One of the
great things about Hover-ins is that you get a close look at some of the new
stuff that people have come up with. At the Chain o' Lake hover-in, the most interesting
innovation was the Webers' big foam prop....
The Webers' newest
craft sported a very high pitch, low rpm propeller made of foam and
fiberglass. I first saw this new style of prop when I saw the Webers at a
Hoverclub rally in Terre Haute Indiana. After you've been around
hovercrafts for awhile, it is eerie to see and hear this prop -- it is
extraordinarily quiet, and it turns so slowly that you think your eyes might
be playing tricks on you. Vernon told me that when he went cruising with
Bob Windt, Bob would look over and see the prop turning so slowly that he'd
be sure the engine had just stopped and the prop was slowing to a halt...
...and then it would just keep on going. At Terre Haute, I was standing
next to hovercraft manufacturer Gary Lutke of GPL when the craft rode by.
Gary laughed and said "That's not a propeller, that's a windmill!"
Here's Vernon with the craft, and here's a close-up of the
prop. I'll put up the construction and performance details (like the pounds
of thrust produced at a given rpm) after I get them from the Webers.
