The job today
Progress0%
Out, across, back. The cross legs are
surveyed too: they cut the offshore lines at right angles, which is what makes the profiles
into a surface.
Plan the day
Nothing planned. Add a move above.
Set the net, work the meadow, be home
before the front. Add the moves in the order you want them and the route follows the coast.

The breeze builds through the afternoon. Wave height
comes from wind and fetch, so the lee of a headland stays workable when the open coast
does not.
