That looks like a Sev. Wouldn't be too surprised to see Barry Palmer log onto this board to promote his product. You don't want a hovercraft. I built one once, an 18 ft UH-17T. It worked, hauled butt with a 70 hp Subaru engine I yanked out of an old car. The problem with hovercrafts is number 1 they are absolutely uninsurable at least in the USA for liability or anything else, secondly they have to be built so lightly in order to be able to carry any significant payload that they are fragile and require frequent repairs (my 18 ft craft was covered with 1/8 inch plywood, with no fibreglass except at the seams), they are just very complex machines, having to have not only a drive system for thrust but also one for lift, whether or not they have separate engines for each system, or a complex transmission that allows one engine to do both, fourthly if the craft is homebuilt the trasmission system is also homebuilt, and the engine has been adapted to use in the hovercraft and isn't desinged for it, as opposed to a boat with an outboard that has been made for use on a boat, so if you have problems with the outboard you take it to the shop, and when no if you have problems with the hovercraft engine or transmission you fix it. Lastly, large hovercraft (like one that would hold 3 people) are extremely expensive if they are commercially manufactured, and if homebuilt take probably 1000 hrs to build. I once queried a group of hovercraft owners online about what they thought was the ratio of hours spent repairing their hovercrafts to flying hours, and the answer was 10 to 1. My experience was more like 100 to 1; eventually I gave up and destroyed my creation. An airboat, gas guzzling as it would be, is a much more practical alternative.
