What have you tried? I dumped maxsea
a million years ago but
tried this? from Valhalla's page?
CONVERSION of MaxSea ROUTES AND TRACKS TO
the free version of GPSU is limited in the number of points it'll convert so you'd have to make chunks and stitch em together in O
or GPSBabel.. JimBim reports here Converting MaxSea .wpt Routes to GPX
he only gets wpts out of GPSBabel I'd maybe be reaching for my handy-dandy G72Win to put em together...
Somewhere, I noted the fix if you end up with a million (circles)waypoints instead of a nice line...can't find it-darn but it's out there.
