Anyone out there with a packraft have a good gauge for speed on a mainly flat water river with some rapids to class 2 on it?
I'm planning a trip that involves bikepacking and packrafting, and I need a general idea for planning purposes. I'm thinking ~2.5-3 mph (4-5km/h). The river gradient is ~2.4 feet per mile, and I'm hoping to catch it at a moderate to high flow.
