This is preparation material for whitewater SUP. Actually going out needs specialist training for that water and on-the-spot judgment.
A river can look calm on the surface while its flow and water level change. This material explains that for anyone about to try whitewater SUP for the first time, preparation and training come first.
01. Not something to start on your own
The original's first two points are: don't go alone, and learn the basic skills and river safety at a school or a whitewater camp. That doesn't simply mean you're ready as long as one other person comes along.
You need training and support to judge and respond to the hazards of moving water. Rather than starting whitewater SUP with just this article and picture, learn from an experienced instructor first.
02. Look at the map and the actual water together
The next points are to scout the route for obstacles and to check the water level at the start and how it changes through the day. After rain, or when levels are changing, even a stretch you know well can be different.
Check where you'll get in, where you'll get out and where you can stop along the way with a local instructor. Rather than pushing to keep to a schedule, sometimes you need to choose another day if conditions aren't right.
03. Learn a leash that suits the river, too
RNLI advises a quick-release waist leash on moving water where there's a risk of snagging. Don't assume you can just use the ankle leash you used at sea or on a lake.
It's not enough to own the product; you need to learn how to actually release it and which gear to choose for that water. As the original's last point says, plan short, suitable outings first so you don't go beyond the limits of your skill and fitness.
