Hi there Jacqui!
I wonder if you could find out how the development team got this
project going? I'm sure most people, like me, wouldn't have a
clue how to begin. I know that projects can build their own
momentum once they're under way, but what do you do, maybe on
the first day? It would be fascinating to know! Good Luck with
your meeting with them at the weekend!

I saw the tribute to Donald Campbell three weeks ago. Strange to
think that half a century has passed since I heard the news of
his demise on BBC Radio. Donald is, I believe, still the only
man to have broken both the World Land Speed and World Water
Speed records in the same year. Quite sad to see the remains of
Bluebird after she was raised from Coniston Water in 2001. The
boat is being restored and will be capable of runs up to about
75 mph - enough to 'plane' but only a quarter of the speed
Donald was aiming for when his boat reared up and backflipped to
destruction. I'm sure the team on the new unmanned project will
have watched this many times, as well as some of the other
crashes like that of John Cobb. Today's hydroplane racers are
not immune from this kind of accident either. The idea that the
AI could try to prevent such a situation developing is very
interesting, and will make it more possible to 'take it to the
limit' without putting a life on the line. Some people will find
it less exciting because of that I suppose, but I call it
progress.

Hey there Jacqui! Just wanted to thank you for all you're doing
to bring us the breaking news on the project! Good luck with
your upcoming meeting with the team!

I really like this Forum! I'm going to be keenly waiting for
Jacqui's next report to see how the team are getting on. Good
luck you people!

Hi Jacqui! I just found the Forum and I hope I'm in time to ask
a question for your meeting. I was wondering how the boat will
be kept on course and in a straight line at very high speeds,
since the total length of the record attempt is 13 miles.
Presumably this will have to be handled by the AI, but what
about points of reference? It would be interesting to know the
team's thoughts on this!

I'm wondering if the boat will have to be quite large to travel
at very high speeds. Maybe a longer hull would be more stable
and not affected so much by small ripples in the water. Also,
perhaps a longer hull would have less risk of resonance with any
undulations in the water surface? I suppose that longer equals
heavier, so would require more power. It's probably a tricky
compromise.

Jacqui just phoned me to say that she's meeting the team leader
and two team members in the early afternoon tomorrow. So I'm
hoping that she'll be able to report back to the Forum later in
the the day. She's been told that the team are very impressed
with the Forum discussion so far, which is a tribute to all you
guys and girls out there who are contributing!

I managed to find out what a 'reverse three point hydroplane'
is. A 'hydroplane' is a type of boat that instead of having a
single hull, instead has a number of lower surfaces that cause
the craft to rise out of the water as its speed increases, so
that only small parts of the hull remain in contact with the
water surface. Usually there are three of these parts, two at
the bow end and one at the stern. A 'reverse' arrangement has
one at the bow and two at the stern. Generally hydroplanes can
achieve higher maximum speeds than single hulls of the same size
and power, but they tend to be less stable.

Since this project will obviously attract international
interest, I'm wondering if the team will be using Metric,
Imperial or Nautical units, that is kilometres per hour, miles
per hour or knots?.

Jack, I can answer this because I talked to one of the team
about it recently. She said that because they are all from the
UK and USA, they work only in Imperial units, like mph, pounds,
feet and inches etc. In America these are the only measurements
that are used by people, apart from some scientists who use
Metric. In the UK, which officially 'went Metric' in the 1970's,
most people and the media still tend to favour Imperial, and on
British roads the speed limits and signposts are all in mph and
miles. Cars in the UK have mph speedometers.
When the team is in touch with other countries that exclusively
use metric, they convert all their data to those units as a mark
of courtesy. It is simple to program the software so that any
mention of 'mph' is replaced by '[[x1.61] kph]', for example.
Knots are only used and understood by those involved in nautical
matters, aeronautics and weather, and are not understood by the
general public. Neither are they a 'universal' measure,
referring only to the speed of a watercraft, aircraft or wind.
One knot is actually 1.15 miles per hour.
The team aren't going to hedge their bets by publishing
something like "The boat was travelling at 100 mph (161 km/h /
115 knots)" because they think that would be a clumsy style to
adopt.
