The "Black Space Polyconic Chart Bug" is more than annoying. In flyspray it is marked PRI=Low. I think it ought to be high. It happens in every instance I have tried. You can pan beyond the edge of any chart and the largest scale poly chart (if there is one) is not quilted.
I haven't done this on the water
, but, it is possible to place the boat Icon, using a right click, in the black space. To me this means that if I were coming out of Knife River, heading South, I could sail into the blackness. Scary.
I used Opencpn
(mostly 2.5) on a trip that started North of Baltimore
and ended in Guatemala
. I thought it performed very well. The earlier versions had stability problems, 2.5 didn't. That said, I don't think I will use Ocpn raster charts
, in Lake Superior
, until the bug is fixed. I can use the vector charts as long as I stay in US waters. The reason that I want to use raster charts is the Canadian raster charts are much cheaper for my sailing area, $150 vs $500.
