I'll bet Willie Nelson's bus is more fun.

Thanks for the buggy ride................

Wonderful exhaust tone on that bus.

Expected more of a turbine whine.

Thanks.

If stopping distance is such a problem, why no reversible prop?

Don't start me on hovercraft...

I am sitting in the pilot's seat of the biggest passenger hovercraft ever. A huge passion of mine.



SRN4 hovercraft in the the Hovercraft Museum, UK.

Many of them do have reversible propellers, but it is an added cost and complexity. Just learn to do a plow-in or up your skills.

It's like sliding on a wet bar of soap.

I've owned one for 25 years, been crazy about them since 1966 (age 6).

I was up in the SRN4 cockpit before our journey through the channel (1998 ish), the crew invited me to sit up there, but I declined because I did not want my wife to sit alone in first class.

Several of the hoverclubofamerica.org members have sat up there for the channel crossing, this was of course before they were decommissioned.

NOTE: I found out that you really want to sit in first class at the stern end. The bow is where most of the heaving is, the tail just drags a bit flatter in the whitecaps. I would have lost my lunch had I been forced to sit in the very front. Not sure if up on the roof would have isolated any of the heaving motion or would have made it even worse.

Odd in the marriage of wedge shape (lower body) and teardrop shape (greenhouse canopy), however it works in my opinion.

Wedge nose, blunt back, low Cd: it is possible.

Another example:

The Swiss designer Franco Sbarro wanted to demonstrate in 1985 that such a design could result in a very low drag coefficient. In this case it was 0.26.

I have visited the Lowman museum a couple of times. I hardly noticed the Sbarro (I'm a lifelong fan of the very oldest cars, e.g. pre 1910), but when I go back there I'll take a good look.

Low area cars each of them.

The rounded rear corners of the SBARRO may be Coandă effect ?
