Well, you've found your way here so you must have an interest in hovercraft. I'd guess you may either own a hovercraft, you're considering the thought of building one, or you've already begun a homebuilt project. This web-notebook is a collection of my own experiences and research regarding hovercrafting. I have basically focused on the SEVTEC design which I am most familiar with.

When I first became interested in hovercraft I was self-employed as a Commercial Gold Dredger in the Alaskan Interior. My job revolved around the ability to navigate and explore remote river systems. I wanted to expand my own reach and have an advantage over the competition. I thought a hovercraft would be just the right choice. With the unique capabilities of a SEV (Surface Effect Vehicle) I could go beyond where other boats had traveled to prospect new areas. I was very intrigued with the Sevtec design, which was described to me as the "SUV of hovercrafts." They are not necessarily intended as a high speed vehicle but are excellent watercraft for exploring and have very good maneuverability at any range of speed. I also liked the available cargo carrying space and capabilities of this design.

My first hovercraft building project began in 2000. I chose the Sevtec model called the "Vanguard" which was 14 feet long and powered by a vertical shaft 18 horsepower Vanguard engine. When I started I had no prior experience of working with foam, fiberglass and some of the other materials used. I learned as I went along and finally worked my way through to a completed and very useful craft I was proud of.

I would describe myself best as a ‘what if' type of person who proceeds through research, trial and error. These SEVs are really remarkable vehicles, but somehow I feel they are capable of so much more. What if...? Well, it would be a shame to not wonder ‘what if?' because without that consideration we would make no improvements. As you'll see I've tried a few different ideas with my crafts and not all of them have worked, but some have. In the end it costs me a little more time and money, but it keeps my creative thoughts alive and becomes a part of the whole hover-experience. The best part about our mistakes and improvements is that we can all learn and move ahead.

Operating or "flying" a hovercraft is a truly unique experience and something I have also learned my way through (with luck as my co-pilot!). It's so amazing to be carried by the work of your own hands, this is when it is all worth-while. Control of a hovercraft is like no other vehicle I have driven. They are affected by so many variables: Wind speed and direction, water flow and turbulence, the type and size of ground material, the balance of the load, obstacles in your path such as large boulders or fallen trees, the slope in any given direction, and the path of the river channel. Imagine yourself cruising a river at a good rate of speed and considering all of those factors with the ever changing terrain ahead of you. Now adjust to those conditions by using your throttle(s) for thrust and lift, using your braking ports, turning the rudders, and shifting your weight in the hull. Sound crazy? Well, exciting is probably a more suitable description.

These pages are some of my shared thoughts and experiences of hovercrafting. If you are considering a hovercraft you can look forward to a very rewarding experience. I encourage you to explore your own creativity in mechanics, to express yourself within the design of your own homebuilt project, and to experience the excitement of hovering.

I hope your visit here is both interesting and helpful.

Explore and enjoy!
