I have bought the book and read it! Quite an accomplishment for a state educated numpty.

Enough about me, it is time to say any boat modeler this is a must read.

For me it is a great read, about technicalities, what could have been and should have been, if those traditionalists, would only have recognised and appreciated that there is benefit from listening and adhering to contracts, the wishes of the bill payers, and professional engineers.. A bit boring for some, yet a good read.

The fact that jet X motors, were used in testing models, gives me hope that I can complete my own similar sized model.

The book is available for £20, delivered, from Thrift books, quite a discount from many sites.

I drew up my own plan, based on a drawing on the Internet, studying photos on the internet. Then the project stalled, partly not being clear where the CG should be. Then I had and have drive line issues, wanting to use a flexi drive shaft.

More recently I decided that the CG needs to be pretty far back.

The initial thoughts were using a (I think) 7 cell Sanyo Nicad, using a 480 motor.

My present thoughts are a Inrunner using a Lipo. I probably now would now use a solid shaft, at a shallow angle. With the passage of time I am thinking of about, 150-200 watt motor. I now need to identify the most useful KV.

Finishing is the most problematical set of issues now.

In a way the book did help in understanding a little of what was intended.

With respect to Bluebird, it is evident that the forward 3 pointer is not the only concept. As the Spirit of Australia is not apparently a 3 pointer of the Bluebird or Crusader type.

As for scaling speed, dimensionless analysis is often used to provide a pointer. I have no idea as to what is an appropriate set. What is certain is that the Froude relationship is not the one. As it really tells you a long hull narrow beam provides the highest speed for a set power input, for a displacement hull. |Mentioned in the book, much to the disappear of Railton.
