Although there are many different types of racing vessels, they can generally be separated into the larger yachts, which are larger and contain facilities for extended voyages, and smaller harbour racing craft such as dinghies and skiffs. Smaller boats are not generally referred to as yachts, although all recreational boats (as opposed to commercial or military vessels) are yachts. These days, yacht racing and dinghy racing are common participant sports around the developed world, particularly where favorable wind conditions and access to reasonably sized bodies of water are available. Most yachting is conducted in salt water, but smaller craft can be--and are--raced on lakes and even large rivers.
