Routings started from the chart

The essentials

When underway, you sometimes want to know right away how to get over there. Several entries start a routing from the boat, at the current time, without setting a date or a route:

1. Switch to Navigation mode (“Navigation” switch at the top of the left drawer): the boat must have a position.
2. Display on the chart a wind GRIB that covers the boat and the target point.
3. Choose an entry:
   • on computer, right-click on the chart then “Route to this point”;
   • on all devices, “+” button then “Route to the target” (the target is by default the centre of the screen);
   • in a POI’s menu, “Route to this POI”.

The calculation uses the settings of your last routing: current, waves, polar, C-MAP options. If something is missing, a message says what.

Route to this point, to the target

“Route to this point” (right-click, computer) and “Route to the target” (“+” menu) start the calculation directly, without a window.

• The point of “Route to this point” becomes a POI when the calculation starts. It carries the date and time of the click (for example “Oct 7, 09:22”, followed by “UTC” if the app is set to UTC) and has no icon: its name is enough to find it. The routing has the same name.
• The target of “Route to the target” is that of the navigation tools: the centre of the screen by default, or the position fixed in its settings (see Navigation tools on the chart).
• The wind GRIB is the one displayed on the chart. Failing that, it is that of the last routing, provided it is on this device.
• The route is not saved in the list of routes: it lives in the routing, under a name starting with an arrow (“→Oct 7, 09:22”, or “→47°30N 3°05W” for the target).

What is checked before the calculation, with the message displayed if it is not the case:

The best start search does not apply to these routings: they start now.

Route to this POI

“Route to this POI”, in a POI’s menu, goes through the “Routing” window:

1. The app creates in the list of routes a two-point route, from the boat (“Start”) to the POI, named “→” followed by the POI’s name. If this route already exists, it is updated rather than duplicated.
2. The “Routing” window opens on this route, with “Now from my position” on and the POI as “Next Waypoint”.
3. Check the GRIBs and tap “Calc Routing”.

A boat position is required. If the app only has the last position received (the GPS link has dropped), the route starts from that position, at the time set in the window.

Calculate a routing from a route’s menu

Tap (or click) a route on the chart, then “Calculate routing” in its menu: the “Routing” window opens with that route chosen. What follows is described in Start a routing.

Route from a pivot point

To force a new routing through an isochrone point and compare two options, see Study your routing and pivot points.

Recalculate a routing

In the “Routings” tab, a routing’s ⋮ menu offers “Recalculate”. The entry is for when a more recent forecast is available:

1. it takes the routing’s route (in its current state, if you have edited it since), its weather files and its start time;
2. it downloads again the GRIBs for which a more recent run exists;
3. it starts the calculation with your current settings.

A routing that started from the boat restarts from the current position, now. The differences from the original routing can then be read in the “Inputs” tab of the routing’s details (see Read a routing).

When recalculation is not possible, the entry is greyed out and the reason is written below it:
