Hopefully someone has made this trip so I can craft a realistic scenario for a novel I’m writing.
Assuming you had a crew of one experienced paddler and two inexperienced paddlers, about how long would it take to traverse the entire length of the Belize River upstream in July/August from Belize City to Branch Mouth Park (where the river starts)?
Are there places requiring portaging? Apparently there are 78 runs or rapids, but I believe they are only Class I and II. Possible some are Class III.
How many hours a day could they paddle, assuming all are reasonable fit?
Approximately how many miles a day would they progress?
EDIT: This would be in the mid-19th century, so the canoes would be birch-on-frame or wood-and-canvas construction. Maybe 17’ long?
It appears during the wet season the flow rate is 15 cubic meters per second.
