BOAT This the Ultimate in
is an Australian Built THUNDER BOAT with a Rolls Royce
Merlin Aircraft engine fitted to it.
NOTE! A crane is used to put
these 30ft, 3 ton boats into and out of the water.
Note also that big stainless fin behind the sponson
for better cornering and this Hydro was built after I
had that fin attached to my little 18ft Hydro. Would
have liked to be let loose with one of these, owning a
gold or diamond mine would have helped..

was the Ultimate in Hydroplane racing in the United
States of America, where they race several of these
type of Hydroplanes. The driver is in a capsule
similar to fighter aircraft and the driver wears an
oxygen mask as well. Now instead of the Rolls Royce
Merlin aircraft engines, here they use a Lycoming T-55
L-7C turbine (Helicopter) engines. They turn
massive revs at the props with speeds in excess of 200
MPH ( Miles Per Hour, not KPH )
Note: With turbine engines they get more blow-overs,
as turbines do not throttle off instantly there is
always a lag. Thus if too much air gets under the hull
and the front starts to lift like a piece of plywood
in a high speed wind and usually over the boat goes.
See some hydro blow-overs below. Hence the use these
days of driver capsules with oxygen mask in case of
such a blow over.
