Introduction

There are a number of ways to assist someone that has flipped and is swimming.  Much depends on how close to shore you are.  If close, the most common way is bull-dozing or towing the boat to shore.  To save time if the paddler is still in their boat, a simple T Rescue is a good bet.  Sometimes when in deep water a distance from shore, you may wish to empty their boat over yours and hold it to stabilize while they climb back in.

T - Rescues

A T Rescue can be useful in large flat pools.  In most river situations, it is usually easier to move the boat and swimmer to shore where it is easier to drain the boat and get them on their way again.  If you are well away from shore in a calm area, you can pull their boat perpendicularly over your own, rock and empty.  Once empty, you still need to help them crawl back into their boat by holding it stable alongside your boat.  This technique definitely takes some practice.  One way to make it easier is turning the boat on its side to break the strong cockpit seal on the water.  Here is a nice video demonstrating this technique: T Rescue Demo.

Boat-Over-Boat Rescue/Importance Of Inflated Airbags

If you are attempting a boat over boat rescue like a T Rescue, it is much easier to do so from the rear of most kayaks these days.  Modern boats are shorter and most people only install flotation in the rear of their boats.  The front of the boat will be exceptionally heavy, too heavy to lift.  As a trip leader, you really should check beginners boats to ensure their air bags in the rear are fully inflated.  Fully inflated air bags help to ensure an empty boat stays somewhat near the surface of the river and doesn't get snagged underwater where it can be very difficult to retrieve.

X - Rescues

X rescues are typically done in deep and wide bodies of water.  There are several variations of this technique.  In a nutshell, you bring the boat alongside your own but face it in the opposite direction.  The swimmer can enter the boat either between the two boats or on the outside using a heel hook entry.  Once inside, they pump out the water and re-attach their spray skirt.  The following article describes numerous variations: X Rescue Article.
