The routes calculated by Orca are tailored to your boat and to the chart data for your area. To edit your routing preferences, open the Main Menu > My Boat > Routing Settings.
The available routing settings depend on which vessel type you have selected. You can change your vessel type via Main Menu > My Boat > Type.
