HSVA Profiles

[Ajanko]

Is there someone out there who can help me with HSVA profiles for rudderdesign?

I have been advised to use preferably HSVA MP 73 over NACA four digit profiles.
I would like to be able to do some HSVA plotting/calculations myself.
On the internet is a lot of data available about NACA profiles however not a trace from HSVA profiles.

The boat for which I will be using it is a 8,65 mtr. Colvic Watson motorsailor with a cruising speed of about 6 knots.
Anyone any suggestions?

Maybe you can get more help from HSVA:

Probably the best program for evaluating single-element sections is XFOIL. If you're considering using the HSVA profile, you must have the coordinates. So you can enter them into XFOIL and calculate the section properties for your operating conditions. XFOIL will generate NACA 4-digit section shapes for comparison. If you want to compare to a NACA 6-series or other shape, those coordinates are probably available from the UIUC airfoil data site.

There's a definite learning curve for XFOIL due to its command-line user interface. Profili is a graphical user interface for XFOIL that you may find easier to learn.

The best way to go is to use XFOIL to design your own section for your specific application.

Guillermo, thank you for this information, I will try to contact Mr. Mewis.
The Banjer 37 website is a nice site, I have visited it on a regular basis. There is a lot of information. I thought about buying a Banjer myself however draft of this vessel is a bit too much for this region.

Thank you for this information, I will look into this information, XFoil seems interesting. I will try to get hold of this coordinates and do some testing.
