Wing-in-ground (hereafter referred to as WIG) vehicles operate a few meters above water. The vehicles make use of the ground-effect (an effect where the drag is reduced, and the wings of the vehicles generate an increased lift). The unique speed and distance range of a WIG vehicle — a vehicle that, in functionality and appearance, sits somewhere between a ship and an aircraft — could be an ideal option for high-speed passenger transport on routes with ‘medium’ distances. That said, WIG vehicles have hardly ever been seen in civilian applications, such as high-speed passenger transport. This report answers the question: can WIG vehicles operating as high-speed passenger ferries, be feasible and profitable? This feasibility is assessed on the basis of literature research and real examples of WIG performance, functionality and profitability. Suitable routes and vehicles are selected based on criteria analyses. Using financial estimations, the profitability of two suitable WIG vehicles on two separate routes is investigated.The specifications of recently built WIG vehicles and their design drivers are analyzed by performing a literature research. This information reveals that WIG vehicles have one main limitation: a low seaworthiness. It is then likely that this limits the seakeeping operability for a number of vehicles. To deal with this limitation, suitable vehicles are selected using a criteria analysis. The literature research shows that the WSH-500 and the Aron M80 both have a relatively good seaworthiness. The vehicles differentiate in size (48p & 6p). The costs of the vehicles are estimated by using general aviation cost estimation theory. A criteria analysis based on seakeeping operability and number of passengers and distance, shows two suitable routes: ‘Buenos Aires – Montevideo’ and ‘Helsinki – Tallinn’. The potential demand for WIG transport on these routes is estimated by creating demand curves of transport. The strategy to market WIG transport on these routes is estimated by using a market research to gage the potential demand. A suitable strategy is to target the top niche of customers on these routes. The profitability is estimated by combining the suitable vehicles, cost of vehicles, routes and strategy. The net present value and internal rate of return is calculated for a number of cases that are explained in this paper. The cases vary mainly on the following aspects: vehicle, total investment and route. In conclusion, WIG vehicles operating as high-speed passenger ferries can be feasible and profitable. The technology behind WIG vehicles has a technological readiness level of 8 out of 9. There are multiple, full-scale prototypes made and tested. Suitable vessels and routes have been selected to deal with the primary limitation that comes with WIG vehicles; they have low seaworthiness capabilities. The seakeeping operability rates of the selected vehicles and routes range between 91% and 100%. The net present value (NPV) and internal rate of return (IRR) of investments made in a WIG transport company can be positive in a number of cases.
