How high an object can a sea-going hovercraft fly over? ("Fly"? Well,
whatever the right word is.)

Depends on the throttle setting ?

Some years ago I was working for a defence contractor on a "sea
skimming" torpedo project - (supposedly Britains answer to the Exocet
missile)

I eventually found out that "sea skimming" meant an altitude of around
30 metres

Suppose a sea-going hovercraft is flying (I still don't know if that's
the right word) over calm water towards a wreck or a sandbank. I dare
say that in real life the helmsman will steer round such a thing, but
suppose he chooses to fly over it. How high above the surface of the
sea may the wreck/sandbank be to allow such a manoeuvre?

I think wrecks have to be avoided because once the hovercraft skirt is
damaged it doesn't hover well at all.

Sandbanks are different, in that they tend to have a slope up from the
sea rather than a cliff edge and the hovercraft just glides up it. I
rode on the experimental hovercraft service from Portsmouth to the Isle
of Wight about 50 years ago, and the craft carried on seamlessly from
the sea up the beach to the place where it parked for the passengers to
get on and off.

Sandbanks are fine for hovercraft, they skim over land as well as sea. The
issue is the morons in sailing yachts who can't navigate and who follow
the hovercraft across the Channel. Their keels are buried deeply in the
Goodwins.

Oh yes, I've seen them lol. I once thought Ekranoplans would be better
that hover craft but they 'never took off' haha
