Filters the trip list. A trip is offered only if the walk from the stop to the water and the walk from the take-out to the next stop are both within this.
Filters the ways off the water on the trip you have selected — nothing else. Set independently on purpose: nobody carries a boat 3 km, and everybody would walk it to get off a river in bad weather.
Trips longer than one regime's daily budget become overnight trips —
the return is then checked against the next day's timetable.
Exits must land within 50 m of a real path (120 m at a bridge).
Drag to pan, scroll to zoom. Stop size = services that day; colour = how late you can leave and still get home. Direct services plus one transfer.
