I haven't used the EarthExplorer plugin during real navigation yet. Trying the simulation, GE shows this big panamax container ship. Does this ship stays the same during real navigation or is there a way to change the ship icon to the one similar on OpenCpn?
MazatlanMexico ... Sorry, brick wall. The container ship is a 3D model built into the plugin. To use another model you would need to find a suitable model, the recompile the plugin. The OpenCPN icon is only involved because it can be given 2D dimensions to match those of the model.
