To make a raft use bamboo, uprooted trees, or tops of trunks.
Make sure to test your raft in safe water before setting off on a journey.
Make sure to tie all equipment very securely on the raft.
Check to see nothing is hanging over the edge.
Make sure each person on the raft has a bowline securing them to the raft.
In rapids, it is best not to tie on.
BAMBOO RAFT :
Cut thick style bamboo in ten foot lengths.
Make holes in middle and near the ends.
Pass stakes through holes to connect canes.
Using vines or twine, lash each cane to the stakes.
Make a second layer.
