Hello Oscar,
Unfortunately we only have the polars of an Ovni 435 which is a different and smaller boat.

As a suggested path-forward you could develop your own data with other Ovni 445 owners interested (a lot of useful data can be recorded automatically by some navigation softwares), as it was done for the 435, and/or use a Velocity Prediction Program (VPP), some are open source.
All the best, Kev

Hallo,
when looking for 435 polars , I found the ones for the 445. The PDF file was sent to me by Alubat (Mrs Trichet).
I attach the pdf file here.

From the PDF file, I created the .POL file compatible with the VPP open source software QtVlm. I do not succeeded to attach the file here (extension not allowed), but feel free to contact me on gbaraus@gmail.com and I can send it to you.

The routes created in QtVlm can be imported in many navigation SW, including the free one OpenCPN. Pretty handy. Many info are available on the web.

On the other hand I still do not have the 435 polars, which I understand exist. I would be grateful to receive them.

Hello Guido,
Thanks for sharing. Just sent you an e-mail. Only Ovniclub members (user name in orange) have access to this part of the forum. You just need to complete your profile with your boat references to automatically become an OvniClub member, it's free of charge.
The Ovni 435 polar charts we have are estimated ones from actual navigation conditions and discussions among 3 Ovni 435 owners. It's different from the VPC, calculated from the boat architectural data, which are theoritical and usually higher .
All the best, Kev
