About

Amphibious Marine, Inc., a family owned and operated company, has been building hovercraft commercially since 1996.  The president/engineer, Bryan Phillips, has 42 years’ experience building and operating hovercraft.  Our craft have proven themselves on adventures as far as 1400 miles north to Alaska up the inside passage, 1800 miles on the Mackenzie River in Canada’s Northern Territory, in search and rescue applications, and for tourism operations running 7 days a week.

In addtion to building hovercraft we are dealers for Multiwing and Wingfan fans and blades.  We specialize in same day rapid repairs and shipment of fan and blades. Do you have broken blades and need them quick? We can ship same day overnight. While the store doesn't currently show Saturday delivery options, it is possible in some cases, but needs to be done manually. Call if you have questions. Most fan blades are cut when assembled to the hub at the factory. Therefore blades can be any length regardless of the printed numbers on the blade. It is best to tell us what diameter the fan is, or measure as shown here. We would need to know what hub type if you give a diameter, 5,6, 9,12 or 16?

We wish to acknowledge Barry Palmer, the original Sevtec designer, a graduate in Mechanical Engineering from U.C. Berkeley. In the early 60’s he began designing and flying flexible wing hang gliders, what would be the very start of the modern hang gliding movement.  He designed, built and test flew snowmobile engined aircraft he called “ultra-light” (as registered with the FAA in the Experimental Category) in 1967, at the very start of the Ultralight aircraft movement.  He has been plying the waters of (mainly) Florida and Puget Sound country in airboats and sevs of his design over the past 25 years, while serving as a staff engineer in aerospace, working on projects from rocket engines to spacecraft components and acoustics).  Today he is retired and lives in Monroe, WA.

Amphibious Marine, Inc. took over his hovercraft kits business in 2008.

Technical Data

Now, if one wants more reading on Sevtec craft all one has to do is “Google” up and click on the “groups” button and ask for Sevtec, or alt.rec.hovercraft.Sevtec or other things and just about anything will come up, including some technology discussions, as well as catfights and whatever usually goes on in newsgroups.

This paper, published in the Canadian 1984 International Conference on Air Cushion Technology, Sept 25, 26, 27, at Vancouver, BC may be old, but the numbers are just as valid today. A systems approach was taken to compare the Sevtec design philosophy directly to the design of large surface skimmers (hovercraft) with some surprising results.
