|On board we keep it simple. Should the batteries go flat, we can fall back
on traditional navigation using our Sestrel Major compass and our Walker's
Under normal circumstances we navigate the easy way, i.e. using GPS,
compass (we carry two, one magnetic and one electronic), log/speedometer,
depth guard and radar. The radar is our best friend as he already guided
us into a Portuguese port in poor visibility of <20 meters.
|Chart plotter yes or no?
"We don't need a radar as we already have a chart plotter."
These were the words of a collegue and we are deeply concerned about the
We do have a recent version of C-Map and can run it on our laptop computer
(if conditions permit it). By the end of 2005 the computer was interfaced
with GPS so you can imagine that this was not item #1 on our list of
priorities. But as "home" is further and further away, the less
detailed sea charts we have, so eventually we will use the computer more
and more. But our navigation is still based on paper charts!
won't run on Windows 7, but there is a solution. OpenCPN.
OpenCPN is a free software project to create a concise chartplotter and
navigation software for use as an underway or planning tool. OpenCPN is
developed by a team of active sailors using real world conditions for
program testing and refinement.
troubles: jumping mouse
Windows 7 and want to connect your GPS
to your laptop? Probably you'll experience the "jumping mouse" problem,
as Windows 7 thinks that your USB-to-serial adapter is a serial mouse.
Easy to adjust in the registry:
Open Regedit. (Windows-button + R)
Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SerMouse
and change the value "Start" from 3 to 4. Reboot.
There is reg software that will do the editing for you also.
Problem not solved?
Perhaps the problem is not solved with the above, or the mouse starts
jumping again after a couple of days. Do the following:
Donwload WDDK 7.1 from Microsoft, install the software and build the
environments as described in the manual.
Open Explorer and go to:
copy devcon.exe to C:\
Windows-button + R
devcon /disable *PNP0F09
