Scoop rescue
From KayakWiki
The scoop rescue is used to get incapacitated paddlers back into their kayak. The name really says it all.
Assume the rescuee is unconscious or injured to the point where they can't participate in their own rescue. The rescuer positions their boat parallel to the rescuee's kayak. Using a sculling stroke, move both kayaks up to the rescuee. Rotate the rescuee's kayak on its side thereby flooding the cockpit. Assuming the kayak has sufficient floatation, this should be OK and will sink the boat enough to partially submerge the cockpit rim. Then grab the rescuee's legs and shove them into the boat. Keep pushing them in until you've scooped their whole body into the boat. At that point, firmly grasp the rescuee's kayak and rotate it upright. Pump the boat out and you're ready to go.
Of course, if the paddler is incapacitated, you'll probably need to support them as someone else tows the two of you. If you are alone with the injured paddler, you'll need to lay them across the bow of your boat so they can support themselves on your bow while you paddle. I've practiced this quite a bit and while it works, it would be brutal to paddle this way for any distance.
