5 knots every rafter should know?

I'm signed up for a swiftwater rescue class next Spring. Prior to that I'd like to have some basic knots dialed in. What are the 5 knots every person on the water should know how to tie. I can tie my shoes and a tie, but that is about the extent of my knowledge 😱

Knots are super important. Practice the major ones as much as you can. You gotta be able to do them right, first try, even under the worst circumstances.

To the above list, I'd also add:
-The linesman's loop, aka the alpine butterfly knot.
It's a non-binding loop knot that will take pressure from either end, or the loop; and still come untied with ease.

I use it in place of a prusik in any z-drag scenario, so I practice it all the time.
Same job can be done with the alpine butterfly, and it won't burn thru your rope like a prusik can.
Once you know it well, it's super easy to reset, almost as easy as a prusik.

I never carry a prusik anymore....


-Another good one is the water-bowline knot.
It's kinda like a clove hitch meets a bowline.
Wet tubular webbing will slip with the regular bowline, but not with the water-bowline.

If I can only pic 5:


Figure 8 (best strength to ability to untie for making a loop)
Prusik (easiest for setting up mechanical advantage moveable block (pulley) points
Clove Hitch (easily adjustable knot at a fixed anchor point)
Munter Hitch (for controlled lowering/letting out loads under force)
Double Fishermans (for tying 2 pieces of rope or webbing together, I would use the water knot for webbing, but we can only pic 5 and a double fishermans will work)

That knot only gives you a loop in the middle of a line to attach a block to and it is a very good knot for that purpose. if you need to make more than 1 haul and re-adulst your blocks in a z-drag scenario then you will need a rope-grabbing knot, like a prusik, or mechanical rope grab device before you can let off tension and re-adulst the system, unless you have a secondary main line to the boat to tie off as a temporary anchoring line while you release the z-drag tension.

That linesman's loop's all you need to clip on a pulley mid-rope. Just hope ya got enough rope tho! No need for additional anchor lines, just don't drop the one you're gonna run thru the z, if you need to slack and reset.

I just like the ease of that knot, and that it doesn't bind up under a load....

Thankfully, I've only had to do 1 z-drag in a practical scenario in the past couple years.
We did have to release tension and reset the knot for more space between pulleys. Only once tho

Someone had a Petzl rope grab device down there. Under the right circumstances I could see it being really useful...
They didn't have it out before we got the boat tugged off the rock.
But I looked at it and really liked it, kinda wanna get one for my kit.

Alpine butterfly can be useful for isolating a damaged piece of rope while still using the rope.

Osprey's answer is right on.

All great advice. I would also recommend practicing these knots ad nauseum, at different angles, upside down, etc. I am spatially challenged and find that I can learn a knot perfectly while at home comfortable then find myself struggling when bent over in the cold at an awkward angle. When I used to climb, I would practice my knots in a cold shower in the dark. It worked.
