Notes: This is a much larger version of the standard airboat listed below. They were typically used by hunting parties or to access remote lodges before the Twilight War, but during the war, were used as light patrol craft in swamps, marshes, and other areas with quiet water. They are basically larger versions of the standard airboat, carrying a much larger load of passengers or cargo at a cost to speed and maneuverability. Military or militia versions often had up to four weapon mounts around the hull.

Notes: This vehicle is most popular in swamps and marshes; some of the biggest users are located in the Florida Everglades and Louisiana Bayou country, though they are also used elsewhere. They are lightweight, maneuverable vehicles that can travel for short distances (4 phases or less) over dry land at one-quarter their normal water speed. Operating one takes a different sort of skill than normal boats; the referee may require the operator to have special skills within the Vessel Use (Boat) skill, but perhaps a better solution is a new skill, Vessel Use (Airboat). An airboat has no brakes, though some can reverse their propellers, and stopping and turning require good skill and training. They are very fast vessels, but not really suited for harsh weather or water conditions due to their light construction.

Notes: This is a military version of the standard inflatable raft. They are made by countries all over the world, by many countries, and are cheap and quiet. Most military versions have rigid bottoms to increase buoyancy and load-carrying ability. Some of the larger ones have a weapon mount in them, but this is not standard and is not included in the basic cost of the boat. They may be found with or without an outboard motor; the second speed, cost, and weight ratings are for when the boat is not equipped with an engine. They can be inflated by an air bottle in 1 minute, an air compressor in 1 ½ minutes, or a foot or hand pump in 1 minute per meter of length. A rare variation of these boats are Kevlar versions; these boats are two levels more rare than normal and 3 times more costly (for the boat itself, not the engine too).

Notes: The PBL (Patrol Boat, Light) is a small boat similar to many civilian "bass boats" in design. It is a simple hull with a central helm station and two powerful outboard engines at the rear to power it. It is not heavily-armed or well armored, and its main purpose is to provide a mobile surveillance platform. There is typically one weapon mount at the front of the boat.

Notes: This is more of a generic category instead of an exact boat type. The modern PBR (Patrol Boat, River) had its genesis in the Vietnam era Mekong River patrol boats; it uses a hull of extremely strong high-impact plastic, fiberglass, or carbon-glass fiber, and has several weapon mounts. They are typically diesel-fired and quite fast and maneuverable. They are also quiet and small, so they can slip into places that larger vessels can’t, carrying a load smaller boats cannot, and do so with some stealth. As this is a generic category, appropriate weapons for the country involved should be substituted for the weapons shown below in most cases.

Notes: The RIB (Rigid-hull Inflatable Boat) is a small vessel primarily used by US and NATO special operations forces, especially US Navy SEALs, but the Russians and Chinese also have a similar boat. The RIB is basically a collapsible boat with inflatable bladders stretched over a tubular metal framework. The design allows for a vessel that takes up less space aboard aircraft, has a high cargo capacity for its size, and yet is very buoyant and light. The RIB is inflated by compressed air canisters or a small air compressor that is attached to the framework and actuated by a pull on a lanyard. If compressed gas is used, the RIB fully inflates in 30 seconds; if a compressor is used, the RIB takes 3 minutes to inflate and the compressor must be held above water the entire time, an obvious liability during an airdrop or helocast into water. Another liability of both designs is the rubber construction, but a Kevlar version is available (3 times normal costs, and one level less common). Maintenance and upkeep on these boats is very light and cheap. The 6.4-meter, 7.4-meter, and 8.4-meter RIBs have inboard engines, while the rest use outboard engines. The RIB may be thought of as a patrol boat version of the inflatable assault boat.
