• Photo map(1st choice)<br />

• Poncho (for night use)<br />
• Pencil/Grease pencil<br />
• Flashlight (for night use)<br />
(b) Navigator is positioned in center of boat and does not paddle. During hours of<br />
darkness, he uses his flashlight under the poncho to check his map. The observer<br />
(or #1 man) is at the front of the boat.<br />
(c) The navigator keeps his map and compass oriented at all time.<br />
(d) (d)The navigator keeps the observer informed of the configuration of the river by<br />
announcing bends, sloughs, reaches and stream junctions as shown on his map.<br />
(e) The observer compares this information with the bends, sloughs, reaches and<br />
stream junctions he actually sees. When these are confirmed the navigator confirms<br />
the boat’s location on his map.<br />
(f) The navigator also keeps the observer informed of the general azimuths of reaches<br />
as shown on his map and the observer confirms these with actual compass readings<br />
of the river.<br />
(g) The navigator announces only one configuration at a time to the observer and does<br />
not announce another until it is confirmed and completed.<br />
(h) A strip-map drawn on clear acetate backed by luminous tape may be used. The<br />
drawing is to scale or a schematic. It should show all curves and the azimuth and<br />
distance of all reaches. It may also show terrain features, stream junctions and<br />
sloughs.<br />
9-14. FORMATIONS. Various boat formations are used (day and night) for control, speed<br />
and security. The choice of which is used depends on the tactical situation and the discretion<br />

formations are:<br />
(a) Wedge<br />
(b) Line<br />
(c) File<br />
(d) Echelon<br />
(e) VEE<br />
