Hi Bob, I have run my 2010 Mokai on several rivers in my area, Vancouver, WA, where the water varies from flat with 3 - 4 mph currents to class 1 and 2 rapids, without difficulty. On the Columbia, I have to be careful to avoid large wakes from cruisers and wind driven waves above about 3’. On the swift rivers, I have to judge whether or not my boat can run faster than the current in chutes and swift runs.
Going upstream is generally easier to navigate as you can often stop before you get into trouble and reassess the navigability. Coming back downstream is not so forgiving. Standing waves below a chute can swamp your boat in a heartbeat. I would not attempt them without a windshield or, at least a splash guard. I try to aim for the eddies when possible. Also, I have learned to keep my paddle handy so that I can maneuver in the event that I lose propulsion from the engine.
Mokai’s are very stable boats having a low center of gravity. They can handle pretty heavy water when under power which enables keeping the bow high. They tend to plow a bit at low power. I would not attempt cross the Columbia in 25 knot wind under paddle. You will build your confidence as you gain experience on the water.
