Not aircraft surplus, trust me.

Anything over 30 mph demands aerodynamics in my opinion.

This isn't like a boat displacing water that's 100 times denser than air.

A hovercraft is lubricated from the surface by 1/2" or more of air escaping from the partially captured cushion of air beneath the craft.

I'm pretty sure that craft can do about 50 mph, faster with a tail wind.

Speed
Max. Speed: water 80 km/h

ice and packed snow 120 km/h

Cruising Speed: water 60 km/h

ice and packed snow 70 km/h.

(Max. speed is dependant on weather and operation platform condition)
EDIT-2

I did a conversion online

80 km/h = 49.7097 mph

120 km/h = 74.5645 mph

Cruising speed on water 60 km/h = 37.2823 mph

Aerodynamics would certainly become a factor.

If I posted other hovercraft you would recognize just how special this craft is, many of the other ones are crude looking by comparison.

These are two different makes, and the Christy above (Russian) was formerly one of the cleanest designs, it's been displaced by the Finnish hovercraft below.

The British Griffon isn't a slouch, but most of their models are boxy, but getting better all the time.

Looks like future models will be following suit.
