You have probably already all the instruments on Your boat that You want. I haven't. My only instrument is a depth echo sounder - and a smartphone that is hard to see in sunlight. My sailboat is an old and small one: The Swedish Maxi77, 25 feet, from 1978. I made this small old-fashion Windows application to meet these requirements: - Spend no (or at least little) money. - Use one of my older laptops - placed/fixed in my boats cabin, protected against rain, seawater and direct sunlight - no big holes in the boat body! - Use my existing GPS-receiver with USB-interface. - Laptop screen, using big letters/numbers in full screen mode, must be visible from (almost) any position in the cockpit, sitting or standing up.

I am a genuine "hobby amateur programmer" and this software is therefore free only for non-commercial private/personal use. It comes with no kind of guarantees/warranties whatsoever, and I accept no responsibility for any malfunctions in the software - nor any adverse effects when using the software. Still: All kinds of feedback are most welcome! Use it purely as a supplement to good sailing and navigation practice. BRGDS and Safe Sailing ! Christian Wang, Kerteminde, Denmark

IMPORTANT: You will only be able to use SCOGinstrument if Your (USB/Bluetooth) GPS-receiver works with Your laptop!
