In its most basic sense, a fishing boat is any boat used, designed, or even just intended to facilitate the removal of fish from some waterway. There are a wide variety of examples, many of which are made specifically for nuanced circumstances. Commercial fishing rigs and boats intended for deep sea fishing often look nothing like those used by casual sportsmen on shallow lakes and rivers, for instance. Boats designed with a lot of high-tech features like on-board aquariums and rod holders are similarly quite dissimilar from simple wooden shells used by traditional fishermen both today and in ancient times. Humans have been capturing fish for food and sport for centuries. The earliest models were often designed around the available materials and the approach, for instance spear fishing and the use of nets. People still use simple boats and techniques in many tribal communities, developing countries, and hobby groups, but most of the modern versions are designed with more active technology. Anyone interested in purchasing such a vessel usually has a lot to choose from, and, with the right amount of time and flexible enough budget, can usually get something ideally suited for any circumstance.
