HoverCraft HomePage


2021 update

In my earlier days i got creative and built a 3 man hovercraft and a two man fuel injected Trike. This website is a collection of the build process i went through to achieve both those tasks.

The original website in general was written back in 2004-ish and for the most part of it has been left with the same wording as I had it back then, miss spellings and all :)


However nowadays I figured it was time to make it a little more user friendly. Back in the day I wrote the build website in HTML manually, but in this current day it looks ummm..... old :)

So recently I have tweaked the design and in some places, the wording, to be a little more relevant. I didn't go over board with the design keeping it simple and clean.



To begin Navigating:

- Click "start here" button above to start from the beginning of the build
- Or choose a category from the drop down menu above
- Or select from the menu at the top of the page

Anyway... let's get into it....


The Hovercraft was started in Mid October 2004, and I achieved my first test hover in one spot on 11th November 2005. The plans were purchased from ASV Australia and I have stuck to the plans up until the stage of mounting a duct, from that point onwards I'm working off the top of my head which could be classed as a scary thought.

So the main items I'm not sticking with in the plans are , Duct, rudders, length, width, steering, fan assembly and the motor
