port to my user. After that, everything worked flawlessly. More stable than in XP!

HowTo / Notes

Aug 3, 06 - Update

Thanks to Olle, the SeaClear developer, we've resolved all issues with this application.

The fix was to have MS True Type fonts installed. Once this is done, SeaClear works perfectly under WINE. :)


Thank you, Olle!!! :D

Using UK/Ireland Charts 2012 with SeaClearII
by Donald Paton on Wednesday March 7th 2012, 4:35
SeaClearII was downloaded and worked perfectly.

I purchased UK/Ireland Charts on DVD. I have dragged VMH_SC_Inst_?.2012 into .wine/drive_c as directed. I copied the shortcuts as directed. With the DVD still in the drive, I clicked on the Charts for SeaClear 2012 shortcut and I got the following popup:

[No Auto Launch file was selected or we could not locate it.

Please select the Auto Launch file within the configuration editor and save your changes.]

I can get no further. Can anyone help?
SeaClear II / Wine use 100% of the CPU.
by Henrik on Friday May 22nd 2009, 4:25

I'm having problems with SeaClear II v1.0.0.196.
After setting up the symlinks in ~/.wine/dosdevices pointing to my gps-device (GlobalSat BU-353 USB) everything works as expected, but for some reason WINE/SeaClear steals all available CPU-time. 100% all the time. This problem does not exist if I start SeaClear with the GPS disconnected, making me belive there is a problem with WINE's handling of the "serial" port. What confuses me is that nobody else seems to have run into this problem (according to google atleast).
Is there some setting or tweak needed?

This behaviour is verified in WINE 1.1.21 on both Kubuntu 9.04 and Vector 6.0.

I'm more than happy to supply more data/logs but maybe there is an easy fix that I just overlooked..

Thanks in advance..

Seaclear II + Wine > GPS not working
by Microyacht on Wednesday December 31st 2008, 12:33
I have installed Eeebuntu on my Asus Eee PC 900 together with the latest version of WINE. I have installed Seaclear II and everything on the screen is working apart from my GPS. It's an EverMore SA-320 USB Marine GPS which comes with a driver on CD. Installed on my PC, works perfectly with Seaclear and a few other Marine Navigation programs.

I tried installed the USB-Serial driver using the Wine setup utility. Not sure if I do need it but nothing seems to happen anyway.

I wonder if anyone can help me.

Many thanks

Happy New Year

Problem getting manual
by Donald E. Rock, MD on Thursday January 31st 2008, 11:35
I have downloaded SeaClear several time and although the icons appear on the desktop, I can get only the large world map to appear. I cannot get the manual or any menus to appear. I am using Ubuntu 7.10 and have upgraded Wine to its latest version.

How do I get the manual?

Thanks for any forthcoming information.

Seems to run great on PCLOS, as well. I have it loaded on a 12VDC mini-itx I'll put on the boat.
Seaclear and GPS
by Micke on Wednesday June 13th 2007, 9:43
Hi! Downloaded and installed Seaclear Thank you for a free useful program. It works but I have one problem with it. My GPS puck isn't recognized by the program? It's a Navibe. Any one that got an idea of how to get it connected?
But besides from that I can't use the program as it is now I like the way it looks and feels. ( Haven't tried it in Native Windows since I don't have that )
