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 firstname.lastname@example.org
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.
