I am looking for a book on building a Propeller tunnel

I understand there is a book that details the info on building a Propeller tunnel . can anyone help with the title? Thanks

 

Probably no books, but there may be a paper or two.

Google..... "propeller tunnel design" for a fair number of hits.

Edit: e.g. by Blount


https://www.boatdesign.net/attachme...p-pocket-design-propeller-tunnels-pdf.101525/

 

Dave Gerr's "Propeller Handbook" has a couple of pages on ducted propellers. https://www.amazon.com/Propeller-Ha...ller handbook,stripbooks-intl-ship,280&sr=1-1

 

If you can find any information from Donald Blount it will probably be a bit more recent than the pages that Peter du Cane devoted to the subject in one of his books.

 

I am interested in this too!

 

I didn't see this thread until now. Endresen (founder of Servogear) did a lot of work on tunnel optimization too. I have not taken the time to dig up any of his papers but there is a design guide on their website that may be of some interest. I had the opportunity to work with Endresen and the installation of one his earliest systems on some high-speed catamaran ferries built in Norway back in the early 90s.
