How do I change my automatic routing preferences?
Updated over a week ago

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.

Universal Route Preferences

These preferences are available to sailboats and powerboats.

  • Routing height limit - The routing engine will prefer to avoid bridges and cables lower than this value.

  • Routing depth limit - The routing engine will prefer to avoid areas, rocks, and obstacles shallower than this value.

  • Routing leeway - Adjust how close to the shore the routing engine prefers to follow.

Sailboat Route Preferences

  • Engine cruise speed - Used to estimate route arrival time. Set to your average cruising speed when near shore or inside restriction zones.

  • Minimum wind speed - Routing will switch to engine when windspeed is below this limit.

  • Polar scaling - Reduce your expected boat speed compared to your polar diagram.

  • Polar night scaling - Reduce your expected boat speed while sailing at night.

  • Polar beat angle offset - Increase your beat angle compared to your polar diagram.

Sail routing is also influenced by your Polar Diagram. You can change it via Main Menu > My Boat > Polar Performance.

Powerboat Route Preferences

  • Offshore cruising speed - Used to estimate route arrival time. Set to your average cruising speed when offshore and outside restriction zones.

  • Nearshore cruising speed - Used to estimate route arrival time. Set to your average cruising speed when near shore or inside restriction zones.
