Hi. While doing automotive routing on a GPSMAP 66st i found it had very difficult to calculate routes taking a ferry if the land masses were connected. This occurs over the Baltic sea and over the Mediterranean sea, etc. Very often, even if the most direct route is to take a ferry, the GPS unit did not even try. I therefor checked the default style and raised the travel speed of ferries (both car and passenger) one step in the style. I would like to share it in case anyone finds it helpful. In the lines file. From: route=ferry & (motorcar=no | motor_vehicle=no) [0x1b road_class=0 road_speed=0 resolution 23] route=ferry [0x1a road_class=3 road_speed=0 resolution 19] To: route=ferry & (motorcar=no | motor_vehicle=no) [0x1b road_class=0 road_speed=1 resolution 23] route=ferry [0x1a road_class=3 road_speed=1 resolution 19] This makes it easier for the unit to route along a ferry at least if shortest way routing is selected. Shortest time can still make the unit to try to drive around very large waters. I did not want to set the speed higher as road_speed=1 seems to make rather okay time calculation for ferry-trips.
