Eleven Sevtec sevs (4 Vanguards, 1 Surveyor, 3 Prospectors and 3 Explorers) at
the July, 1998 Pacific Northwest Hover-in. (Below) 3 more Vanguards in the
designer's backyard hoverport.

There are commercially constructed hovercraft that do just this, but you have to put up with incredible noise, lots of spray, and usually a cantankerous, high strung two stroke engine that guzzles amazing amounts of fuel. Some of these hovercraft are so loud, that if you use earplugs, you can still hear them with your teeth! No wonder there are not very many of them around, they are not very good neighbors. After all, skimming along on a cushion of air shouldn't take a whole lot of power, but the fundamental engineering has to be in the design to accomplish this.
The Sevtec line of sevs covers surface skimmers from a 12 to 25hp, single place Scout sev , 16 to 23hp, 2 to 3 place Vanguard sev , 25-28hp single engine, 4 place, or up to 41hp two engine Surveyor sev, 45hp Geo Metro 3 cylinder or 60hp 4 cyl inline single engine, 6 place, or up to 78hp two engine Geoduck sev, 80-98hp, 4 to 5 place Prospector sev, 80-98hp, 6 to 8 place Explorer sev. Plans and parts prices can be seen at The complete line of Sevtec sevs can also be seen on a graphics intensive page.
Search Sevtec for Sevtec newsgroup activity, including tips on building, operating and design of sevs.
As a home construction project, sevs offer an adventure of the level only associated with projects like homebuilt aircraft or ultralight aircraft. However, while some of the same building skills are used as are used in homebuilt aircraft or ultralights, a sev can be built for a tiny fraction of the cost and time that is required for home construction of a homebuilt aircraft.
Also, the Sevtec sev project, with its foam and fiberglass composite construction, can be a valuable training aid for someone interested in building a composite homebuilt aircraft, and provide a source of new adventure as well.
Sevs can be custom
built, or, Look at the new manufactured Vanguard at Amphibious Marine.
Videos are
available that show plenty of hovercraft and Sevtec sev action as well as
construction of sevs.

San Juan Island Sampler, or a Whale of a Tale is done! This 300 mile
roundtrip journey was made from the designers home north through the San Juan
Islands, using the Surveyor sev, overnighting along the way. Read all about it

Sevtec is continuously researching the surface skimmer concept, and as the
plans are computer drawn, they can be readily updated as new knowledge is
gained.
Builder activity and
Sevtec prototype sev images are shown here. (This section has grown too

Look at builder
activity on Sevtec sev builder web sites. Sevtec makes available the more
difficult parts such
as propellers and lift fans, skirt material, and drive hardware to ease the
construction of low noise, high performance, most user friendly skimmers
available to the homebuilder.
Join the adventure with sevs that have features unavailable on
almost all other surface skimmers.

The information package will be sent free to anyone
purchasing plans or videos or parts from this order form or parts
order form (Print out the order form using your browser or save the order form
as a text file, and fill it out off line) to order videos or plans or parts
right off these pages. If the order form cannot be printed out, state that the
order for videos or plans is off this web site and the information package will
be sent free of charge.
Some older sevs of the designer's are shown here. (Sevtec
throws away the old designs so the builder can concentrate on the newest and
best designs.)
The designer is available for engineering consulting and management of
serious commercial sev programs. Sevtec technical section
is available for those who wish to look deeper into the design of sevs. The
numbers do not lie, but the numbers do not show the part of design that is
called "art", which can be established by experience, only.

Do you
want to know what it is like to operate a Sevtec sev out in the "real world"?
You will find the real world is sometimes no place for undersized hulls and
front mounted lift fans as are on many hovercraft when you are away on an
adventure.

An
information package is available for $8 U. S. that describes all of the craft,
and is loaded with pictures and drawings, and an $8 price reduction coupon good
on any Sevtec product. (Only slightly more detailed information on the craft is
in the information package than is available in this web site.) (Mail check or

The
designer, a graduate in Mechanical Engineering from U. C. Berkeley, was
designing and flying flexible wing hang gliders as early as 1960, which was 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.)
