Depending on the size, organization, and capabilities of a nation's armed forces, the importance of patrol boats may range from minor support vessels that are part of a coast guard, to flagships that make up a majority of a navy's fleet.

There exist following sort of patrol boats: patrol boat fast (PBF), patrol boat with surface-to-surface missile (PBG), patrol boat inshore (PBI), patrol boat with SAM (PBM), patrol boat riverine (PBR), patrol boat with torpedo (PBT).
