[hpv-boats] Propellers

[Ken Pate]

Greetings All,

 

It's time for me to do a little research on propellers and such.  I was
looking at Rich W's. boat here:
http://www.rickwill.bigpondhosting.com/V11J_Dec_2008.jpg   and I noticed a
wide and steeply pitched prop.  I'm sure that this is a very efficient
setup, so are there plans/drawings for this prop?  How wide is it, and at
what pitch?  Are there props for sale?  If I have to make my own, what
materials would I use, wood, fiberglass, or...?

 

On a related thread what rpms do these generally run at, and what cadence is
typical for the pedaling?  

 

Thanks a lot,

Ken
