Thank you guys to everyone!! So, I read carefully the paper about the "cup" it's a good choice. What I can do at the moment is to bent the blade...
I can't change tip clearance and diameter, I can just move the pitch because I have to use this propeller I can't buy new one
thank you! :) It seems very hard, I have no curves as you talk about. I used the software propexpert. Can you suggest me a way to solve my...
Hi, thank you for answering me, I "re-pitched" it with a pitch of 890 mm. and my engine that is rated for 2300 rpm make just 2100 rpm, so I...

Hi guys! I am designing a concept 45' hull, I have used the ISO rules for the hull scantling. I want to compare the weight/cost between carbon...
Thank you John, it's very good for a general idea of the problem but not for a precise solution of the problem. I think that just the propeller...
Thank you every one, I'll use Gerr for a fast weight estimate, then I'll try to work with ISO rules. Thank you very much!
Thank you for answering me! and thank you for DNV Rules! If you have experience in the field whn you make a hull scantling you use register rules...
Hi! I was going to make an excel sheet to compare the ISO scantling and the Dave Gerr rules for a composite 45' top speed 45 kts. Someone...
