Planning long Yukon River trip in 18 foot Sotar raft w/oars and small kicker. Concerned about running up on silt/sand bars. Have 3 Sawyer composite 11' 5" long oars including handles and blades. Considering taking a 4th (Carlisle) oar to be primarily used as a push pole and emergency spare/spare rowing oar. No experience using a push pole on large raft (didn't want to trash expensive blades).
For the push pole, I am envisioning either modifying/reinforcing a HD commercial spare blade for pushing - or to perhaps add an extension to the shaft with a more appropriate end for pushing (which would also give me some flexibility on length). For anyone experienced using push poles, I would appreciate your thoughts on the idea of using a spare/spare oar as a pusher and what would be an appropriate length.
P.S. - This raft with its inflatable floor floats high and will not be over-loaded. Not expecting to be poling a great deal, but like the idea of perhaps/maybe being able to work off a silt/sand bar without having to leave the raft. Many thanks.
