A kayak is a tiny, thin boat that is propelled using a double-bladed paddle. A classic kayak features a covered deck and one or more cockpits, each of which seats one paddler. Modern variations include sea kayaks and whitewater craft. Although they are different types of vessels, all kayaks are generally unstable and non-planing. Kayaking is becoming increasingly popular worldwide. In fact, according to the World Kayak Federation, there are nearly 20 million people participating in some form of kayaking today. Because it is such a diverse activity, it can be done by anyone from novice paddlers to experienced kayakers. Even if you have never been on a kayak before, you will soon discover how easy it is to navigate across lakes, rivers, and oceans thanks to the stability afforded by this unique vessel. There are many reasons why kayaking is becoming so popular. For starters, it is one of the most environmentally friendly sports around. You don't need any special skills or equipment to go kayaking, which makes it perfect for beginners. Also, because there is no motor to stall out or tire to blow, you can go much further than when skiing or riding a bike. Finally, it is one of the cheapest ways to see exotic places. You can easily spend a week exploring remote areas by kayak instead of a month driving around in a car!
