BTW, when I bought my boat the weight and occupant load rating sticker was just that, a sticker. It faded and peeled off years ago.
Lol…mine came off after 1 day under the hot wind of a blow-dryer.
When I guided canoe trips we’d put everyone through some swamp, exit, and reload training before the start of the week. It happens, especially in small boats – and with river current it happens faster and is much harder to deal with safely. No reason to add risk by overloading a small boat.
