Topographical map (2nd choice)
Poncho (for night use)
Flashlight (for night use)
(b) Navigator is positioned in center of boat and does not paddle. During hours of darkness, he uses his flashlight under the poncho to check his map. The observer (or #1 man) is at the front of the boat.
(c) The navigator keeps his map and compass oriented at all time.
(d) The navigator keeps the observer informed of the configuration of the river by announcing bends, sloughs, reaches and stream junctions as shown on his map.
(e) The observer compares this information with the bends, sloughs, reaches and stream junctions he actually sees. When these are confirmed the navigator confirms the boat’s location on his map.
(f) The navigator also keeps the observer informed of the general azimuths of reaches as shown on his map and the observer confirms these with actual compass readings of the river.
(g) The navigator announces only one configuration at a time to the observer and does not announce another until it is confirmed and completed.
(h) A strip‑map drawn on clear acetate backed by luminous tape may be used. The drawing is to scale or a schematic. It should show all curves and the azimuth and distance of all reaches. It may also show terrain features, stream junctions and sloughs.
