Fasten the tow line to one end of the kayak, preferably the bow, and clip or tie the other end around your waist. Since you can't tow your partner inside the swamped boat, they have to swim along side holding onto the back of your kayak. A slack line over the back can assist a fatigued swimmer; this will be slow going, but you will get to shore.
Overturn and towing maneuvers are learned and practiced. This kayaking tip may require training with hands on instruction. However, once you've learned the technique, you'll never have to worry about an overturned kayak again.
