Propellors

[Tony Dunkley]

The feeling is entirely mutual I assure you.

 

Your figures are a load of tosh and there are other contributors to this thread who seem to understand the principals far better than you.

Oh I'm sorry I made a spelling/lexical error.

Your boats' excellent turning ability has nothing whatever to do with either propeller pitch or the engine torque curve...

 

If we wish to be pedantic and turn this into a grammar lecture:

 

Apostrophes

 

Rule 1a. Use the apostrophe to show possession. To show possession with a singular noun, add an apostrophe plus the letter s.

Examples:

a woman's hat

the boss's wife

Mrs. Chang's house

 

You must consider the pilot's thoughts in the context and circumstances in which he expressed them.

Firstly, he would almost certainly have had only the performance of similar relatively modern canalboats with which to compare the performance of your boat, and there is no doubt that modern boats don't make efficient and effective use of the engine power they have in comparison with the commercial carrying boats of days gone by. Size for size, a fair comparison would be a Leeds and Liverpool Shortboat. Fully loaded a typical power/displacement ratio of around 0.4 bhp/ton, and light (empty) around 1.0 bhp/ton as against a modern widebeam canalboat, with a minimum of around 1.6 bhp/tonne, and usually much more.

 

And I might be wrong but I thought "canal boat" had two words, not one.

 

Do you see how silly this sort of grammatical pedantry becomes on an boat forum?
