A dive boat is a boat that recreational divers or professional scuba divers use to reach a dive site that they could not conveniently reach by swimming from the shore. Dive boats are usually powered by inboard or outboard engines. Some features, like convenient access from the water, are common to all dive boats, while others depend on the specific application or region where they are used. The vessel may be extensively modified to make it fit for purpose, or may be used without much adaptation if it is already usable.
