bow lines between cleats on bay and bow bollards on boat. (Use 1 -inch manila line for steering lines.)

guys. Check traffic. Check and tighten bow and steering lines as needed.

CAUTION

Always position controls so that boats push raft against the shore during loading

and off-loading of traffic. Bridge or equipment damage could result.

Always secure raft to bank with approach guys during loading and off-loading of

traffic. Raft could be pushed away from shore causing vehicle loading/off loading

to dump into water.

NOTE

Rafts operating in a river crossing with more than one raft using the same loading

and unloading sites will follow a figure eight traffic pattern.
