Presented is an improved waterjet propulsors that has application to air lubricated ships since it solves problems related to air ingestion into the waterjet inlets. This is done by disposing the waterjet inlets into side members of the ship disposed either side of the ship's artificially pressurized air layer(s). The waterjet inlets are best located, at least in their majority, lower than and aft of the ship's artificially pressurized air layer(s) and the side members of the ship are, in their preferred embodiment, extended aft of and, at least in their majority, below and aft portion of the artificially pressurized air layer. The improved waterjet propulsor can see improvements in its efficiency by absorption of ship boundary layer water. Further, air fences can be employed to restrict air from entering the waterjet inlets from either the ship's air layer(s) or water surfaces external to the ship.
