A shared list of boats for emergency patients in a char area

In the rainy season, when someone falls ill at night in a char village, time goes in finding a boat. The boatman is asleep, and not everyone knows who owns one. With the owners' consent, make a list of names, homes and when each can be reached. Put it on the walls of a few homes and on a board in a communal courtyard. Arrange fuel and life jackets beforehand. You need the boat owners' cooperation and one person to keep the list current. In an emergency, call 999.
