I can understand why you want to make SeaClear work. OpenCPN is very nice for many applications, but I still like SeaClear better for some things. My 30 day trial with PolarNavy was a disaster. I thought it was very non-intuitive, although YMMV.

The problem you describe is well known for SeaClear, and emanates from the fact that USB is not part of the NMEA standard. For many programs that expect true NMEA, you need a software emulator that is designed to take the USB signal and map it to a COM port. My Garmin Oregon 400c works under SeaClear using Garmin's Spanner software, available for free download. Try that first.

SeaClear II won't recognize my Garmin 76cx

I don't have a serial port available, although I imagine I can find a serial cable for the gps, but I can't understand why SeaClear ii won't recognize usb ports. I can get maps in, etc... but can't hook up this dang gps! Ideas?

Re: Anybody tried SeaClear II free nav software?

SeaClear hasn't been updated or supported in ages. It was created to fill a hole when there was no free nav software available. That's no longer the case. You might want to try a different program. This thread is two years old and the two major software programs (OpenCPN and Polar Navy) have been continually updated and have good customer support.

If your GPS has a serial interface you can get an adapter for the computer that will give it a serial port. If your GPS has a USB interface you're out of luck.

Thanks for the response. I'm looking at them, but it seems they do not readily connect to a USB driven hand-held gps either!

Thanks,

I use it all the time. Bought a usb gps online for five bucks. Need to use the mapcal program inside the downloaded file to put the charts in the program. It's a bit more work then some other programs, but when put on automatic, I find it works as well or better.

Let me make sure I understand - you have a gps connected by a USB port and it's communicating with SeaClear?? I have the mapcal part worked out with the charts; I just can't get SeaClear to see my GPS (USB).

Re: Anybody tried SeaClear II free nav software?

I have a g-star IV usb gps. The seaclear program reads it automatically as long as it is connected to a usb port on your computer. When I bought a new laptop, I opened the program, plugged in the gps, and it read it again, without me telling it what port. When it's not plugged in it will tell me it can't read from that port, so seaclear begins looking for it. I've never had a problem and use it as my primary nav. I sail the SF bay area and the california coast. I bought the gps on ebay for 6.99. Just looked and they're up to 20 bucks, but that's still cheap.

If it's not reading your gps, maybe go into the tools section, look at the 'comm' tab, and try manually checking the different ports. ONe of them should work.

Re: Anybody tried SeaClear II free nav software?

Sea Clear is one of the first plotting programs but is pretty limited nowadays. It will only read Raster format, available from NOAA but few other sources. It will not read ENC format. You can create your own raster charts of other areas by using GE pictures but I wouldn't trust these. Almost free is the Polar Navy program which is a great little program for little money.
